In many species, particular groups of animal pollinators have shaped floral evolution resulting in the recognition of distinct pollination syndromes (Fægri and van der Pijl, 1971; Proctor et al., 1996; Fenster et al., 2004). Our online platform, Wiley Online Library (wileyonlinelibrary.com) is one of the world’s most extensive multidisciplinary collections of online resources, covering life, health, social and physical sciences, and humanities. Floral characters of Tacca chantrieri based on samples from the XTBG population. The … Pollinator visitation was infrequent and bagged flowers set abundant seed. As a result, we have remarkably little direct evidence on the effectiveness of different pollinator groups in promoting cross‐fertilization, or whether some syndromes are more susceptible to self‐pollination than others. A 2005 study done in South Yunnan province, China found that almost nothing visited the flowers of Tacca chantrieri. Also known as: Bat Plant, Cat’s Whiskers, Devil Flower, Black Bat Flower, Bat Head Lily, Devil’s Tongue, Black Tacca, Jews Beard or Voodoo Flower . Similar analysis of seed : ovule ratio indicated no evidence of a population effect but a significant effect of pollination treatment and population × treatment interaction (two‐way ANOVA on seed set, F3,92 = 2.69, P = 0.05, population, F1,92 = 0.40, P = 0.528 NS, pollination treatment F1,92 = 4.43, P = 0.038 and population × pollination treatment interaction F1,92 = 3.90, P = 0.05). 2Xishuangbanna Tropical Botanical Garden, The Chinese Academy of Sciences, Yunnan 666303, China; 3Department of Botany, University of Toronto, 25 Willcocks Street, Toronto, Ontario, Canada M5S 3B2. This reduced the motility of the long filiform bracteoles, which, as proposed by Fægri and van der Pijl (1971), may serve in pollinator attraction. A total of 320 samples of T. chantrieri were collected from 24 field populations in mainland Southeast Asia, covering most of the distribution range of this herb ( Table 1 and Fig. — Annals of Botany 98: 449–457. Visualization and interpretation of plant isozymes. Pollen loads on stigmas indicated autonomous self-pollination, some of which occurred prior to flower opening. For this treatment, not all flowers within an inflorescence were cross‐pollinated because of the technical difficulties associated with bud emasculation in this species. Bats are important pollinators of some tropical flowers, visiting to take nectar. 2005; Zhang 2006; Zhao and Zhang 2015). The flower stem develops from the base of the plant, and it can be around 24 inches long. Following the presentation of our results, we discuss the relations between floral traits and mating and propose several explanations for our unexpected discovery that populations of T. chantrieri are predominantly self‐fertilizing. These amazing blossoms appear from spring and on through summer. This seems doubtful in the case of T. chantrieri, as extreme specialization would be unlikely in a species in which the only apparent floral reward (pollen) is easily accessible to most insect visitors. Despite possessing a suite of traits usually associated with sapromyiophily, our investigations of T. chantrieri failed to reveal deceit pollination mediated by flies. 1). Among the four populations of T. chantrieri examined in this study (Table 2), estimates of the population‐level maternal selfing rate (sm) based on three polymorphic allozyme loci averaged 0.86 (range 0.76–0.94). For treatment (2), we bagged inflorescences on each individual prior to anthesis to prevent access by pollinators. vs 2020 1; 2018 2; 2017 … We consider next several hypotheses that may explain the association between the sapromyiophilous syndrome and high selfing rates in T. chantrieri. Fruit set data were arcsine transformed prior to analysis. The main attraction of this plant is its flower, which is an umbel (a flat-topped inflorescence with numerous flower … Indeed, the syndrome could function in other populations of T. chantrieri elsewhere in its range. Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker‐like filiform bracteoles. The low pollen : ovule ratio (49) of T. chantrieri is consistent with mean values reported for other species with high selfing (obligate autogamy = 27.7, facultative autogamy = 168.5; Cruden, 1977). This led the authors to suggest that most bat plants are self-pollinated. material attracting flies that facilitate cross-pollination (sapromyiophily). Despite the presence of numerous potential pollinators, only a handful of small, stingless bees paid any attention to these obvious floral cues. — A: Flower. Trova tacca chantrieri in vendita tra una vasta selezione di Piante, semi e bulbi su eBay. Flowering plants are characterized by striking variation in reproductive systems, and the evolutionary lability of their sexual traits is often considered a major driver of lineage diversification. - "Predicting mating patterns from pollination syndromes: the case of "sapromyiophily" in Tacca chantrieri (Taccaceae)." The seed set of inflorescences with bracts and bracteoles removed was not significantly different from unmanipulated inflorescences, suggesting that these structures play a limited role in pollinator attraction, at least at our study sites. Two days prior to anthesis, the flowers were emasculated to prevent prior self‐pollination. At WEV, we observed occasional visits to plants by a few ants, spiders, and flies, but these visits were also not effective in pollination. We initially screened for electrophoretic variation in enzymes on two buffer systems: aspartate amino transferase (AAT), alcohol dehydrogenase (ADH), glutamate dehydrogenase (GDH), cytosol aminopeptidase (LAP), and triose phosphate isomerase (TPI), on lithium‐borate (pH 8.3); and aconitase (ACO), acid phosphotase (ACP), isocitric dehydrogenase (IDH), glucose‐6‐phosphate dehydrogenase (G6PDH), malate dehydrogenase (MDH), phosphoglucose dehydrogenase (6PGD), phosphoglucose isomerase (PGI), shikimic dehydrogenase (SkDH) on histidine‐citrate (pH 6.5). Number of times cited according to CrossRef: Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species. Tacca chantrieri is an unusual plant in that it has black flowers. Corresponding values for XTBG were 10–27 (16.0 ± 0.6, N = 50) flowers per inflorescence, and 62.85 ± 15.2 (31.6–86.7, N = 25) fruit set and 49.2 ± 8.3 (33.1–64.4, N = 25) seed set, respectively (Table 1). — American Journal of Botany 92: 517–524. 2a, b). Destabilization of mutualisms can occur if pollination systems are highly specialized and pollinators are lost from a region (Bond, 1994). These tropical evergreen flowers produce large, pure white petals centred by small, sombre, drooping flowers and long whiskerlike bracts, all resembling a bat's face. Tacca chantrieri has extravagant floral displays and a high investment in reproductive structures that lead to the expectation that it is largely outcrossing (Drenth, 1972; Saw, 1993). The leathery capsules about 4cm (1.5 inch) long require up to a year to ripen. Their experiments provided no evidence for an obvious adaptive role, and they proposed that this structure may be selectively neutral persisting after its original function was lost. 4.0.4, SAS Institute, 2002) with both population and pollination treatment as fixed effects. Saw (1993) reported a musky smell in T. integrifolia, but we were unable to detect any odor associated with the flowers or bracts of T. chantrieri. These features have been assumed to function as a "deceit syndrome" in which reproductive structures resemble decaying organic material attracting flies that facilitate cross-pollination (sapromyiophily). 2006: Genetic diversity and geographic differentiation in Tacca chantrieri (Taccaceae): an autonomous selfing plant with showy floral display. Our study of mating patterns in T. chantrieri was conducted in four populations during a single flowering season. Tacca chantrieri is an excellent system for evaluating the population genetic structure and phylogeography of herbaceous plants since it is widely distributed throughout the humid tropical forest understory in the Indo-Burma area (Drenth, 1972). Plants are 50–100 cm tall with tubers or creeping rhizomes and alternate, elliptic, entire leaves. View picture of Tacca Species, Bat Flower, Cat's Whiskers, Devil Flower (Tacca chantrieri) at Dave's Garden. Tacca cristata Mean percentage fruit set of bagged inflorescences was 74.1 ± 3.2 (N = 26) at WEV and 61.2 ± 3.2 (N = 25) at XTBG. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. We investigated pollination and mating in Tacca chantrieri … Access supplemental materials and multimedia. This plant is distinctly tropical. Tacca chantrieri: la pianta “tenebrosa” che ricorda un pipistrello Informazioni generali. Amots Dafni, W. John Kress, Jeff Ollerton, and Shuang‐Quan Huang for constructive discussions and comments on the manuscript; Mr. Neil White for assistance with allozyme analysis; Mr. Xiao‐Dong Yang and Pan‐Yu Ren for some art work on photographs; Dr. L. G. Saw for providing his reference on Tacca, and Dr. S.‐Q. Tacca chantrieri Synonyms: Bat Flower, Cat’s Whiskers, Devil Flower, Tacca integrifolia chantreieri. Leaf material was collected at intervals of at least 10 m, and plants were chosen randomly. Therefore, we have no information on whether our manipulations influenced pollinators in any way. The seed set of inflorescences with bracts and bracteoles removed was not significantly different from unmanipulated inflorescences, suggesting that these structures play a limited role in pollinator attraction, at least at our study sites. B, Tacca chantrieri manifests many floral traits corresponding to fly pollination, yet it has a high selfing rate, likely corresponding to delayed selfing, when the flower inverts and the pollen spills onto the stigma (photo courtesy of Q.-J. 2e). We photographed all types of flower visitors, and voucher specimens of insects are preserved in the insect collections of XTBG. In Yunnan Province, SW China, the region in which our studies were conducted, the species flowers from April to July. In some contemporary populations, the syndrome could be selectively neutral, and developmental constraints may have prevented significant evolutionary modifications. Compralo Subito. Tacca chantrieri commonly known as black bat flower is native to the to the subtropical and tropical rain forests in Central Asia. Anthesis commences at the center of the inflorescence with one to four flowers (usually one or two) in anthesis each day. Plants are 50–100 cm tall with tubers or creeping rhizomes and alternate, elliptic, entire leaves. Latin tacca, from the Indonesian name, taka; Latin integrifolia, with entire leaves: Ethnobotanical Uses: Medicinal ( Rhizomes used in Traditonal Chinese Medicine to treat gastric ulcers, burns and high blood pressure and burns, as well as improve sexual function. TABLE 1. Pipistrello NERO FIORE-tacca chantrieri-semi-quantitativi di selezione. This work was funded by NSFC grant 30225007 to Q.‐J. Birds, particularly hummingbirds, honeyeaters and sunbirds also accomplish much pollination, especially of deep-throated flowers. These features have been assumed to function as a "deceit syndrome" in which reproductive structures resemble decaying organic material attracting flies that facilitate cross-pollination (sapromyiophily). The unique black flower looks like a bat. Furthermore, an exhaustive study on the repro- (Taccaceae), a New Species from Yunnan, China Its pollination takes place through small mammals and rodents who eat its fruit. Tacca ampliplacenta L. Zhang &. Fioritura: (Aprile – Agosto).Fiori di color viola-nero. Flowers of T. chantrieri do not produce nectar or any odor that we were able to detect. Tacca chantrieri André is perennial plant belonging to the Taccaceae family. Tacca Nivea: Family: Taccaceae Origin: Malaysia . Pollinator visitation was infrequent and bagged flowers set abundant seed. The second site was in a protected area of Xishuangbanna Tropical Botanical Garden (XTBG; 21°45′ N, 101°02′ E; 580 m a.s.l.) . When they split along their sides, numerous 0.5cm (0.25 inch) seeds are revealed embedded in a sticky pulp. It flowers in spring time. When flowers were emasculated just before opening, they produced 42.3% ± 4.1 fruit set and 28.4% ± 3.24 seed set. The three treatments were: (1) an unmanipulated control, (2) the removal of bracts and bracteoles, and (3) staked inflorescence. Furthermore, an exhaustive study on the repro-ductive biology of T. chantrieri in Yunnan showed little evi-dence of … We then address the following specific questions: (1) How is pollination achieved and what is the functional significance of the extravagant display? 1), and it is possible that in other parts of the range floral traits associated with sapromyiophily function more effectively in promoting fly‐mediated cross‐pollination. Temperatura minima: 12°C. and is dominated by Pometia tomentosa (Sapindaceae). Tacca chantrieri. patterns from pollination syndromes: The case of sapro-myophily in Tacca chantrieri (Taccaceae). Famiglia: Taccaceae. TABLE 1. Bat Flower, Tacca chantrieri. Tacca chantrieri is a widespread species that occurs in humid tropical regions of south-east Asia. Ancestral reconstruction of flower morphology and pollination systems in Schizanthus (Solanaceae). Pollinator visitation was infrequent and bagged flowers set abundant seed. and Tacca chantrieri André, demonstrate a very high degree of geographical population stratification, consistent with a hypothesis of self-pollination (Zhang et al. The extracts were adsorbed onto chromatography‐paper wicks (Whatman's 17 wicks, Maidstone, UK), and placed directly onto 12% starch gels (1 : 2, hydrolyzed potato starch, S‐5651 [Sigma, Missouri, USA] and CAT 32823 [USB Corporation Ohio, USA]). 2005; Zhang 2006; Zhao and Zhang 2015). Tacca chantrieri. Indeed, flies are often considered the most dependable of animal pollinators, at least in terms of abundance (Larson et al., 2001). Fig. Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker‐like filiform bracteoles.

Floral Visitation, Pollen Removal, and Pollen Transport of Autonomous Selfing Provides Reproductive Assurance in an Alpine Ginger Roscoea schneideriana (Zingiberaceae). Contrary to this expectation, populations were highly selfing. The first site was at Wild Elephant Valley (WEV) in Mengyang Nature Reserve, (22°10′ N, 100°51′ E; 760 m a.s.l.) We set up three treatments with 30 individuals per treatment using one randomly chosen inflorescence per plant. We have provided several hypotheses that might explain the association between high selfing and the sapromyiophilous syndrome in populations of T. chantrieri in SW China. 2 Morphological variation of Its wing-like bracts are a deep purple and have the appearance of bat wings. The autonomous selfing mechanisms and low pollen : ovule ratio of T. chantrieri are certainly consistent with this scenario; however, the sub‐maximal fruit set that we recorded in open‐pollinated and bagged flowers are not expected in populations with a long history of selfing. You searched for: Subject "Tacca" Remove constraint Subject: "Tacca" Start Over. This led the authors to suggest that most bat plants are self-pollinated. This distinctive flowering plant is native to Myanmar (Burma, to us old-timers) and Thailand (Siam, to the really old-timers). Tacca wilsonii Distribution and habitat: Tacca chantrieri grow wild in the tropical forest from the regions of West Africa and Southeast Asia, where they can get as tall as 90cm (35 inch). Journal of natural products 7; Journal of food process engineering 2; Agriculture and natural resources 1; American journal of botany 1; Annals of botany 1; more Journal » Publication Year. Pollinator visitation was infrequent and … A 2005 study done in South Yunnan province, China found that almost nothing visited the flowers of Tacca chantrieri. Please check your email for instructions on resetting your password. Tacca are pollinated by two pollination guilds of female midges: two species of Forcipomyia (Lasiohelea) and Culicoides hinnoi. . The genetic benefits that result from cross‐ vs. self‐fertilization have been widely recognized since Darwin's pioneering studies on this topic (Darwin, 1876; Charlesworth and Charlesworth, 1987a). Demography and evolution in plant populations. Despite the possession of traits commonly associated with fly pollination by deceit, we recorded no flies acting as pollinators of T. chantrieri. Our studies of the floral biology and mating system of T. chantrieri indicate that most seeds produced in populations result from self‐fertilization. Plant materials. Elsewhere, Lamborn and Ollerton (2000) used floral manipulations to investigate the function of the dark central floret in inflorescences of Daucus carota (Apiaceae). Further ANOVA of percentage seed set data by population indicated no significant difference at XTBG (F1,48 = 0.018, P = 0.895 NS, bagged seed set = 48.8 ± 1.83, N = 25, control = 49.1 ± 1.83, N = 25) but significantly more seed set in the control treatment at WEV (F1,44 = 5.16, P = 0.028, bagged seed set = 45.3 ± 3.12, N = 26, control = 56.04 ± 3.57, N = 20). Pollen‐ovule ratios a conservative indicator of breeding systems in flowering plants. Our failure to observe fly pollination in T. chantrieri is unlikely to be the result of a rarity of flies in the vicinity of the populations we investigated. If this is true, why does T. chantrieri maintain a suite of floral traits associated with sapromyiophily? Learn about our remote access options. Predicting mating patterns from pollination syndromes: the case of “sapromyiophily” in Tacca chantrieri (Taccaceae) Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker-like filiform bracteoles. Observations of flowering at WEV indicate that flowers of T. chantrieri begin anthesis around 1000 to 1100 hours and last for 2 d. Inflorescences generally flower for 6–14 d (10.1 ± 0.3, mean ± SE, N = 50) and produce 1–4 (1.7 ± 0.78, N = 100) flowers each day. We performed two pollination treatments on a single inflorescence of 20–26 randomly selected individuals of T. chantrieri at the WEV and XTBG populations to examine the capacity for autonomous self‐pollination and therefore the importance of insect visitors to pollination. The treatments were: (1) open‐pollinated controls and (2) autonomous self‐pollination. If you do not receive an email within 10 minutes, your email address may not be registered, The main objective of our study was to establish whether or not the unusual features of flower and inflorescence morphology in T. chantrieri are part of a syndrome associated with sapromyiophily, as proposed in the literature for Tacca species in general. Li). . All pictures are contributed by our community. Q.-J. It is increasingly difficult to find T. chantrieri in its natural (Annonaceae) in Sri Lanka. We estimated mating patterns in four populations of T. chantieri using 16 open‐pollinated families sampled at random from each population. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. It is distinguished by the following characters: the petioles, peduncles, and flowers are red wine coloured instead of dark purple; the bracts are very similar to T. chantrieri, but the fruits have different intumescent placentas, which fill the fruit cavity; and the … T. chantrieri, an endangered species (Fu and Jin 1992), Fig. Tacca chantrieri has extravagant floral displays and a high investment in reproductive structures that lead to the expectation that it is largely outcrossing (Drenth, 1972; Saw, 1993). Generalization versus specialization in plant pollination systems. We propose several explanations that help to resolve this paradox. Wiley has partnerships with many of the world’s leading societies and publishes over 1,500 peer-reviewed journals and 1,500+ new books annually in print and online, as well as databases, major reference works and laboratory protocols in STMS subjects. Shift towards autogamy in the extremely narrow endemic Aquilegia paui and comparison with its widespread close relative A. vulgaris (Ranunculaceae). - "Predicting mating patterns from pollination syndromes: the case of "sapromyiophily" in Tacca chantrieri (Taccaceae)." Tacca chantrieri has extravagant floral displays and a high investment in reproductive structures that lead to the expectation that it is largely outcrossing (Drenth, 1972; Saw, 1993). A fetid odor occurs in many sapromyiophilous species (Faegri and van der Pijl, 1971; Proctor et al., 1996). Its beautiful inflorescence complete with long purplish filaments 12in long forming a flowing forked tail. We ground seeds in a sodium phosphate extraction buffer (20 mg diethyl‐dithio‐carbamic acid, 10 mg EDTA, 25 mg BSA and one drop of Tween 80 dissolved in 20 ml of 0.05 M sodium phosphate pH 7.0). In our field experiment, the percentage fruit set and seed set did not differ significantly among the three treatments (fruit set: control, 67.8 ± 3.69 [mean ± SE, N = 23]; bracts removed, 65.2 ± 3.74 [N = 23]; staked, 72.7 ± 3.52 [N = 25]; seed set: control, 45.8 ± 3.29; bracts removed, 44.6 ± 2.36; staked, 47.9 ± 2.77; P > 0.1 for all comparisons). in two showy species, Tacca integrifolia Ker Gawl. Nome botanico: Tacca chantrieri. and you may need to create a new Wiley Online Library account. option. The two populations differed significantly in the number of flowers per inflorescence (t = 3.81, P = 0.0001, df = 98) and seed set (t = 1.98, P = 0.03, df = 43). The Black Bat Plant is a very unusual plant from the yam family (Dioscoreaceae), grown for it’s bizarre flowers. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, I have read and accept the Wiley Online Library Terms and Conditions of Use. These traits are all reported in species of Tacca and have been interpreted in the context of the sapromyiophilous syndrome (Drenth, 1972; Saw, 1993). The purpose of the bracts is to protect the flowers while they mature. Contrary to this expectation, populations were … Evaluation of horticultural traits and seed germination of Tacca chantrieri ‘André. Proceedings of the Royal Society B: Biological Sciences. Experimental assessment of the functional morphology of inflorescences of. During flowering, the most conspicuous features of display in T. chantrieri are the large, purple involucral bracts and long, filiform bracteoles (Fig. More Information . These filaments seem to bear resemblance to tiger wiskers and hence its name Tiger Wiskers. Selfing rates estimated in four populations using allozyme markers averaged 0.86 (range 0.76–0.94), thus corroborating this inference. Finally, we estimated mating patterns (see later) in four populations occurring at the following locations: Bubeng dipterocarp forest (Shorea wangtianshunea, Dipterocarpaceae) in Mengla County (BB); Wild Elephant Valley in Jinghong County (WEV); Menglun nature reserve in Mengla County (ML); protected forest close to the Mengyang‐Menglun highway (MY), 43 km from Mengyang in Jinghong County (Fig. EUR 29,99 a EUR 129,00. Pollen loads on stigmas indicated autonomous self‐pollination, some of which occurred prior to flower opening. We recorded the total number of flower visitors per individual and the number of flowers visited. Tacca chantrieri is a perennial plant belongs to Taccaceae family that has the potential to be marketed as an ornamental plant due to its unique shape and dark color inflorescence. Jack (Dioscoreaceae) by Female Ceratopogonid Midges (Diptera: Ceratopogonidae) However, when fruits were mature 4 mo later, samples sizes were reduced because of damage by elephant trampling. 3). An alternative possibility is that the bracts and bracteoles function in seed dispersal and serve to attract dispersal agents to plants. With spatial and temporal variation in pollinator service, even low levels of fly‐mediated outcrossing may be sufficient to maintain the sapromyiophilous syndrome, if the fitness benefits of outcrossed progeny are sufficient to outweigh the costs of selfing and investment in display. © 2005 Wiley It is unlikely that the syndrome is maintained simply to attract flies for the purpose of facilitated intra‐ and interfloral selfing. These features have been assumed to function as a ‘‘deceit syndrome’’ in which reproductive structures resemble decaying organic material attracting flies that facilitate cross-pollination (sapromyiophily).
