Despite the presence of numerous potential pollinators, only a handful of small, stingless bees paid any attention to these obvious floral cues. (d) The infructescence with relatively high fruit set. Despite the presence of numerous potential pollinators, only a handful of small, stingless bees paid any attention to these obvious floral cues. The distribution of Tacca chantrieri (from the website of the Missouri Botanical Garden, www.mobot.org) and the locations of populations investigated in this study in South Yunnan province, China, Reproductive biology of Tacca chantrieri. Ethnobotanical Uses: Edible Plant Parts (Edible Leaves, Edible Flowers) Food (Fruit & Vegetable : Its leaves and inflorescences are used in curries.) and Tacca chantrieri André, demonstrate a very high degree of geograph- ical population stratiﬁcation, consistent with a hypothesis of self-pollination (Zhang et al. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. Tacca chantrieri is a widespread species that occurs in humid tropical regions of south-east Asia. Drenth (1972) and Saw (1993) assumed that Tacca species have the sapromyiophilous syndrome, in which the color and odor of flowers mimic rotting organic material and cross‐pollination is mediated by flies. If this is true, why does T. chantrieri maintain a suite of floral traits associated with sapromyiophily? Despite the functional link between these critical stages of sexual reproduction, few studies of pollination syndromes have simultaneously investigated both processes. Its pollination takes place through small mammals and rodents who eat its fruit. 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. When they split along their sides, numerous 0.5cm (0.25 inch) seeds are revealed embedded in a sticky pulp. Integrating ecological and evolutionary processes in a spatial context.

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. A 2005 study done in South Yunnan province, China found that almost nothing visited the flowers of Tacca chantrieri. Pollinator visitation was infrequent and … Q.-J. Genetic structure and breeding system of a rare understory herb, Dysosma versipellis (Berberidaceae), from temperate deciduous forests in China. We estimated mating patterns in four populations of T. chantieri using 16 open‐pollinated families sampled at random from each population. 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. The … Tacca species produce fleshy fruits that are assumed to be animal dispersed by birds and small rodents (Saw, 1993). Demographic factors and mating patterns in angiosperms. 2f). With a growing open access offering, Wiley is committed to the widest possible dissemination of and access to the content we publish and supports all sustainable models of access. Geographical variation in mating patterns is well known in other species of flowering plants, and in some cases, high selfing is associated with infrequent pollinator service (reviewed in Lloyd, 1980; Barrett et al., 2001). View picture of Tacca Species, Bat Flower, Cat's Whiskers, Devil Flower (Tacca chantrieri) at Dave's Garden. Indeed, several of the vernacular names used for T. chantrieri (“bat plant,” “tiger's whisker,” or “devil flower”) reflect these images. We constrained pollen and ovule allele frequencies to be equal to each other to maximize the accuracy of the mating system estimates. 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. In addition, our study raises several general questions concerning pollination and mating in animal‐pollinated plants. Selfing rates estimated in four populations using allozyme markers averaged 0.86 (range 0.76–0.94), thus corroborating this inference. 1). Floral characters of Tacca chantrieri based on samples from the XTBG population. Indeed, the syndrome could function in other populations of T. chantrieri elsewhere in its range. patterns from pollination syndromes: The case of sapro-myophily 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. 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). Tacca chantrieri André is perennial plant belonging to the Taccaceae family. The leathery capsules about 4cm (1.5 inch) long require up to a year to ripen. Optimality modeling and fitness trade‐offs: when should plants become pollinator specialists? Citation in PubAg 19; Full Text 5; Journal. Instead, our results indicate that populations of this species are predominantly selfing and that flowers have several traits that promote autonomous self‐pollination. 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.) American Journal of Botany JSTOR is part of ITHAKA, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways. Zona geografica: Sud-Est asiatico Asia. Tacca chantrieri: Common Name: Bat flower: Plant Type: Perennial: Mature Size: 36 inches tall, 12 inches wide: Sun Exposure: Partial sun to dappled shade: Soil Type: Fertile, well-drained: Soil pH: 6.1 to 7.5: Bloom Time: Late summer through fall: Flower Color: Black (dark purple), white (Tacca integrifolia)) Hardiness Zones: 9b to 11 : Native Areas: Asia, Australia: … Evolutionary Assurance During flowering, the most conspicuous features of display in T. chantrieri are the large, purple involucral bracts and long, filiform bracteoles (Fig. To date, very limited publication on T. chantrieri are available. Subito a casa, in tutta sicurezza. The treatments were: (1) open‐pollinated controls and (2) autonomous self‐pollination. Maintenance of mixed mating after the loss of self-incompatibility in a long-lived perennial herb. Investment in attractive structures represents an allocation cost that animal‐pollinated plants pay to secure the fitness advantages that accrue from cross‐fertilization (Charlesworth and Charlesworth, 1987b). Wiley has published the works of more than 450 Nobel laureates in all categories: Literature, Economics, Physiology or Medicine, Physics, Chemistry, and Peace.
