tacca chantrieri pollination

We photographed all types of flower visitors, and voucher specimens of insects are preserved in the insect collections of XTBG. In some contemporary populations, the syndrome could be selectively neutral, and developmental constraints may have prevented significant evolutionary modifications. Contrary to this expectation, populations were highly selfing. 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). You searched for: Subject "Tacca" Remove constraint Subject: "Tacca" Start Over. This confirms that autonomous self‐pollination prior to flower opening produces a significant quantity of seed. Working off-campus? These include dark flowers and bracts, motile filiform appendages, a trap mechanism involving the stamens and stigma acting as a hood and the absence of nectar. For terms and use, please refer to our Terms and Conditions Shift towards autogamy in the extremely narrow endemic Aquilegia paui and comparison with its widespread close relative A. vulgaris (Ranunculaceae). We estimated mating patterns in four populations of T. chantieri using 16 open‐pollinated families sampled at random from each population. 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. We investigated pollination and mating in Tacca chantrieri … However, under current ecological conditions in southwest China, the syndrome may have little utility, perhaps because of scarce pollinator service. (c) A cross‐section of the flower illustrating the close proximity of the stigma and anthers. 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). Nome comune: pianta pipistrello o fiore del diavolo. 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. This work was funded by NSFC grant 30225007 to Q.‐J. Perhaps T. chantrieri produces compounds attractive to flies but not perceptible by humans, as is the case in the fly‐pollinated Asarum (Proctor et al., 1996). Two days prior to anthesis, the flowers were emasculated to prevent prior self‐pollination. . The … T. Reproductive Biology of Two Sympatric Species of Apparently, this has not occurred in T. chantrieri despite mechanisms for autonomous selfing and the low pollen : ovule ratio of the species. Tacca chantrieri, or the black bat plant, grows from underground rhizomes; and produces large-green leaves and long-stemmed flowers.The leaves can be as long as 15 inches. bat pollination: Fledermausblume {f} black bat flower [Tacca chantrieri, syn. Pollen loads on stigmas indicated autonomous self‐pollination, some of which occurred prior to flower opening. Visualization and interpretation of plant isozymes. When flowers were emasculated just before opening, they produced 42.3% ± 4.1 fruit set and 28.4% ± 3.24 seed set. 2a, b). Tacca ampliplacenta 517 American Journal of Botany 92(3): 517–524. We used a haemocytometer to estimate pollen production per flower following methods in Dafni (1992).
