The pollination of Trimenia moorei (Trimeniaceae): floral volatiles, insect/wind pollen vectors and stigmatic self-incompatibility in a basal angiosperm.
Trimenia moorei (Oliv.) Philipson is an andromonoecious liane with >0.40 of the total flower buds maturing as bisexual flowers. Male and bisexual flowers are strongly scented with pollen, anther sacs and receptacle scars testing positively for volatile emissions. Scent analyses detect over 20 components. The major fatty acid derivative is 8-heptadecene, and 2-phenylethanol dominates the benzeno...
متن کاملPollen Germinability and Cross-Pollination Success in Persian Cyclamen (Cyclamen persicum Mill.)
Low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. This study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. In order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...
متن کاملInfuence of pollen source and pollination Time on Furit set of Ferragness Self-incompatibility Almond
Different experiments have showed that interruption in pollination is an important problem in most almond orchards.Asmost of the almond cultivars are self-incompatible,pollination cannot be performed desirably and as a result a failure in almond yield is occurred.Thus under this circumstance,determination of selective cultivars compatibility and choosing appropriate pollinizers are so important...
متن کاملPollination Reservoirs in Lowbush Blueberry (Ericales: Ericaceae)
Pollinator-dependent agriculture heavily relies upon a single pollinator-the honey bee. To diversify pollination strategies, growers are turning to alternatives. Densely planted reservoirs of pollen- and nectar-rich flowers (pollination reservoirs, hereafter "PRs") may improve pollination services provided by wild bees. Our focal agroecosystem, lowbush blueberry (Vaccinium angustifolium Aiton),...
متن کاملStigmatic fluid aids self-pollination in Roscoea debilis (Zingiberaceae): a new delayed selfing mechanism.
BACKGROUND AND AIMS Delayed selfing is the predominant mode of autonomous self-pollination in flowering plants. However, few delayed selfing mechanisms have been documented. This research aims to explore a new delayed selfing mechanism induced by stigmatic fluid in Roscoea debilis, a small perennial ginger. METHODS Floral biology and flower visitors were surveyed. The capacity of autonomous s...
