文摘

In gynodioecious plants females need a reproductive advantage over hermaphrodites. Differences in floral longevity between sexes can provide a reproductive advantage. Stigma and flower lifespan was examined in gynodioecious Geranium sylvaticum. Stigma and flower lifespan are almost twice as long in females as in hermaphrodites.
