High male fertility in males of a subdioecious shrub in hand-pollinated crosses [PDF]
AoB PLANTS, 2015 Abstract Female reproductive success in females versus hermaphrodites has been well documented. However, documenting a potential advantage in male fertility of male versus hermaphrodite individuals in subdioecious species is also essential for understanding the evolutionary pathway toward dioecy from hermaphroditism via gynodioecy ...

Adaptive Significance of Flexistyly in Alpinia blepharocalyx (Zingiberaceae): A Hand-pollination Experiment [PDF]
Annals of Botany, 2006 Flexistyly is a sexual dimorphism where there are two morphs that differ in the temporal expression of sexual function and also involve reciprocal movement of the stigmatic surface through a vertical axis during the flowering period. The adaptive significance of flexistyly has been interpreted as a floral mechanism for outcrossing, but it may also ...

MORPHOLOGICAL AND PHYSILOGICAL STUDIES ON FLOWERING, POLLINATION AND FRUITING OF “PICUAL” OLIVE TREES II- EFFECT OF SELF, OPEN, AND CROSS POLLINATION ON FRUIT SET, FRUIT DROP AND FRUIT CHARACTERISTICS [PDF]
Journal of Plant Production, 2002 The influence of self, open and cross pollination (with two pollinizers, i.e. Kronaki and Coratina olive cvs.) on fruiting of Picual olive trees were studied during 1997 and 1998 seasons under Giza conditions.
