A series of studies, recently reviewed, has established that approximately 60% of the structural genes which are expressed in the sporophytic portion of the angiosperm life cycle are also expressed and exposed to selection in the pollen. Given the ha

The present research is aimed at investigating if the stylar activation phenomenon varies according to the type of pollen applied. Through electrophoretic analysis of the newly formed proteins of the style ahead of the pollen tubes we determine the s

Pollinations were made on either the tip or the basal portions of the stigmatic surface in Dianthus chinensis. These two treatments provided, respectively, either good or modest opportunity for pollen tube competition. The pollen used came from a sin

Both internal anatomy and external morphology ofthe mature pollen grain of Nicotiana slata have been studied, together with pollen activation and tube emergence and its cytological zonation. A peculiar feature of mature pollen is the occurrence in th

The conventional hypothesis of gametophytic self-incompatibility in the angiosperms involves one to four multiallelic incompatibility loci and the positive inhibition of incompatible pollen tubes. However, this concept does not accommodate recent exp

SUMMARY By delaying pollination with flowers of Petunia hybrida for up to 5 days, the viability of aged pollen and the numbers of seeds resulting from crosses declined with aging of either staminate or pistillate parent. In the resulting generation,
