Cytochemical features of self pollination in French bean


, : Cytochemical features of self pollination in French bean. Genetika i Selektsiya 18(5): 400-408

In an analysis of the chemical composition of the stigmas and pollen of Amboy grown in the greenhouse and Zarya grown in the field, flowers and flower buds were studied at different stages of development. For pollen germination, starch hydrolysis was necessary. In the course of pollen maturation, content of cytochrome oxidase and IAA fell. The stigmas formed a secretion of a lipid nature which increased in the course of stigma maturation. This secretion stimulated pollen germination in vitro.
