Variation in Anthesis and Pollen Production in Plants

Flowering is of prime importance in plant’s life and in breeding, which determines generation turn over and genetic gain. It has been established that the flowering is under genetic control but highly influenced by the environmental factors. The quantum of flowering and pollen production is inconsistent, abundant in some years and meagre or absent in others at individual and community level, affect the degree of genetic variability in each species. In the present review, information were brought together and evaluated on this subject particularly the regulation of anthesis by temperature, relative humidity and light alongwith the consideration of the role of pollen production in pollination and fertilization.
