Flower Morphology, Fruit Set and Fruit Drop in Some Ber (Zizyphus Mauritiona Lam.) Cultivars·

Abstract

The study was conducted on seven ber cultivars i.e. Seb, Go1a, Mundia, Jogia, Aliganj, Ponda and Ilaichi. The anthesis occurred from 7.30 A.M. to 9 A.M. in all the cultivars except Gola and Mundia in which it took place between 12 noon to 1.30 P.M. The dehiscence was completed in an hour after anthesis. Receptivity of the stigma was maximum on the day of anthesis. Fruits did not set when flowers were covered. Open pollination by the insects was found to be necessary. Fruit drop was maximum during a fortnight after set in all the cultivars except in Ilaichi in which it was maximum one month after set.
