Cell Development in the Young Seed of Two Inbred Lines of Pearl Millet, Pennisetum Americanum.

Abstract

Rate of cell development in embryo and endosperm during the 1st 4 days after pollination was similar in 2 lines of P. americanum under field conditions. 1st division of the endosperm nucleus was complete within 6 h after pollination. Synchronous mitoses, the mitotic cycle, divisions within the embryo and the endosperm and embryo volume increases are described.
