A note on the development of embryo-sac and endosperm in Alangium chinense Harms






Bull Bot Soc Bengal 3(1): 11-15

A note on the development of embryo-sac and endosperm in Alangium chinense Harms

The ovary is inferior and bilocular with 2 pendulous anatropous ovules, 1 in each cell. There is a single massive integument, the inner epidermis of which forms the integumentary jacket layer. The nucellar cells are ephemeral but the hypostase tissue connected with the conducting strand is observed in the ovule. A single hypodermal archesporial cell is differentiated which divides into a primary parietal cell and a megaspore mother cell. A normal linear tetrad of 4 megaspore cells is observed. The development of the embryo-sac is of the normal type. Endosperm formation is cellular from the very start.
