The Character of Anther Development of Impatiens balsamina
摘要
Abstract
The anther development of the Impatiens balsmina displayed some special characters. In sporogenous cell stage, there are some large sporogenous cells, containing density cytoplasm, locating in the central of anthers. The cells of anther wall contain less cytoplasm which makes both distinguish. In the stage of microspore mother cell, the anther wall consists of 6 layers of cells, but the limit line is not clear between the cells. The tapetal cells begin to display the degeneration at this time. In tetrad stage, the tapetal cells degenerate further as the cells become small. The mature anther wall consists of four layers of cells:one layer of epidermis, two layers of endothecium, and one layer of middle layer. The special characters of tapetal cells of Impatiens balsamina were discussed.关键词
