Development of male gametophyte of Platycladus orientalis from dormant period to pollination
摘要
Abstract
Morphological indexes of microstrobilus of Platycladus orientalis (Linn. ) Franco from dormant period to pollination in Mountain Tai were studied using conventional paraffin slice. The results showed that; (1) Morphological changes; the front-end of the microstrobilus turned light brown, and the P. Orientalis entered into dormant period, which lasted from Oct. 22 to the middle of Feb. Next year. The dormant period was over on Feb. 27, and microsporangium developed in microstrobilus. On Mar. 11, the microstrobilus cracked and pollen dispersed. After pollination, the microstrobilus abscised. (2) Development of the male gametophyte: On Oct. 25, sporogenous cell produced microspore mother cell by mitosis in microsporangium. Meanwhile, microspore mother cell arranged densely. In dormant period, microspore mother cell produced microspore by meiosis. On Feb. 27, microspore developed into mononuclear pollen grain. On Mar. 11, mononuclcar pollen grain developed to matured pollen grain.关键词
