| 摘 要： | 本文报道黄芪花药壁的发育及花粉母细胞染色质转移运动的细胞学观察,结果如下:1.花粉发育起源于多孢原细胞。2.花药壁基本上按着单子叶型进行发育。3.花粉母细胞间的染色质转移运动普遍存在于减数分裂过程中的各个时期。它们随时都可进行这种运动,没有时间性与连续性。

| Abstract: | This paper reports cytological observation on the anther wall dev- elopment and the intercellular migration of chromatin substance of(PMC's) of Astragius membranaceus(Fisch.)Bge., the results are as follows: 1. The pollen development orients in the multicellular archesporium. 2. the anther wall development mainly follows the Monocotyledonous type. 3. the intercellular migration of chromatin substances is a general phenomenon in the various stages of (PMCs) meiosis. They move at any times, but without time's interalav and continuity. |
