采用细胞学方法对小叶锦鸡儿减数分裂进行了观察,结果表明:①小叶锦鸡儿减数分裂进程有一定的规律,与花蕾大小、花萼形态、花药色泽有密切关系。②所试材料减数分裂染色体行为表现正常,细胞质是同时型分裂。③小叶锦鸡儿减数分裂进程上存在差异,同一植株的不同花蕾花粉母细胞减数分裂时期表现不同步性,同一花蕾的不同花药表现一定的同步性。
The cytological method was used to observe the meiosis of Caragana microphylla. The results showed that: ① The process of meiosis of Caragana microphylla has certain rules, closely related to flower bud size, calyx morphology and anther color. ② The meiotic behavior of the tested material was normal, and the cytoplasm was simultaneously split. ③ The process of meiosis of Caragana microphylla There are differences in the process of meiosis, the same plants at different stages of the flower bud pollen mother cell meiosis at different stages of performance, the same flower buds of different anthers show a certain degree of synchronization.
