The Relations Between Chromosome Aberration and the Intercellular Chromatin Migration in Pollen Mother Cells of Vicia faba

Wang Xin-yu and Zheng Guo-chang(Cheng Kuo-chang)   

Abstract: Squash, paraffin section and chromosome banding technique were used to observe the condition of the intercellular chromatin migration (cytomixis) and chromo- some aberration in pollen mother cells (PMCs) of Vicia faba. The following phenomena were found in our experiments; 1. Cytomixis also occurred at synizesis stage. 2. 8.08% of PMCs had a chromosome number deviating from their normal numbers (n=6). 3. The changes in chromosome structure included the chromosomes with a increased or decreased length and chromosome bridges. 4. Appearance of anucleate and binucleate PMCs. Plenty of evidenee shows that the last three phenomena are related to the first one.

Key words: Pollen mother cells, Chromosome aberration, Cytomixis, Vicia faba
