The Relation between the Patterns of Cytomixis and Variation of Chromosome Numbers in Pollen Mother Cells of Jimsonweed ( Datura stramonium L.)

Cheng Kuo-chang, Yang Qing-lan and Zheng Yong-ren   

Abstract: The phenomenon of cytomixis is a general occurenee in the pollen mother cells (PMCs) of certain angiosperms. Recently, we found this phenomenon also occurred in jimsonweed. According to our observations and a test of chi-square, it has been shown that the discrepancies between the patterns of intercellular chromatin migration and the variation of chromosome numbers in the PMCs of jimsonweed, as well as rye, are not significant. It means that the patterns of intercellulr chromatin migration and the variation chromosome numbers are related to each other.
