Studies on Meiotic Behavior of Pollen Mother Cells of bitter gourd (Momordica charantia L.)
摘要
Abstract
Meiotic behaviors of pollen mother cells (PMCs) of bitter gourd (Momordica charantia L. ) were characterized. It was found that the pollen mother cell of bitter gourd revealed a simultaneous cytokinesis with unsynchronized phenomenon in meiotic division. Nucleolus disappeared gradually from prophase I to metaphase I, reappeared at prophase II and then disappeared. Chromosome became more and more identifiable from prophase I to metaphase I, and illegible at telophase I with unwinding. Moreover, multi nucleoli was investigated in prophase I and prophase II. Frequent polyads were observed in this study, which was likely related to the weather adversity and unsynchronized phenomenon in meiotic division.关键词
