Meiotic observations of the pollen mother cells of Dimocarpus longan
Abstract：The developed smearing method was adopted to observe the meiosis process of pollen mother cell（PMC）of Shixia longan（Dimocarpus longan Lour.cv.Shixia）in this article.The results showed that：（1）.The meiosis process of longan pollen mother cells were closely correlated with the bud size and the anther color,and the difference in the stages of meiosis existed in the same bud and anther.（2）.There were a series of abnormal phenomena in meiotic division of pollen mother cells such as chromosome fragments,lagging chromosomes,chromosome bridges,asynchronization of chromosomes segregation,micronucleus,deviant tetra and so on.The reason of abnormal phenomena in meiosis of pollen mother cells was analyzed on cytogenetics levels.This research aimed to provide scientific evidence for cytogenetics and breeding of longan varieties.
