摘要/Abstract

摘要： 板栗(Castanea mollissima Bl. ) 短雄花序发育过程中, 花序上部变黄, 弯曲, 最后枯死脱落,
而基部花序正常发育。利用透射电镜观察花序上部发育中的细胞超微结构发现: 细胞呈现有序的死亡变化,
细胞核内发生染色质凝聚, 继而核仁消失, 核质降解, 核膜破裂, 核解体; 液泡内吞现象明显, 形成很多
小液泡; 叶绿体和线粒体也逐渐解体; 花序上部衰亡过程中所有细胞器在膜包裹下有序地降解, 表现出植
物细胞程序性死亡的典型形态学特征。

Abstract: During the development of short catkinsmutant, the upper parts became yellow, curved, and
finally dropped off gradually, while the basal catkins still developed normally. The ultrastructure changes of
cellswere observed during upper naturally degradation by using transmission electron microscope. The results
exhibited orderly changes in death: the nucleus showed chromatin condensation, the nucleolus dissolved, kar
yop lasm degraded, the karyotheca burst and the nucleus disintegrated, the vacuole happened distinct swallow,
and some formed into many small vacuoles, the chlorop last and mitochondrion disintegrated gradually. The
morphological changes during the death of all the organelleswithin the cell showed the typ ical features of p ro
grammed cell death.

Key words: Chestnut, Short catkin, Ultrastructure, Programmed cell death
