南黄大麦是一个新的稳定的突变体。其叶绿体为近似的椭圆形，有双层外被膜，其基质的电子密度低，含有大小不等的嗜锇颗粒、淀粉粒等，基质片层和基粒不发达，并有一个随个体发育而逐渐复杂化的过程，是个体发育重演系统发育在亚显微结构水平上的新证据之一，对叶绿体发育的条件等进行了分析。南黄大麦叶绿体分裂有两种方式：即痕缢法和切割法。对叶绿体分裂的方式、时间、同步性、子叶绿体大小等进行讨论。本文首次全面系统地对叶绿体的分裂过程进行了介绍，并获得了一批亚显微结构方面的电镜照片。
Southern yellow barley is a new stable mutant. Its chloroplasts are nearly oval in shape with a double outer envelope with low electron density of the matrix, osmophilic granules of varying sizes, starch grains, etc., basal lamina and basal grains underdeveloped and one with individual development The progressively more complex process is one of the new evidences that phylogeny of phylogeny reappears on the level of sub-microstructure, and the conditions of chloroplast development are analyzed. Southern yellow barley chloroplasts split in two ways: that marks the law and cutting method. The way of chloroplast division, time, synchronicity, the size of the sub-chloroplast and so on are discussed. In this paper, for the first time, the process of chloroplast fragmentation is introduced systematically and systematically, and a number of submicroscopic SEM images have been obtained.
