| 摘 要： | 对贮藏中福桔果皮细胞超微结构的观察表明,果实成熟即衰老的开始.刚采收的果实,果皮细胞中已看不到核糖体、内质网和高尔基体.叶绿体的基粒、基质片层结构基本消失,脂类小体取而代之,数量增多.最后叶绿体完全转变成有色体.线粒体的衰老发生较迟.采后1-2个月,细胞中结构完整的线粒体数目不断减少.细胞核在衰老过程中变化不大.贮藏150天后从桔水(浮皮)果实取样制片,还能看到细胞核、核仁、线粒体及有色体.

| Abstract: | An Observation on the cell microstructure of Fuju pericarp during storage stage showed that the fruit ripened as the cell senescence as well.As soon as the fruit was picked, the erdoplasmic reticulum,ribosomes and golgi complex were not found.At the same time the thylakoid structure had disappeared and the fat globules were growing more and more in number and filled in the chloroplast.At last,chloroplast changed into chromoplast and ex- isted with the chromoplast through all storage stage.The mitochondria senescence occured after storing 1 to 2 months and the number of the mitochondrion which had perfect structure was decreasing.The nucleus had only a little change in senescence stage.After storing 150 days,taking a sample from the granulation(rind puffing)fruit,the nucleus,nucleolus, mitochondrion and chromoplast could also be seen. |
