| 摘 要： | 以中华猕猴桃36号为试材,研究了猕猴桃不同部位果肉叶绿体的结构特征并与叶片叶绿体做比较。结果表明,猕猴桃外果肉、中果肉和果心均存在具一定片层结构和淀粉粒的叶绿体。果肉叶绿体的基粒垛数量和基粒类囊体数目都远小于叶片叶绿体;外果肉叶片叶绿体片层似纬线平行排列,而中果肉和果心片层结构在叶绿体内弯曲扭转,排列不整齐;猕猴桃外果肉、中果肉和果心叶绿体都含有淀粉粒,但数量和体积都小于叶片叶绿体;这些观测结果为研究猕猴桃果实的光合特性提供了依据。

| Abstract: | In this work the structure of kiwifruit (Actinidia chinensis Planch. Var.36) chloroplasts which are in pericarp, mesocarp and core have been viewed by transmission electron microscope, and drop gradually from pericarp to core. From lamellae arrangement it can be seen that the pericarp chloroplasts consist of parallel lamella membrane structure, however, in the mesocarp and core, the lamella membrane is distorted. It is possible attributed to the light scarcity and low pH Volue. The chloroplasts in pericarp, mesocarp and core all contain starch granules which may be from kiwifruit photosynthesis, but the size and numbers are less than those of lesves. |
