叶绿体基粒

结果证明，叶绿体基粒结构与捕光Chla/b蛋白质含量正相关，它并非为光合作用基本过程的进行所必需。

The results show that the grana stacking of chloroplast is closely related to the quantity of the light-harvesting chl a / b protein , and is not essential for photosynthesis process .

The results showed that in normal growth conditions , the grana lamella in cucumber seedlings leaves were arranged regularly with more grana , chloroplast structure and the whole membrane system was complete .

冷胁迫导致叶绿体结构变形，基粒片层松散无序，叶绿体膜受到严重损伤，冷胁迫后受伤的膜系统不能立即修复，反而受损伤程度加重。

The chloroplast structure were changed , the grana lamella become loose and disorder under cold stress , and the chloroplast membrane was injured seriously under cold stress . Furthermore , the damage to membrane system was increased instead of repaired .

与有毛黄瓜相比，无毛黄瓜光合机构的结构较简单，叶肉细胞内叶绿体数量少，叶绿体内基粒数和基粒片层数少。

Compared with that of normal cucumber , the structure of photosynthetic apparatus in glabrous cucumber was simple with less numbers of chloroplast and grana as well as the grana lamellae .

较高浓度的氯化铜溶液（50ppm）处理可破坏叶绿体的膜系统，使叶绿体基粒垛迭减少，排列不规则。
