以枳壳、枳橙、纽荷尔、山下红、沙田柚为试材,应用JEM-1010型透射电镜观察研究了不同水分胁迫下柑橘叶片和根系细胞超微结构的变化.结果表明,柑橘叶肉细胞及叶绿体超微结构随水分胁迫强度的增加而受损加剧.在正常灌水条件下,叶片结构完整,叶绿体片层排列均匀、整齐;60%土壤含水率处理下,枳橙和枳壳叶片大部分细胞刚开始质壁分离,但纽荷尔、山下红、沙田柚大部叶肉细胞已经开始质壁分离,叶绿体变形,片层紊乱,排列发生变化,淀粉粒数量减少;40%土壤含水率处理下,绝大部分叶片细胞已经质壁分离,叶绿体形状发生变化,结构被破坏,基粒片层排列紊乱;20%土壤含水率处理下,枳橙、枳壳叶片绝大部分细胞已经...

The effect of water stress on Citrus leaf and root cell ultra-structure, by using Shatian pomelo, Yamasitaka, Newhall orange, Citrange and Trifoliate as materials, was studied through JEM-1010 （LI-COR, Lincoln, Nebraska 68504, USA）. The result showed： water stress could significantly affect root, leaf and chloroplast ultra-structure. The damaged degree of ultra-structure is increased by water stress. Under normal water condition, the cell structure of root and leaf were in good shape, the typical convex lens were composed of alternately arra...
