Effects of Salt Stress on Microstructure and Ultrastructure of Glycophyte

综述了国内外关于盐胁迫对甜土植物营养器官细胞显微和超微结构影响的研究进展。长时间的盐胁迫会影响植物的形态建成,使植物的营养器官表现出特有的适应盐渍环境的特征,如叶片肉质化、栅栏组织发达、贮水细胞发达等;叶绿体和线粒体的膜结构被破坏,同时细胞质中出现体积较大的液泡等。

The recent advance studies of effects of salt stress on microstructure and uitrastructure of gly. cophyte at home and abroad were analyzed in this paper.The salt stress for long time could affect plant structural formation, and make nutritional organs of plant perform the characters to be suited for salt environment, such as well - developed water - storing tissues and flourishing palisade tissues in leaves; the membrane of chloroplasts and mitochondrium are destroyed, many big vacuoles appeared in cell material and so on.
