摘    要:重金属镉处理烟草植株引起叶片光合强度降低;处理离体叶绿体引起光合电子传递受阻,光化学活性降低。在经过电镜分析了镉对光合器超微结构的影响后认为,镉破坏光合膜结构.这可能是引起光合强度降低的主要原因之一。

关 键 词:光合电子传递,叶绿体超微结构,光合强度,镉处理

Abstract:Treatment of intact tobacco plant and isolated chloroplasts with cadmium decreased the photosynthetic intensity of the leave, inhibited the photosynthetic electron transport of the chloroplasts and also decreased the activity of photosynthetic chemistry. The ultrastructures of chloroplasts treated with Cd were also studied. The result showed that Cd might cause the damage of photosynthetic membrane,this might be the main reason decreasing the photosynthetic intensity of the plant and the chloroplasts treated with Cd.
Keywords:photosynthetic electron transport  ultrastructure of chloroplasts  photosynthetic intensity  cadmium treatment
