摘要:
用镉处理离体的烟草叶片,0.005mmol/L镉处理就引起光合速率降低,0.027mmol/L镉处理引起叶绿素含量下降,0.1mmol/L镉处理引起膜透性增加,随着处理浓度的增加及处理时间的延长,光合速率、叶绿素含量下降程度增加,膜受损程度也增加,而呼吸速率则呈现出降低-增加-降低的变化。
关键词:  镉处理  细胞膜透性  净光合速率  喑呼吸速率  叶绿素含量

Abstract:
Isolated tobacco leaves were treated with cadmium, the treadment of 0.005mmolCd/L caused the decreasing of photosynthetic rate, 0.0275 mmolCd/L resulted in decreasing of chlorophyll content and 0.1 mmolCd/L cased the increasing of cell membrane permeability. As the increament of Cd concentration and the duration of treatment, the photosynthetic rate and chlorphyll content decreased further. the damaging degree of membrane increased, while the variation Of respiratory rate appeared decreasing-increasing-decreasing.
Key words:  cadmium treatment  cell membrane permeability  net photosynthetic rate  dark respiratory rate  chlorophyll content
