| 摘 要： | 通过盆栽试验，研究了Cd胁迫对草莓叶片叶绿素含量、光合速率、气孔导度、蒸腾速率和胞间二氧化碳浓度的影响.结果表明,Cd降低草莓叶片中的叶绿素总量，并改变叶绿素a和叶绿素b的比例;Cd降低草莓叶的光合速率和气孔导度，但在Cd胁迫初期，低浓度的Cd对草莓叶的光合速率和气孔导度有促进作用；Cd还降低草莓叶片的蒸腾速率和胞间CO2浓度，其中，胞间CO2浓度的降低幅度相对较小.

| Abstract: | With pot experiment, this paper studied the effects of cadmium stress on the leaf chlorophyll content, photosynthetic rate, stomatal conductance, transpiration rate, and intercellular CO2 concentration of strawberry. The results showed that cadmium reduced the chlorophyll content, and changed the chlorophyll a/b ratio. Cadmium reduced the photosynthetic rate and stomatal conductance, though they were increased by low concentration cadmium at the initial stage of cadmium stress. Cadmium also reduced the transpiration rate and intercellular CO2 concentration, but the decrement of intercellular CO2 concentration was relatively less. |
