Effects of cadmium stress on photosynthetic functions of strawberry.
镉胁迫对草莓光合的影响

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.
