Abstract: With pot experiment, this paper studied the effects of cadmium stress on the leaf chlorophyll content, photosynthetic rate, stomatal conductance, transpirationrate, 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.
