Abstract:
Amaranthus tricolor was used as the material，effects of calcium gluconate on the chlorophyll content，photosynthetic parameters of Amaranthus tricolor seedlings under chloride stress were studied.In order to relief the chloride stress of plant production by using calcium gluconate.The results showed that different concentrations of calcium gluconate all could decrease the inhibition of chloride stress on Amaranthus tricolor seedlings growth.The calcium gluconate decreased amplitude reduction for chlorophyll content in different times.All of the treatments applied calcium gluconate increased LAI significantly higher than CK.Pn，Gs，Tr and Ci of Amaranthus tricolor seedlings showed downtrend under chloride stress,while calcium gluconate reduced the decreasing amplitude，maintained Pn a high level.
