Abstract:
Soil salinization has caused salt damage to crops in greenhouse.Taking cucumber as material，the effects of different concentrations of calcium (Ca2+) (0，20，40，60 mmol/L CaCl2) on the osmotic regulation substance of growth，antioxidant system and photosynthetic characters of cucumber treated with 100 mmol/L NaCl were studied.The results showed that the POD and SOD activity by 20 and 40 mmol/L CaCl2 treatments were lower than CK treatments，but the rate was lower than 10％，relative leaf electrical conductivity，the degree of leaf damage，and leaf MDA content were lower than CK treatment by 20 and 40 mmol/L CaCl2 treatments，and whose soluble sugar content were also higher than CK treatment.Supplying Ca2+ could reduce the photosynthetic indices，and supplying 20 mmol/L CaCl2could reduce water use efficiency.So supplying 20 mmol/LCaCl2 could relieve salt damage to cucumber seedlings，increased the cucumber salt tolerance.
