Abstract
The effects of exogenous calcium on the physiological responses of cotton seedlings under low temperature stress were studied.The cold-sensitive variety Xinluzao 12 was treated under 5 ℃ stress and spraying CaCl2,Ca(NO3)2,and CaAc2 with the concentrations of 10 mmol/L,15 mmol/L,20 mmol/L,25 mmol/L,and 30 mmol/L,respectively.Different physiological indexes were measured after 3 days.The results showed that the cotton seedlings were significantly hurt after 3 days low temperature stress.CaCl2,Ca(NO3)2 and CaAc2 alleviated the damage of cotton seedlings caused by low temperature stress in extent,but different calcium salts had different concentration,and 20 mmol/L CaCl2 had better effect.Chilling index of cotton seedlings could obviously decrease,relative conductivity and MDA content were inhibited effectually,at the same time the content of osmolytes increased further more,antioxidative enzyme activity increased significantly.Exogenous Ca2+ could significantly alleviated the damage of cotton seedlings caused by low temperature stress.
