| 摘 要： | 以番茄为试材,研究了低温胁迫下外源钙对番茄幼苗生理生化指标及膜伤害程度的影响。结果表明:喷施钙盐后可以降低番茄幼苗电解质渗透率和丙二醛含量,同时增加番茄幼苗的可溶性蛋白质和可溶性糖的含量,说明钙在番茄幼苗抗冷调控过程中起了重要作用。

| Abstract: | With tomatoes as test materials,studied the exogenous calcium on low temperature stress of tomato seedings physiological and biochemical and the influence of membrane damage degree.The results showed that electrolyte leakage and malondialdehyde(MDA)of tomato could be reduced after spraying calcium salt.At the same time content of soluble protein and soluble sugar content of tomato could be increased.It showed that,calcium could play an important role in controlling cold resistance of tomato seedlings. |
