Effect of five components (Calcium chloride (CaCl2), Salicylic acid (SA), Abscisic acid(ABA), Spermidine(Spd)) on chilling tolerance in cucumber seedlings was studied. Components (ALA and Spd) which could obviously improve chilling tolerance of cucumber seedlings were selected. Their mechanisms were studied. The results were as follows:
Cucumber seedlings with two true leaves were spread by different concentrations of five components (CaCl2, SA, ABA, Spd and ALA) under low temperature st...
