Abstract
The seed germination experiments and water culture were conducted to study the effects of p-hydroxybenzoic acid and salicylic acid on the cucumber seed germination and the enzyme activities in its seedling under salt stress. The results indicated that p-hydroxybenzoic acid and salicylic acid could increase the germination percentage, germination index, vigor index and the activities of PPOD in cucumber embryo root and embryo bud. The effect of p-hydroxybenzoic acid on seed germination was better than that of salicylic acid. Activities of membrane-profective enzymes in seedling such as SOD, POD and PPOD were promoted. Emzyme activities under the treatment of p-hydroxybenzoic acid were lower than that under salicylic acid. Therefore the injuries caused by salt stress to cucumber seed germination and seedling grouth were mitigated and the salt-tolerance of cucumber was raised by exogenous p-hydroxybenzoic acid and salicylic acid.
