摘要:
为探讨西瓜抗逆性及其丰产人工栽培技术，通过PEG 6000和0.1 mol?L-1Nacl处理分别模拟干旱和盐胁迫，并测定其可溶性蛋白质和可溶性糖的含量变化来对西瓜幼苗在干旱、盐逆境交叉适应的反应机制进行研究。结果表明：西瓜在经过单一盐胁迫后，其可溶性蛋白质含量明显下降，可溶性糖的含量明显增加；并且在干旱-盐交叉逆境中可溶性蛋白质含量下降幅度有所减小，可溶性糖的含量增加幅度有所提高。因此，可以初步断定，干旱预处理可以提高西瓜幼苗的耐盐性。
Abstract:
In order to study the stress resistance and high yield cultivation techniques of atermelon,drought salt stress was simulated by the treatments of PEG 6000 and 0.1 mol?L-1NaCl，the change of the soluble protein and sugar were measured to study the reaction mechanism of watermelon seedlings in cros sadaptation.The results showed that the soluble protein content of  atermelon seedlings decreased and the soluble sugar content increased significantly in a single salt ess，and the two indicators increased in the cross-adaptation of drought salt stress.Therefore,it was initially concluded that drought pretreatment could improve the salt tolerance of watermelon seedlings.
