2During chilling stress,Ca~(2+)treatment could delay the decrease of the activity of SOD,POD and CAT;And it could delay the decrease of the content of GSH,AsA and Car of the heat-shock-induced cucmber seedings.Therefore it enhanced the antioxydization ability,and reduced malon-diadehyde(product of membrane lipid peroxidation)and cytomembrane permeability of the heat-shock-induced cucmber seedings.

2钙处理能减缓冷胁迫下热激黄瓜幼苗的SOD、POD和CAT的活性以及GSH、AsA、Car的含量下降，因而增强了热激黄瓜幼苗的抗氧化能力，降低了膜脂过氧化产物丙二醛含量和质膜透性；而EGTA处理则相反。

But the EGTA treatment had the opposite effect.(3)During chilling stress,Ca~(2+)treatment could delay the decrease of K~+,Mg~(2+), soluable protein content and the increase of Ca~(2+)content;And it could enhance the increase of soluable sugar,free amino acid,proline,heat stable protein and Na~+ content of the heat-shock-induced cucmber seedings.Then it enhanced the osmoregulation ability and delayed the decrease of water potential of the heat-shock-induced cucmber seedings.But the EGTA treatment had the opposite effect.

3钙处理能减缓冷胁迫下热激黄瓜幼苗的可溶性蛋白质、K~+、Mg~(2+)含量的下降以及Ca~(2+)含量的上升，增强可溶性糖、游离氨基酸、脯氨酸、热稳定蛋白和Na~+含量的上升，增强了热激黄瓜幼苗的渗透调节能力，从而缓解了低温下水势的下降；而EGTA处理则相反。
