吸湿—回干处理降低番茄种子电解质渗漏的机理研究

对吸湿－回干处理降低番茄种子电解质渗漏的机理进行了研究，结果表明，吸湿－回干处理降低番茄种子电解质渗漏的效应产生于吸湿阶段。随吸湿时间延长，电解质渗漏下降，而ＳＯＤ、ＣＡＴ活性上升。mRNA和蛋白质合成抑制对剂电解质渗漏下降与ＳＯＤ、ＣＡＴ活性上升均无抑制作用，表明吸湿处理降低电解质渗漏、提高ＳＯＤ、ＣＡＴ活性的作用mＲＮＡ和蛋白质合成无关，吸湿和吸湿－回干处理后Ｋ３Ｆe(CN)6还原活显著下降，表明的生理生化状态发生了某种变化。

Research on mechanism of hydration-dehydration treatment to reduce electrolyte leakage of tomato seeds

It was investigated that mechanism of hydration-dehydration treatment to reduce electrolyte leakage of tomato seeds.The results showed that effect of hydration-dehydration treatment to reduce electrolyte leakage created in the hydration stage.When the hydration time increased,leakage of electrolyte was reduced,but activity of SOD,CAT was enhanced.The reduction of electrolyte leakage and enhance of SOD,CAT activity were not inhibited by the synthetic inhibitors of mRNA and protein,the fact proved that the effects of hydration treatment to reduce electrolyte leakage and to enhance SOD,CAT activity were not related to mRNA and protein synthesis.After hydration or hydration-dehydration treatment,significant reduction of activity of ferricyanide reduced demonstrated that the physiological and biochemical state of membrane were changed by the hydration or hydration-dehydration treatment.
