| 摘 要： | 以‘丰研2号’茄子种子为试材,分别用0.25mmol·L-1的亚精胺(Spd)和精胺(Spm)引发处理24h后,分别在10、15、25℃条件下进行种子发芽试验,并测定幼苗耐冷性等生理生化指标。结果显示,Spd和Spm处理可显著提高种子在低温胁迫条件下的活力,促进幼苗生长,显著降低了低温胁迫条件下幼苗细胞质膜透性和MDA含量,提高了抗氧化酶(SOD、POD、CAT)活性和脯氨酸、可溶性蛋白质的含量,表明多胺引发处理对提高低温胁迫下茄子种子活力及增强幼苗耐冷性具有重要作用。

| Abstract: | Effects of Spd and Spm treatments on eggplant（Solanum melongena L.）seed vigor and seedling chilling tolerance were studied under chilling stress. Seeds of eggplant hybrid‘Fengyan 2’were soaked with 0.25 mmol • L-1 of Spd and Spm，respectively for 24 h in dark under 10 ℃，15 ℃ and 25 ℃，and the control was not treated with Spd and Spm. The seed vigor indices and seedling chilling tolerance indices between treatment and untreatment were investigated and compared. Results showed that Spd and Spm treatments significantly improved seed vigor and seeding growth，raised the activities of POD，CAT and SOD，increased soluble protein and Pro contents，and decreased membrane permeability and MDA contents. The results suggested that Spd and Spm played a vital role in promoting eggplant seed vigor and seedling chilling tolerance. |
