| 摘 要： | 以番茄品种“合作908”和“奇达利”为试材,研究了不同浓度(0.1、0.5、1、2、4 mmol/L)水杨酸(SA)诱导盐胁迫下对番茄幼苗生理指标的影响.结果表明:SA可有效抑制叶绿素含量的减少；增强叶片过氧化物酶( POD)、过氧化氢酶(CAT)的活性；降低膜脂过氧化产物丙二醛(MDA)含量和质膜透性,缓解了盐胁迫对幼苗生长的抑制.SA的最佳诱导浓度为1mmol/L.

| Abstract: | Taking'Hezuo908'and 'Qidali' tomato as test material,effect of different concentrations of salicylic acid(0.1,0.5,1,2,4 mmol/L)under salt stress-induced on physiological indices of tomato seedlings were studied.The results indicated that the best treatment concentration of SA was 1 mmo1/L.SA restrained the decrease of chlorophyll and significantly enhanced peroxidase(POD),catalase(CAT)and other plant cell protective enzyme activity of leaf and reduce the content of malondialdehyde(product of membrane lipid ... |
