| 摘 要： | 测试不同浓度NaCl和PEG胁迫条件下丝瓜幼苗体内超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)活性及丙二醛(MDA)、可溶性糖(SS)、叶绿素含量的变化情况.结果表明,在两种胁迫处理条件下,三种抗氧化酶活性均高于对照;MDA含量随NaCl处理浓度的增加先上升后下降, PEG胁迫条件下MDA含量随处理浓度的增加而下降;可溶性糖(SS)含量随NaCl处理浓度的增加先上升后下降,随PEG处理浓度的增加明显上升;两种处理条件下叶绿素含量均随处理浓度增加而下降.

| Abstract: | The activity of anti-oxidant enzymes(Superoxide dismutase(SOD),Peroxidase(POD),Catalase(CAT)),parameters of oxidative stress malondialdehyde(MDA),soluble sugar(SS) and chlorophyll content of shoots were investigated in L.cylindrical.The seedlings of L.cylindrical were treated with varying NaCl(0,50,100,150 mmol/L) and PEG(0,10%,15%,20%) stress.The activities of SOD,POD and CAT showed different developing tendencies with the increase of the concentration of NaCl or PEG in shoots of L.cylindrical,but it was h... |
