| 摘 要： | 试验研究了锌胁迫对甜瓜幼苗生理活性的影响。结果表明:随着锌浓度的增加,POD、SOD、CAT活性先上升后下降;MDA含量呈逐渐上升趋势;叶绿素含量呈逐渐下降趋势;在Zn离子浓度较低时(50 mmol/L)对甜瓜的影响较少,与对照间无差异,而当Zn离子浓度大于100mmol/L时,Zn离子对甜瓜的毒害较大。

| Abstract: | Experiment was carried out on influence of Zn stress on physiological characteristics of melon.The results showed that with the increase of Zn stress concentration,the activities of peroxidase(POD),supe-roxide(SOD) and catalase(CAT)all first increased and then decreased.The content of malondialdehyde(MDA)increased continually;The content of chlorophyll decreased with the increase of the treated compound.When the Zn ion concentration was low(50 mmol/L) less impact on the melon and no difference with contral,... |
