盐胁迫对尼日利亚茄子与普通茄子幼苗生理生化指标的影响

通过盆栽NaCl盐胁迫试验,测定了在不同盐浓度条件下尼日利亚茄子和对照品种黑将军的叶片MDA、脯氨酸、可溶性蛋白、可溶性糖含量及叶片主要保护性酶活性。结果表明,在各盐胁迫浓度下,尼茄叶片的MDA含量小于对照品种,且增幅小于对照品种。可溶性糖、可溶性蛋白、脯氨酸等含量以及SOD、POD两种主要保护酶活性均高于对照品种。在盐胁迫过程中,可溶性蛋白、脯氨酸含量及POD活性的增幅显著大于对照品种。表明尼日利亚茄子的耐盐能力要优于对照品种。

Effect of Salt Stress on Physiological and Biochemical Indexes of Nigeria and Common Eggplant

With pot culture,this paper studied the effects of NaCl stress on contents of MDA,proline,soluble protein and the protective enzyme activities,in Nigeria eggplant leaves.Under salt stress,MDA content in leaves of Nigeria eggplant NE(Nigeria eggplant)was lower than that of Lu eggplant LE(Lu eggplant),and increase amplitude of MDA in leaves of NE were more slowly than those of LE.While the contents of soluble sugar,proline,chlorophyll,soluble protein and activities of POD and SOD were higher than those of LE....
