Abstract

The present study was conducted to evaluate the differences in photosynthetic parameters and antioxidant enzyme activity among two genotypes of soybean (Glycine max L.) in response to salinity stress. Ten-day-old seedlings, grown hydroponically, were treated with 0, 25, 50, 75, 100, 125 and 150 mM NaCl for 7 days and analysed for the traits as biomarkers for identification of salt-tolerant soybean genotype. It was observed that NaCl stress caused severe impairments in photosynthetic rate, chlorophyll fluorescence and chlorophyll content in both the genotypes, but the damage were much more pronounced in salt-sensitive genotype VL SOYA-47. Moreover, chlorophyll fluorescence measurements showed higher non-photochemical quenching in genotype VL SOYA-47 and lower in genotype VL SOYA-21. The antioxidant enzyme activities (superoxide dismutase, catalase, ascorbate peroxidase and glutathione reductase) was observed much higher in VL SOYA-21 than in VL SOYA-47 at various levels of NaCl treatments. From the results, it could be suggested that VL SOYA-21 is the salt tolerant and VL SOYA-47 is a salt sensitive soybean genotype. The tolerance capacity of VL SOYA-21 against NaCl stress can be related with the ability of this genotype in possessing vital photosynthetic system and ROS scavenging capacity.

中东大豆(Glycine max L.)盐胁迫表型分析
研究了2个基因型大豆(Glycine max L.)光合参数和抗氧化酶活性在盐胁迫下的差异。用0、25、50、75、100、125和150 mM NaCl处理10 d的大豆幼苗,分析其性状,作为耐盐大豆基因型鉴定的生物标志物。结果表明,NaCl胁迫对两种基因型大豆的光合速率、叶绿素荧光和叶绿素含量均造成严重损害,但对盐敏感的VL SOYA-47受到的损害更为明显。此外,叶绿素荧光测量显示,基因型VL SOYA-47的非光化学猝灭程度较高,而基因型VL SOYA-21的非光化学猝灭程度较低。在不同NaCl处理下,大豆抗氧化酶活性(超氧化物歧化酶、过氧化氢酶、抗坏血酸过氧化物酶和谷胱甘肽还原酶)均显著高于大豆大豆47。结果表明,VL SOYA-21为耐盐大豆基因型,VL SOYA-47为盐敏感大豆基因型。VL soy -21对NaCl胁迫的耐受能力可能与该基因型具有重要的光合系统和清除ROS的能力有关。
