摘要
通过盆栽方法研究了干旱胁迫下接种泡囊丛枝菌根真菌(VAM真菌)摩西球囊霉(Glomusmosseae)对大豆[Glycine max(L.)Merr.]幼苗叶片质膜抗氧化系统、叶片渗透调节物质含量及叶片色素含量的影响。结果表明,干旱胁迫下,与未接种VAM真菌相比,接种VAM真菌可以缓解因干旱胁迫造成的大豆叶片内超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性的下降,显著提高类胡萝卜素含量,缓解游离脯氨酸(Pro)的积累、提高可溶性蛋白质(SP)含量,提高可溶性糖(SG)的转运速度,抑制叶绿素(Chl)的分解。
The effects of inoculation of vesicular arbuscular mycorrhizal(VAM) fungi Glomus mosseae on plasma antioxidant system,content of smotic regulation substances and pigment in leaves of soybean(Glycine max(L.) Merr.) seedling under drought stress were studied using pot experiment.The results showed that the decrease of superoxide dismutase(SOD),peroxidase(POD) and catalase(CAT) activity caused by drought stress could be released by inoculation of VAM fungi.While the content of carotenoid significantly increased;accumulation of free praline(Pro) decreased,content of soluble protein(SP) increased,and transit of soluble sugar(SG) was speed up;the decomposition of chlorophyll(Chl) was restrained.
