摘要:
以菜用大豆品种绿领95-1为试材，研究外源亚精胺(Spd)对NaCl胁迫下菜用大豆植株不同时期叶片多胺含量、膜脂过氧化、渗透调节物质含量等的影响。结果表明，外施Spd显著提高NaCl胁迫下菜用大豆叶片中的游离态腐胺(Put)、亚精胺(Spd)和精胺(Spm)含量；NaCl胁迫下外施Spd的菜用大豆植株叶片超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)和抗坏血酸过氧化物酶(APX)活性均显著高于对照植株， O-2· 产生速率及丙二醛(MDA)含量显著低于对照，植株膜脂过氧化轻于对照；外施Spd植株叶片可溶性糖、可溶性蛋白质含量均显著高于对照。因此，亚精胺在提高菜用大豆耐盐性方面具有重要作用。
