Abstract:

以磷效率差异显著的垦鉴27(磷高效型)和丰收25(磷低效型)2个品种为供试材料,采用盆栽控制磷供应水平方法研究了不同基因型大豆各生育时期的细胞膜透性、SOD、POD、CAT活性以及MDA积累状况。结果表明:2种基因型大豆在磷供应充足的情况下,保护酶活性差异不显著;低磷胁迫下,丰收25细胞膜透性大幅度升高,相对电导率升高41.01%,MDA含量增加23.43%,保护酶活性明显下降,SOD活性降低12.52%,POD活性降低24.16%,CAT活性降低31.75%;垦鉴27细胞膜透性稍有增加,相对电导率升高19.39%,MDA含量增加14.11%,保护酶活性略有降低,SOD活性降低4.98%,POD活性降低13.21%,CAT活性降低28.81%。由此说明,垦鉴27可以通过对磷素高效利用,提高保护酶(SOD,CAT和POD)活性降低O2的产生速率,从而降低细胞膜透性,而丰收25这种自我保护能力较差。
