| 摘 要： | 用液培法以4个不同磷效率的大豆基因型为材料,对其在缺磷胁迫条件下的主根长、根冠比、光合速率及抗衰老能力进行了研究。结果表明:耐低磷主要表现是刺激根的伸长,与磷低效基因型相比,磷高效基因型的主根长、根冠比增长比较明显;磷高效基因型的光合能力和生物膜的抗氧化能力都明显高于磷低效基因型。

| Abstract: | Four soybean genotypes with different phosphorus (P) efficiency were studied in main root length, root/shoot ratio, photosynthetic rate, chlorophyll content and the ability of resistance to senility in solution culture under P deficiency stress. Results showed that P deficiency stress stimulated root growth. Compairing with P-inefficent genotypes, main root length and root/shoot ratio of P-efficent genotypes increased significantly under P deficiency stress, and photosynthetic rate and ability of resistance membrane lipid peroxidation of P-efficent genotypes were higher than that of P-inefficent genotypes. |
