| 摘 要： | 以对SMV3抗性不同的四个大豆品种(系)为材料，分析其感染SMV后各生育阶段的总多酚和总黄酮的含量及变化。结果表明：抗感病品种未接种健株中总黄酮、总多酚含量，抗病品种明显高于感病品种，接种SMV3后总黄酮、总多酚含量抗病品种变化不大，感病品种两指标含量明显提高，二者动态变化也明显不同。抗感病品种类黄酮配基组成相同，接种SMV3后，感病品种增加了P3配基，部分缺少了P4配基。大豆中总黄酮、总多酚的动态变化及黄酮配基的组成与增减均可作为鉴定抗感病品种的生化指标。

| Abstract: | The contents of total polyphenol and total flavonoids(CPF) were determined in 4 cultivars (2 resistant, 2 susceptible) inoculated with SMV 3 at different stages. The results indicated that (1) CPF in resistant cultivars were higher than CPF in susceptible cultivars when they were not inoculated with SMV 3; (2) CPF in resistant cultivars inoculated with SMV 3 varied a little as compared with those not inoculated with SMV 3, CPF in susceptible cultivars inoculated with SMV 3 increased as compared with those not inoculated with SMV 3, and changes of CPF displayed different curves between resistant cultivars and susceptible cultivars; (3) the composition of flavonoids in resistant cultivars were same as that in susceptible cultivars. P 3 of flavonoids increased and P 4 of flavornoids decreased when susceptible cultivars were inoculated with SMV 3. Therefore, the changes of CPF and composition of flavonoids can be considered as a physiochemical target to determine resistance of cultivars. |
