| 摘 要： | 通过田间试验分析12个广东省区试花生品种根系特征与地上部分性状的相关性.结果表明:根质量在各生育期均与地上部质量、总质量呈显著或极显著正相关关系:开花期根系活力与地上部分多数性状呈极显著正相关关系,不同时期的根系活力均与成熟期产量呈显著正相关关系;成熟期根冠比与产量呈显著负相关关系.说明花生根系特征与地上部分性状关系密切,花生生长后期保持根系活力对产量的形成具有重要作用.

| Abstract: | Twelve peanut varieties were selected to analyze the correlation between root and aboveground traits. The results showed that root mass had positive correlation with shoot mass and total mass at three growth stages. The activities of the roots at different growth stage had significant correlation with the yield at the mature stage. However, the root/shoot ratio had negative significant correlation with yield at the mature stage. The result suggested that the root system was closely related with the abovegro... |
