图8 不同抗旱类型玉米品种产量与其影响因素的相关性分析 YD：产量；Pre-DM：花前干物质积累量；Post-DM：花后干物质积累量；Total-DM：成熟期干物质积累量；Post-LAD：花后LAD。“**”表示在P < 0.01水平显著相关，“ns”表示无显著相关性。

Fig.8 Correlation analysis between yield and its influencing factors in maize cultivars with different drought-tolerant types YD: yield; Pre-DM: pre-flowering dry matter accumulation; Post-DM: post-flowering dry matter accumulation; Total-DM: total dry matter accumulation at maturity; Post-LAD: post-flowering LAD.“**”indicates significant correlation at the P < 0.01 level,“ns”indicates no significant correlation.
