| 摘 要： | 为探索谷子孕穗期在干旱环境的光合适应机制，筛选谷子孕穗期抗旱性光合参数鉴定指标，以20个谷子品种为试验材料，在模拟干旱棚中研究了谷子孕穗期干旱胁迫条件下光合参数指标的的变化。结果表明：干旱胁迫处理的相对叶绿素含量和相对光合速率与品种的抗旱指数呈极显著正相关，且灰色关联度较高，可作为评价谷子孕穗期抗旱性的光合参数指标。

| Abstract: | Foxtail millet may suffer from serious drought stress during their growth period,which affects their photosynthesis activities.Previous studies identified that booting stage before heading is the most sensitive period to water shortage in the development of foxtail millet.In this trial,20 foxtail millet cultivars' photosynthetic characteristics correlated with drought resistance index(DRI) were monitored under both normal and drought stress conditions during booting stage.Results showed that relative chloro... |
