| 摘 要： | 在田间条件下对6个糯稻品种的群体光合速率的动态变化及稻米品质进行了比较研究。结果表明，糯稻群体光合速率随生育期的变化基本上为单峰曲线，在齐穗期达最大值，但不同类型品种间有差异。齐穗期的群体光合速率与精米率和整精米率呈显著和极显著负相关，齐穗后26d的群体光合速率与精米率呈显著正相关。

| Abstract: | Canopy apparent photosynthetic rate(CAP) and grain quality of glutinous rice were studied in the field experiments.The results indicated that the changes of CAP is unimodal curve during growth stages,and were different with rice varieties,the maximum rate appears at heading stage.There were significant or highly negative correlation and significant positive correlation between the CAP of heading days and 26 days after heading and milled rice percentage of rice. |
