| 摘 要： | 采用盆栽方法研究了分蘖期水分胁迫对水稻生长发育及产量的影响。结果表明：分蘖期水分胁迫对水稻分蘖数、叶面积指数(LAI)和株高都有较大的影响，影响的严重程度与水分胁迫水平相一致。处理组水稻平均分蘖数、LAI、株高分别比对照低28％、26．6％、14．4％。由于分蘖期水分胁迫抑制了水稻的生长发育，影响了水稻分蘖的发生与生长，最终导致单位面积的有效穗不足、穗粒数低而严重影响产量，处理组平均产量比对照低29．5％。

| Abstract: | The effects of water stress on growth and yield of rice were studied in tillering stage with the method of pot cultivating. The results showed that the effects of water stress on tillering number, LAI, and plant height of rice were evident and the seriousness of effects is consistent with the levels of water stress. The average tillering number of the treated was 28% lower than that of the control,the average LAI of the treated was 26.6% lower than that of the control,and the average height of plants of the treated was 14.4% lower than that of the control. Because of water stress on rice in tillering stage, rice tillering was restrained, yield was seriously affected with no enough effective ears and the grains of ear in unit area, and the average yield of the treated was 29.5% lower than that of the control. |
