Abstract: The net photosynthetic rate of flag leaf was measured at the filling stage and maturity stage of ratooning rice with thirteen hybrid rice combinations as materials. The net photosynthetic rate at the filling stage of ratooning rice was significantly higher than that at the maturity stage, and the difference in the photosynthetic rate at the filling stage was more than that at the maturity stage among all the combinations, and the net photosynthetic rate was significantly different at the same stage among different combinations. The net photoynthetic rate at the filling stage was positively correlated with the yield of ratooning rice, and that at the maturity stage was significantly and negatively correlated with the yield of ratooning rice. In addition, the net photosynthetic rate at the filling stage was significantly and positively correlated with the seed setting rate.

摘要: 以13个杂交稻组合为材料,分析了再生季产量及其构成因素与水稻灌浆期和成熟期光合速率的相关性。结果表明, 再生稻灌浆期净光合速率显著高于成熟期,且灌浆期不同组合间的差异大于成熟期。不同组合间在同一生育期净光合速率存在显著差异。再生稻灌浆期的净光合速率与产量呈极显著正相关,而成熟期净光合速率与产量则呈显著负相关。此外,灌浆期净光合速率与结实率呈显著正相关。
