| 摘 要： | 研究了旱作对籼、粳亚种间产量及其相关性状的影响,并用逐步回归分析法建立亚种间水稻旱作的产量回归模型。研究表明,旱作在生育期、分蘖数、有效穗、穗长、株高、总粒数、结实率、千粒重等性状上对籼型品种的影响较粳型品种的影响大。在旱作条件下,粳型产量总体表现比籼型品种高。

| Abstract: | In this paper, the effect of dry cultivation on the agronomic traits and gain-yield of the Indica and Japonica rice(Oryza sativa L) were studied, and two functions about the grain-yield in dry cultivation of the Indica and Japonica rice were also derived with the stepwise regression analysis. The results indicated that the influence of dry cultivation in the agronomic traits, such as growth duration, tiller numbers, valid ear numbers, ear length, plant height, grain numbers, seed setting rates and 1000-grain weight, was displayed heavier in Indica than in Japonica. Under the condition of dry cultivation, the grain-yield of the Japonica was overall displayed higher than the Indica type. |
