种植密度对高油玉米产量及产量构成因素的影响

Effect of Plant Density on the Yield and the Yield Components of High-oil Maize

采用灰色关联度分析法,对玉米产量及产量构成主要性状进行了分析评价。结果表明:高油115行粒数对产量影响最大,高油Xy-1株高对产量影响最大,而高油298和Sc704则是穗粗对产量影响最大。

The yield of high-oil maize and the main characters were analyzed by grey relational grade analysis method. The result indicated that the most contribution to the yield of Gaoyou 115, Gaoyou Xy-1, and Gaoyou 298 and Sc704 was row grains, plant height and ear diameter, respectively.
