不同栽培条件下糯玉米鲜产量及构成因素的通径分析
Path Analysis about Waxy Corn Yield and Its Components under Different Cultivation Conditions
摘要
Abstract
Luyunuo No.9 was used as material in this ‘3414’ experiment with treatments of two planting modes (direct broadcasting and transplantation) and three densities (45 000,52 500 and 60 000 strain/hm2).Path analysis was made between six ear characters (ear length,ear diameter,barren ear tip,ear row number,kernels per row,1000-kernel weight) and fresh ear yield.The results showed that ear diameter had extremely important effect on direct contribution to fresh ear yield under different planting pattems and densities.The ear length had better direct contribution to fresh bud yield and fresh ear yield at low and medium density.Ear row number had larger direct contribution to fresh bud yield and fresh ear yield at high density.关键词
