对30个饲用玉米品种17个植株数量性状品种间变量,品种内4 000株/667m2和4 500株/667m2两个种植密度处理间植株数量性状变量,进行二级系统方差分析,研究结果表明:17个性状的除穗位叶面积品种间变量达显著水平外,其余16个性状的品种间变量均达极显著水平;品种内密度处理间变量对株高、穗位高、穗位叶面积、节间数、穗位下节间数、叶干重、茎干重7个数量性状接受无效假设Ho,对基茎粗、枯叶数、叶鲜重、茎鲜重、穗鲜重、穗位下茎重、基茎重、穗干重、株鲜重、株干重10个数量性状则否定无效假设Ho,接受备责假设HA。
The results of two-way ANOVA showed that there was no significant difference between the quantitative traits of 17 quantitative traits in 30 maize varieties and 4 000 / 667m2 and 4 500 / 667m2 plant density traits in two cultivars The results showed that among the 17 traits, the inter-variety differences of ear-leaf area and leaf area reached significant level among the 16 traits. The inter- , Internode number, internode number under ear position, leaf dry weight, and stem weight were all null and void hypothesis Ho, which had no significant effect on stem diameter, dry leaf number, fresh weight of leaf, fresh weight of stem, fresh weight of ear, The stem weight, basal stem weight, dry weight of ears, fresh weight of plant, dry weight of 10 plants were negatively null hypothesis Ho, accept the hypothesis HA.
