| 摘 要： | 以引入的优质甜玉米品种亚当系列为研究对象,运用灰色关联度分析方法,分析青苞产量与主要农艺性状的关系。结果表明:主要农艺性状与青苞产量的关联度大小排序为行粒数>丝前日数>穗行数>穗粗>株高>穗位>穗长>百粒重。行粒数、丝前日数、穗行数是影响青苞产量最高的3个因素,百粒重对青苞产量的影响最小。该结果与前人进行的普通玉米的分析结果不完全一致,出现差异可能与品种、环境不同有关。

| Abstract: | Fresh corn yield and 8 agronomic characters of Adam series sweet corn were analyzed with grey relational analysis.The results showed the relational degree order of agronomic characters and fresh corn yield were as follows: kernel per row>germination-reap>row per ear>ear diameter>plant height>ear height>ear length>100-kernel weight.The kernel per row,germination-reap,row per ear were the main factor affecting fresh ear yield of sweet corn,and the 100-kernel weight was the minimal impact on fresh ear yield.The result is not completely consistent with the results of ordinary corn.The difference may be due to species,the environment and so on. |
