影响超甜玉米子粒种皮厚度因子的关联分析

应用灰色关联分析法,对近年参加广东省超甜玉米区域试验的8个超甜玉米组合乳熟期鲜穗子粒种皮厚度与其他主要农艺性状间的相关性进行了分析.结果表明;子粒种皮厚度与其他10个农艺性状间的关联度排序为穗行数＞行粒数＞株高＞单苞鲜重＞穗粗＞穗位高度＞穗长＞单穗鲜粒重＞单穗净重＞可溶性多糖含量.这说明穗行数对子粒种皮厚度影响最大;行粒数和株高以及单苞鲜重对子粒种皮厚度影响次之;而可溶性多糖含量对子粒种皮厚度影响最小。

Grey Correlative Degree Analysis of the Factors Influencing the Grain Pericarp Thickness of Super Sweet Corn Hybrid

The correlation of main agronomic traits and their effect on grain pericarp thickness was studied by using the grey correlative degree analysis.The results showed that the order of correlative degree between pericarp thickness and other agronomic traits was row number per ear> kernel number per row > plant height > fresh ear with leaves weight per ear > ear diameter > ear height > ear length > fresh grain weight per ear >net grain weight per ear > water-soluble polysaccharose (WSP).Which also showed kernel number per row was closely related to row number per ear;next to them are kernel number per row,plant height,net weight per ear,ear diameter,ear height,ear length,fresh grain weight per ear,fresh ear with leaves weight per ear; water-soluble polysaccharose(WSP) was less related to grain pericarp thickness.
