主要是分析茎秆与单穗重和产量的相关性.以6个小麦品种为材料,分别测取了穗下茎长,茎粗,穗长,株高,节壁厚,节重及单穗重,对茎质与穗重进行了相关分析,结果表明:茎秆性状与穗重存在不同程度的相关性.其中,茎粗与单穗重呈正相关;节壁厚与单穗重呈正相关;节壁重与单穗重呈正相关;而株高和茎长与单穗重的关系不明显且较为复杂,应分情况讨论.
Mainly to analyze the correlation between stems and single ear weight and yield.With 6 wheat varieties as materials, the stem length, stem diameter, ear length, plant height, wall thickness, weight and single ear The results showed that the correlation between stem traits and ear weight was significant, in which stem diameter was positively correlated with single panicle weight, and the wall thickness was positively correlated with single ear weight. Section wall weight and single ear weight were positively correlated; and the relationship between plant height and stem length and single ear weight was not obvious and more complicated, should be divided into different situations.
