小麦茎秆与单穗重的相关性分析

Correlation Analysis of Wheat Stem and Single Spike Weight

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.

In this paper, we study correlation analysis between wheat stem and single spike weight. We measure stem length ender ear, stem diameter, ear length, plant height, section thickness and section weight of 6 wheat cultivars. According to the data, correlations between stem traits and single spike weight were analysised. The results show that the association between wheat stem and single spike weight was to a varying extent. Namely, stem diameter, section thickness, section weight are in negative correlation respectively. The relationship between plant, stem length and single spike weight is not obvious and complicated. We should discuss in different cases.
