| 摘 要： | 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.

| Abstract: | 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. |
