本文应用灰色关联度分析法 ,对宁夏 1 0个春小麦品种 (系 )的灌浆速率、光合速率与气象要素之间的关系进行了分析。结果表明 :灌浆速率与气象要素的关联度排序为 :辐照>平均温度 >相对湿度 ;光合速率与气象要素的关联度排序为 :平均温度 >相对湿度 >辐照。对高产育种及高产栽培有一定参考价值
In this paper, the relationship between the filling rate, photosynthetic rate and meteorological factors of 10 spring wheat cultivars (lines) in Ningxia was analyzed by gray relational analysis. The results showed that the order of correlation between grain filling rate and meteorological factors was as follows: radiation> average temperature> relative humidity; the correlation of photosynthetic rate and meteorological elements was ranked as: average temperature> relative humidity> irradiation. It has some reference value for high-yield breeding and high-yielding cultivation
