与非受旱的生长条件相比,对受旱条件下小麦的产量与产量构成因素之间的关系。至今没有比较一致的意见。为此,作者测定了抗旱性不同的23个春小麦的干物质积累与损失模式,并将这些特性与抗旱性和产量联系起来进行分析。试验在大田栽培条件下共进行了五年,现将结果介绍于下:
The relationship between wheat yield and yield components under drought conditions was compared with that under non-drought conditions. So far there is no more consensus. To do this, the authors determined the patterns of dry matter accumulation and loss in 23 spring wheat varieties with different drought resistances, and analyzed them in relation to drought resistance and yield. The experiment was carried out for five years under field cultivation conditions and the results are presented below:
