不同品种小麦耐低钾特性研究

Study on the variance of tolerance to low-K stress among different wheat cultivars

利用盆栽试验,连续两年对33个小麦品种进行全生育期培养,研究两种供肥水平下不同品种小麦相对经济产量、相对钾素积累量和相对钾素利用效率相关性,结果发现,研究不同品种小麦的钾效率遗传机理时,相对钾素利用效率指标要优于相对经济产量、相对钾素积累量指标。

From 2004 to 2005, adopting pot trial under the two conditions of high potassium and low potassium levels, we studied the variance of tolerance to low - K stress among 33 wheat cultivars, comparing the same index＇s analysis results of the two years showed that the relative potassium utilizing efficiency was better than relative economic yield and relative potassium accumulated quantity were all remarkably correlated.
