耐低钾小麦品种筛选及其吸钾特性的研究

SCREENING OF WHEAT VARIETIES WITH LOW POTASSIUM ENDURANCE AND STUDY ON THEIR POTASSIUM UPTAKE CHARACTERISTICS

  • 摘要: 1993~1995年在缺钾土壤上进行田间微区和小区试验,筛选耐低钾小麦品种并研究其吸钾特性。试验结果表明,在缺钾土壤上不同小麦品种的产量存在显著差异。以耐低钾力和品种适应性及分级指标进行评定,在微区试验的45份供试小麦品种中耐低钾能力强(1级)的占4.4%,耐性很差(7~9级)的占37.8%,其余介于二者之间(3~5级)的占与57.8%。川麦23和898耐性强的特点在小区试验中得到进一步验证。它们在缺钾条件下比敏感品种能够吸收较多的钾素,且有较多钾在成熟期转移到子粒中,因而在不施钾肥的条件下可获较高产量。

     

    Abstract: Field experiments were conducted to screen wheat varieties with low potassium (K) endurance from 1993 to 1995. The characteristics of K uptake among these varieties was also studied. The results showed that the yields of defferent wheat varieties were significantly different in K deficient soil. According to low K endurance, variety adaptability and the tractional method made by Liu Hengguan, 45 wheat varieties were identified by field experiment. Among 45 varieties tested, 4. 4% belonged to that of high endurance of low K (1 grade) and 37.8% to that of low endurance (7~9 grades) and the others (57. 8%) were between the former two types (3-5 grades). Further, the endurance of Chuanmai-23 and 89-8 were proved in plot experiment. The two varieties are able to absorb more K from soil and transfer more to grain in their maturity than sensitive ones. Therefore, Chuanmai-23 and 89-8 could yield well respectively under K stress.
