| 摘要: |
| 利用小容器溶液培养法对耐铝性鉴定条件和52份普通荞麦栽培品种资源的耐铝性进行了研究。结果发现普通荞麦耐铝性鉴定的适宜条件为发芽种子于500 μmol/L AlCl3溶液(pH4.5)处理3 d,以发芽种子在这三天内的根伸长量衡量耐铝性程度。在该处理条件下,普通荞麦不同品种间的耐铝性有显著差异。其中,陕西大红花甜荞品种、日本大粒荞、织金红花甜荞的耐铝毒胁迫能力最强,值得在荞麦耐铝性育种和耐铝机制研究中利用。 |

| Abstract: |
| The estimating system of common buckwheat Al3+ tolerance and the Al3+ tolerance of 52 common buckwheat accessions were studied by means of test tube culture method. The results showed that the effective method of the Al3+-tolerance identification for common buckwheat are to treat sprouting seeds three days in the 500 μmol/L AlCl3 solution(pH4.5)at 25 ℃ and to use the seed root growth length in the three days for evaluating the degree of Al3+ tolerance. The results of identification of Al3+-resistance by this way showed that there are great variations of Al3+ tolerance among the different common buckwheat accessions. Among them,some accessions such as Dahonghua from Shaanxi,Daliqiao from Japan,and Honghuaqiao from Guizhou have much higher Al3+ tolerance than others,which can be used for studies on the buckwheat breeding and the mechanism of the buckwheat Al3+ tolerance. |
