| 摘 要： | 以荞麦为试材,用五种剂量的铝进行土培,发现低浓度(0.435+0.6gAl3+/kg土)的铝能增加荞麦的总根长、根尖数和根系活力,减小根平均直径,降低根质膜透性,对荞麦生长有一定的促进作用;高浓度的铝(0.435+1.2gAl3+/kg土)会使荞麦的根变短、变粗、侧根减少,根系活力下降,根质膜透性升高,明显不利于荞麦的生长发育。

| Abstract: | Effect of aluminum on root growth of buckwheat was studied under different treatments of Al(aluminum)(0,0.3,0.6,0.9,1.2 g·kg -1 ). The results indicated that low Al(0.6 g·kg -1 )content in soil promotes root growth of buckwheat by increasing total root length,number of root tips,and root activity and decreasing membrane permeability of the root cells and average diameter of root. High Al(1.2 g·kg -1 )restrains growth of buckwheat by significantly inhibiting root elongation, thickening of root diameter,reducing root activity and greatly increasing membrane permeability of the root cells. |
