| 摘 要： | 研究三点金Desmodium triflorum的耐铝能力对开发优秀的草坪地被植物有一定的重要性,研究表明,2种三点金草对Al3 有一定的耐受性,低铝浓度(20 mg/kg)对三点金草幼苗和成苗生长都有一定促进作用,但较高铝浓度(40 mg/kg)均会阻碍两者根系生长,使其侧根、根干质量和根冠比都有明显减少.在幼苗期,大叶三点金根系对Al3 有较高程度的耐性,但当两者再生长30 d后,小叶三点金对铝盐的耐受能力增强,相反大叶三点金则有所下降. |
| 关 键 词： | 小叶三点金 大叶三点金 铝盐毒害 |

| Abstract: | It was i mportant for producing good turf to study the tolerance ability to aluminumion ofD.microphylumandD.triflorum.We concluded that the ability of tolerance to Al3 +was ordered asD.triflorum>D.microphylum,and the growth ofD.triflorumandD.microphylumboth could bei mproved by low concentration of aluminum;superfluous aluminumion baffled the growth of theirroot systems,there was a significant decrease in their root biomass and root to shoot ratios. |
| Keywords: | D.microphylum D.triflorum Al3 +tolerance |
