摘　　要：在铝质量浓度为120 mg.L-1下,对9个不同品系圆叶决明牧草进行培养。通过农艺性状、主根伸长率、根系电导率、根系活力和脯氨酸含量变化测定,研究不同圆叶决明品系的耐铝性。结果表明,86134R2、86134R3、86134R1决明品系属于耐铝的圆叶决明牧草品系;34721R2、34721F7、92985R2、34721R1、34721F4、92985R1属于铝敏感圆叶决明牧草品系。Ten strains of Chamaecrista were cultivated in soil with 120 mg · L^-1 of Al^3＋. Al^3＋ tolerance of these strains was studied measuring the agronomic characteristics, elongation rates of main root, root conductivity, root activities and proline content. The results demonstrated that the strain 86134R2, 86134R3, 2204 and 86134R1 had high tolerances to Al^3＋; the strain 34721R2, 34721F7 and 92985R2 had medium tolerances; and, the strain 34721R1, 34721F4 and 92985R1 had low Al^3＋ tolerances.
