Effects of lucerne plants on germination of lucerne

摘要：

Auto‐toxicity, an intraspecific form of allelopathy,occurs when chemical substances from plant material inhibits or delays germination and growth of the same species.Lucerne ( medicago sativ a), a perennial legume, contains water — soluble substances that are toxic( Chung and Miller, 1995 ).Given the likelihood of allelopathy effects when interplanting, double cropping, no‐till planting and nonrotational cropping, we looked for evidence of allelopathy in lucerne as may be important when reestablishing lucerne in a former lucerne field.
