Research progress in alfalfa allelopathy

Abstract

Abstract: Medicago sativa is a perennial legume with high nutrition and multiple ecological functions,cultivated comprehensively all over the world.Generally,M.sativa has a productivity peak at the 2nd～4th plant year,and it is difficult to reestablish M.sativa in the same field after a short interval.M.sativa plant contains water-soluble substances that are toxic to itself (autotoxicity) and to other plants (allelopathy).The research progress in M.sativa allelopathy was reviewed in this paper,including the main allelochemicals of M.sativa,factors influencing M.sativa allelopathy,and the applied research on M.sativa allelopathy.Moreover,the future research directions of M.sativa allelopathy were put forward.

Key words: Rare earth element, Plant, Biological effect, Mechanism
