Abstract

Abstract: Alfalfa(Medicago sativa L.) plants of different aged stands were collected from Qingyang and Dingxi,Gansu Province on the Loess Plateau.The effects of aqueous extracts from different plant parts on alfalfa seed germination were investigated using filter paper method.The results showed that the aqueous extracts from alfalfa plant had inhibitive effects on seed germination and seedling growth,and extract from alfalfa flowers had the strongest inhibitory effect.Aqueous extract from Qingyang 4-6 year stand had the strongest inhibitory effect to hypocotyl length in comparison with the aqueous extract from Qingyang 10 year stand.Radical length was relatively more sensitive than hypocotyl length to autotoxic alleochemicals.Hypocotyl and radical elongation of alfalfa were inhibited more by alfalfa extracted solution than the germination.For 4-6 year stand alfalfa,rotation should be adopted to overcome the autotoxicity effects.

Key words: Alfalfa, Aqueous extracts, Autotoxicity, Seed germination, Seedling Growth

摘要： 以甘肃庆阳、定西异龄陇东苜蓿(Medicago sativa L.cv.Longdong)植株为材料,用纸上发芽法,研究不同生长部位水浸液对其种子萌发的影响。结果表明:植株各部位水浸液对其种子萌发存在自毒作用,其中以花的水浸液抑制作用最强;庆阳4—6龄苜蓿水浸液的自毒作用最强,10龄后则有所减弱;在干旱条件下苜蓿胚根比胚芽对其水浸物更敏感,水浸液对其胚芽、胚根的抑制效应强于发芽率,建议4-6龄苜蓿应通过轮作克服其自毒作用。
