摘　　要：以平贝母休眠鳞茎为外植体,以MS为基本培养基,在添加IBA、6-BA、2,4-D、KT4种外源激素的2种培养基上,比较了GA不同浓度、不同处理时间对诱导平贝母不定芽以及不同浓度GA处理相同时间对诱导平贝愈伤的影响。结果表明:GA 500mg/L处理60h对打破平贝母鳞茎休眠效果最好,出芽率最高达45%,愈伤组织诱导率达33.3%。Using dormant bulbus of Fritillaria ussuriensis Maxim as explant,MS with different growth regulator as busic medium,the effect of different concentration and different time of GA on inducing indefinite bud and different concentration deal with the same time of GA on inducing callus of Fritillaria ussuriensis Maxim were studied.The results showed that use GA dealing with 60hwas the best for removing dormancy of Fritillaria ussuriensis Maxim’s bulbus.The bud ratio reached to 50%and the callus ratio reached to 33.3%.
