摘要
以金乡大蒜鳞茎为外植体,研究了不同贮藏时间对大蒜无性繁殖体系的影响。结果表明:大蒜组织培养扩繁的最佳时期为收获后61～122 d(即休眠解除后幼芽萌动期)。在此期间大蒜组织培养各指标(外植体出愈率、出愈量、胚性愈伤组织诱导率,分生不定芽的直径、发芽率、平均发芽数,分生不定根的生根率、平均生根数)均达到较高水平。
The effect of different storage times on garlic(Allium sativum L.)asexual propagation system was studied in this experiment.The results indicated that the best time for garlic tissue culture reproduction was 61-122 d after harvest(i.e.garlic shoots break bud dormancy period).During this period,various indicators of garlic tissue culture including callus volumerate,rate of embryogenic callus,meristematic bud diameter,germination rate,average germination number,meristematic adventitious rooting rate,the average root number,etc.all reached higher levels.
