哈密大枣以根蘖繁殖为主 ,繁殖系数低 ,不易保证母株优良品性的遗传稳定性。 1 994～ 1 998年 ,在引进、消化和吸收的基础上 ,利用组培技术 ,对哈密大枣优质苗木外植体的诱导 ,培养基的筛选 ,试管苗的继代扩繁和生根培养进行了探讨。试验得出 ,B9培养基是哈密大枣发芽 ,生根适宜培养基 ,且可一次成苗。B8培养基是哈密大枣继代扩繁 ,产生丛生芽的适宜培养基 ,月繁殖系数平均可达 3以上。 Hami jujube mainly reproductive root tillering, reproductive coefficient is low, not easy to ensure the genetic stability of maternal good character. From 1994 to 1998, on the basis of introduction, digestion and absorption, tissue culture techniques were used to induce explants of high quality seedlings of Hami jujube, selection of culture medium, propagation and in vitro rooting of test tube seedlings Exploring. Test results show that B9 medium is germinated Hami jujube, rooting suitable medium, and can be a seedling. B8 medium is Homily jujube propagation on the next generation, producing Cong Shou appropriate medium, the average monthly reproductive coefficient of up to 3 or more.
