利用正交试验方法研究了激素 6 BA、IAA、GA3和蔗糖 4个因子对扁桃 (AmygdaluscommunisL .)砧木试管苗丛生芽生长的影响 ,并筛选出扁桃砧木组织培养的优化培养基 .结果表明 :激素浓度 6 BA 1 5mg/L、IAA 0 2mg/L、GA 30mg/L和蔗糖 30mg/L为最优组合 ;从极差分析可知 ,4个因子的重要性依次为 :6 BA、GA3、蔗糖和IAA . The effects of hormones 6 BA, IAA, GA3 and sucrose on the growth of shoots in vitro of Amygdaluscommunis L. rootstock were studied by orthogonal test, and the optimized culture medium was screened for the tissue culture of Almond rootstock.The results showed that hormones The optimal combination of 6 BA 1 5 mg / L, IAA 0 2 mg / L, GA 30 mg / L and sucrose 30 mg / L was the best. The significance of the four factors was 6 BA, GA3, sucrose and IAA.
