| 摘 要： | 对垂枝桦芽茎段组织培养技术的外植体启动培养、丛生芽增殖以及试管苗生根等方面开展研究。结果表明:在1/2MS+6-BA1.00 mg.L-1+NAA0.05 mg.L-1+蔗糖30 g.L-1的培养基上,外植体诱导率最高;在1/2MS+6-BA0.20 mg.L-1+NAA1.50 mg.L-1+蔗糖30 g.L-1的培养基上,外植体增殖系数最高,可达5～8倍;在1/2MS+NAA0.50 mg.L-1+蔗糖20 g.L-1的培养基中,继代苗的生根率可达100.0%。

| Abstract: | This article studied the tissue culture of Betula pendula,including inducing callus,buds multiplication and radication of tube seedlings in different culture mediums.The result showed that the highest inducement occurred in culture medium with 1/2MS＋6-BA1.00 mg·L-1＋NAA0.05 mg· L-1＋30 g·L-1saccharose;the highest bud multiplication occurred in culture medium with 1/2MS＋6-BA0.20mg·L-1＋NAA1.50 mg·L-1＋30g·L-1 saccharose,at where the multiplication coefficent was up to 5～8;the highest rooting rate occurred in culture medium with 1/2MS＋NAA0.50 mg·L-1＋20 g·L-1saccharose culture medium,and the rooting ratio could reach to 100.0%. |
