摘要
将柽柳幼嫩枝条接种于诱导培养基上诱导出丛生芽,再把柽柳丛生芽和嫩枝接种在含有不同浓度NAA的MS培养基上,使外植体分化生根。结果表明:添加0.05 mg/L NAA的MS培养基适宜丛生芽生根;添加0.01 mg/L NAA的MS培养基适宜柽柳嫩枝生根。两种试管苗长势不同,其中由柽柳嫩枝产生的试管苗,移栽成活率较高。
Young branches of Tamarix chinensis were inoculated in MS medium for cluster bud, then these buds and young branches were transferred to MS medium supplemented by different concentration of NAA for root induction. The result showed that： MS ＋ NAA0.05 mg · L^- 1 was the ideal induction rooting medium for cluster bud while MS ＋ NAA0.01 mg · L^-1 for young branches. The two kinds seedlings had different growth, and the seedlings directily from young branches had the higher transplantation survival ratio.
