摘要
对 30个马占相思优树无性系进行组培增殖、生根技术研究 ,观察 1 2a月增殖率、生根率指标 ,揭示不同无性系早期增殖速率的差异 ,研究表明 30个无性系可分为快、中、慢 3种增殖类型 ,快增殖类型无性系经过 9代 (13 15个月 )培养达到较高增殖率 (2 18倍·月- 1) ,具备较好的生根性能(91 0 % ) ,中、慢增殖类型无性系需 12 15代 (18 2 2个月 )培养才达到较高增殖率。
The technique of multiplicative and rooting ratio in vitro of 30 plus tree of Acacia mangium was studied. There are great difference among clones in multiplication and rooting at the early stage of tissue culture. The results show that 30 clones can be divided into 3 multiplicative types, i.e. fast, middle and slow multiplicative types. The fast one can reach to high monthly multiplicative ratio (2.18 times per month) after 13 to 15 months'introduction while it has good rooting property with 91.0 per cent. But the middle and slow one can't get the high monthly multiplicative ratio till they got 18 to 22 months' introduction.
