【摘要】 对红叶石楠芽的增殖和根的分化进行了研究,实验结果表明：红叶石楠芽增殖的最佳培养基为MS+2．0mg/L BA+0．5mg/L KT+0．2mg/L IBA,最佳增殖区段为基部,根的分化以NAA预处理2h和3%蔗糖浓度为佳．更多还原

【Abstract】 Phtinia fraseri“Red Robin”is a tree which comes from overseas.In this paper,the methed is set up through researc- hing the effects of different culture mediums on Phtinia fraseri“Red Robin”in vitro.The results show that the proliferation effi- ciency of shoots in MS medium additioned 2.0 mg/L BA+0.5mg/L KT+0.2MG/L IBA is best.The bottom of segment is much better than the top segmen,it grows healthy through green leaves.Having 2 hours NAA pretreatment make the plant grow best and its rooting efficiency is 70%.The plant longs up to 2.85cm and grows healthy.And the best sucrose concentration is 3%.更多还原
