Abstract:: Using Qinling wild Rhododendron calophytum as experiment material，the effect of different solution of ABT-6 and IBA and three matrixes on rooting rate in wild rhododendron calophytum of Qinling Rhododendron calophytum was studied.The results showed that,100 mg/L ABT-6 and 200 mg/L IBA induced greatest number of roots.The wild Rhododendron calophytum treated with grass carbon and commensurable vermiculite had the highest rate of rooting,the pure grass carbon was lowest inversely.And the growth process was also observed with the aboveground and unserground part,leaf apex was sprouted from the cutting slips in 15 days,and the leaf was matured in 30 days.In addition,callus in transverse section and roots with underground part was formed in 20 and 30 days,respectively.
