Abstract:
Chosen semi-woody stems of Rhododendron scabrifolium Franch.as the test material，handling cuttings with KIBA,KNAA and Hormodin,the soluble sugar and total nitrogen concentrations during rooting were determined.The results showed that quick dipped into liquid KIBA 3 000 mg/L had significant impact on rooting for cuttings,which obtained a higher rooting rate of 92.55%,and reached a significant level；Higher ratio of C/N was conducive to rooting cuttings,soluble sugar and nitrogen were critical nutrients for adventitious root formation and growth.During callus formation and root initiation，soluble sugar and nitrogen were high；High concentrations of nitrogen was not conducive to rooting cuttings.
