| Abstract: | In order to select the best technique for rooting of the girdled tea branches,the effects of maturation degree,exogenous hormones concentration,stem diameter and girdling mode on development of root primordium were studied in this paper.The results showed that the healthy and strong branches should be chosen with 0.25~0.28 cm of stem diameter,and then be girdled on the yellow-green or blue-green stem segments and covered with 100 mg/L ABT-1 rooting powder.After 40~50 days,when the bandaged stem showed epidermis uplifts or white root points,the branch could be cut from the parent tree and planted in the substrate for root culture. |
