Especially,in the medium of 1/2MS ＋ NAA 0.1 mg/L, the regrown shoots without roots of＂ Baltimore oriole ＂induction rate and the number of the roots both are the best, roots induction rate reached to 100% in 17 days.

红运&在0.1mg／L NAA的培养基上，生根数量和生根率都最好，17天生根率达到了100％；而&奶油卷在0.05mg／LNAA的培养基上，21天生根率达到100％。

The root inducation rate is 100% on the cotton, pearl rock and agar medium, but the number of root induced is maximum. The average number is 5.47. The young root possess many multistage branchs. The transplant effect also showed pearl rock is ideal substitute for agar.

The results showed that there was most distinct difference in rooting rate among seedling varieties, rooting substrates, among them, substrate mixed with cultivate soil and peat soil in proportion of 7-3 was the best one , 500mg/l NAA and IBA solutions had no distinct effect on enhance rooting, covered with plastic membrane had most distinct excelled to which covered none.

The twig production of different clones is different, from 5.5 twigs per month to 14.8 twigs per month. The rooting rate, root number and root length change regularly as the concentration of IBA goes up from 0.05 to 2.00 mg/L. At the concentration of 0.05 mg/L ppm IBA, rooting rate and root length are the highest. Cutting substrate also has eminent effect on rooting rate and survival rate, 50% peat plus 50% sub-top soil is the best substrate. The survival rate differs greatly among clones, from 56.7% to 90.0%. Rooting rate and survival rate change regularly as season changes. The rooting rate of May and June is middle, that of July and August is high and that of September and October drops rapidly. The survival rate is low in May, September and October and high in June, July and August.
