Abstract

Abstract

The effects of NAA, IBA, 6-BA and TDZ on adventitious root induction and seedling strength of Pseudosasa japonica f. Akebonosuji were studied by using tissue culture seedlings as experimental materials. The results showed that NAA played a leading role in adventitious root induction, and the effect was better than that of IBA alone, much better than that of the combination of NAA, IBA and 6-BA. When the concentration of NAA was 0.5-2.0 mg·L^-1, the rooting rate reached 100% in 50 days. Under the concentration of 0.5 mg·L^-1, the rooting rate was 80% in 15 days and 100% in 30 days. The average rooting number was 6.95 and the average root length was 0.995cm. When NAA concentration was 0.2-0.5 mg·L^-1, the seedling effect was good, the multiplication coefficient was up to 8.5, and the average new bud length amounted to 1.595cm.The addition of activated carbon, 6-BA or TDZ could inhibit rooting and proliferation.
