摘要
The effect of thidiazuron (TDZ) on the micropropagation of Camellia sinensis (China hybrid) was compared with that of benzylaminopurine (BAP) using nodal segments from in vitro raised seedlings. Extremely low concentrations of TDZ (1pM-100nM) alone were effective in inducing shoot bud proliferation and maintaining high rates of shoot multiplication on hormone-free media. On the other hand, higher concentrations of BAP (1-10 mu M) and its continued presence were required to initiate and sustain shoot proliferation. While wider ranges of BAP combined favourably with auxins like NAA or IBA, only specific combinations of TDZ and NAA were effective for shoot proliferation. TDZ treated explants yielded healthy shoots, with sturdy leaves, even during the initial stages of growth, whereas, the effect of BAP was cumulative over subcultures in attaining a high proliferative rate.
