Abstract: Induction on direct rooting of tea tissue culture microshoots with different levels of phytohormone was expermented in greenhouse. We screened out the optimum levels of hormone, analyzed the dynamics of the percentage of rooted seedlings under different hormone levels, and established the technology of direct rooting of tea microshoots in greenhouse. The results showed that the surviving rate of seedlings was 66.7%, the rooting rate was 60%, about 90% of those survived seedlings, the average amounts of root was 9.4, and the length was 3.64βcm at the 70^th day after instantaneous dipping treatment of 100βmg/L IBA. This technology might be developed for commercial application of tea tissue culture procedure and the industrialized incubation of tea seedlings.
