Abstract: The rapid propagation of tea clonal seedling was carried out in auto-controlled greenhouse. The result showed that when the technical route of tissue culture-direct rooting-greenhouse incubating was followed, the optimal initial explant was the third axillary bud of spring shoots, which possessed the best germination rate, proliferated 2.75 times in one incubation cycle, and 20% of the cultures could grow to more than 5βcm length every cycles. On the other hand, when the technical route of direct greenhouse cutting and incubation was followed, biannual proliferation could be achieved with one started in middle March and harvested after 5 months while the height of seedlings reached 20.4±8.3βcm, the transplant survival rate of these seedlings was close to 100% after they were proper conditioned. The other proliferation started at about Aug. to Sept., after about 6 month’s incubation, the height of those seedlings reached more than 20βcm after the rootage was established during winter. The increment of seedling height of those fertilized was 5.9 times as much as those unfertilized.
