| Abstract: |
| A newly-selected superior family of Schima superba Gardn.et Champ was used for tissue culture and micropropagation. The explants of stem segments displayed the optimum initial growth on the primary media GD 6-BA 1.50 mg?L-1 NAA 0.50 mg?L-1, the highest proliferation rate of 3.1 times on subculture GD 6-BA 1.00 mg?L-1 IAA 0.30 mg?L-1, and 96.67% rooting rate on medium 1/2GD IBA 1.00mg?L-1 NAA 0.05mg?L-1 IAA0.80mg?L-1 Suitable techniques and procedures were identified for acclimatization, transplantation and later-period management of tissue-cultured plantlets. The survival rate of the superior family was 92.2%. |
