| Tóm tắt: | Leaves and young petiole of Begonia bataiensis were sterilized with 10% calcium hypochlorite (Ca(OCl)2) and indurations of 0, 4, 6, 8, 10, and 12 minutes. Then they were plated on media consisting of a half dish of MS supplemented by 30 g/l sucrose and 7.5 g/l agar. After 21 days, the culturing rate of clean samples was 81.7%. Leaves and stems of the transplanted plants in vitro were cultured on a half dish of MS media supplemented with 30g/l sucrose, 7.5g/l agar and plant growth-regulators: 2.4-Dichlorophenoxyacetic acid (2.4D) and thidiazuron (TDZ). Various concentration of TDZ (0; 0.1; 0.3; 0.5; 1 mg/l) were used. After 21 days, results were obtained for 96% of the callus on the medium supplemented with 0.3 mg/l TDZ. The callus had a fresh weight of 2,642 mg/sample and a dry weight of 271 mg/sample. The calluses were transferred onto a medium for forming shoots and roots to complete the plant in vitro. |
