Preliminary Study on Tissue Culture and Fast Propagation Technology of Catalpa bungei
摘要
Abstract
[Objective] The aim was to achieve rapid propagation of Catalpa bungei and provide a theoretical basis for large-scale seedling production. [Method] Axillary bud of Catalpa bungei were used as explants, while different medium and hormone combinations were selected to set up the tissue culture and rapid propagation system of Catalpa bungei . [Result] N_6+2.0 mg/L 6-BA +0.005 mg/L NAA is an appropriate culture medium for germination of axillary bud, MS+1.5 mg/L 6-BA +2.0 mg/L NAA is the best medium for callus induction, MS+0.5 mg/L 6-BA +0.5 mg/L NAA is suitable for bud differentiatation and N_6+1.5 mg/L 6-BA +0.005 mg/L NAA for subculture multiplication. 1/2 MS+0.5 mg/L NAA was of advantage to rooting culture. [Conclusion] The propagation speed of Catalpa bungei was greatly improved by tissue culture method.关键词
