培养基中蔗糖浓度及添加氨基酸对组培暗紫贝母生长的影响

The Effects of Concentration of Sucrose and Addition of Aminos on the Growth of Cultured Bulb of Fritillaria unibracteata

研究了培养基中不同蔗糖浓度和添加Ｌ－酪氨酸或Ｌ－赖氨酸对组培暗紫贝母鳞茎的生长率和生物碱含量等的影响。结果表明：蔗糖浓度为５％时，鳞茎的生长率和生物碱含量最高，培养基中添加氨基酸可以提高鳞茎的生长率。

The paper reports growth rate and alkaloid content of Fritillaria unibracteata in tissue culture by different sucrose concentrations and 2 aminos additional experiments.The results show that the highest growth rate and yield of alkaloid is in 5%sucrose concentration.The addition of aminos is favorable to the growth of bulb, but not to the accumulation of alkaloid.
