不同培养条件及方法对组培暗紫贝母生长的影响

Effect of Different Cultural Conditions and Methods on the Growth of Cultured Bulb of Fritillaria unibracteata Hsiao et.K.C.Hsia

暗紫贝母(Fritillaria unibracteata Hisao et K.C.Hsia)是百合科植物,其鳞茎为川贝来源之一,具有清热润肺、化痰止咳、散结等功效。但由于它喜寒凉气候,为高山、高原特有植物,只能野生生长在3000～3500 m的高山上,栽培很难成活。为了弥补野生资源的不足,探讨药材生产新途径。

The paper reports the growth rates and alkaloid contents of Fritillaria unibracteata Hsiao et. K. C. Hsia in tissue culture by 3 temperatures, 2 lightings and 3 cultural methods experiments. The results show that the highest growth rate and alkaloid content of cultured bulb is in shake culture at 20℃. There is no significant difference between light and dark culture.
