管花肉苁蓉寄生实验体系的研究

Study on Experimental System of Cistanche tubulosa Parasitism

目的明确管花肉苁蓉寄生过程和环境条件，建立寄生实验体系。方法用塑料盒．沙土．玻璃板装置，培养柽柳和管花肉苁蓉，统计发芽率和接种率。结果黑暗、相对湿度100％，温度为20-30℃条件下，管花肉苁蓉接种率为63％；种子萌发后，接种上管花肉苁蓉的时间为7～12d。结论黑暗、相对湿度100％、温度为20～30℃是管花肉苁蓉寄生的适宜环境条件。

OBJECTIVE To clarify the process and environmental condition of Cistanche tubulosa parasism thus to estabalish a experimental system. METHODS The seeds and its host, Tamarix chinensis lour, were cultured in a new set-up made of plastic box. The germination percentage of seed and parasitism percentage of Cistanche tubulosa were examined. RESULTS Under dark condition with relative humidity of 100% and temperature between 20 -30 ℃, the Cistanche tubulosa parasite percentage was 63% and its parasitism duration was 7 - 12 d. CONCLUSION Cistanche tubulosa parasitism needs dark, relative humidity at 100% and temperature between 20 - 30 ℃.
