Study on Feasibility Inoculating Cistanche tubulosa to Wild Tamarix chinensis in Yellow River Delta
Abstract:Objective:To analyze the feasibility of planting Cistanche tubulosa in Yellow River Delta.Methods:C. tubulosa to the wild Tmarix chinensis in Yellow River Delta was inoculated using trenching inoculation,then the inoculationrate and growth status of C.tubulosa was investigated.The seeds from the mature inflorescence was harvested and the seeds germination rate after pretreatment with fluoride were investigated.The content of echinacoside and verbascoside in the C. tubulosa was analyzed by means of chromatography.Results:These results indicated that C. tubulosa could ensure normal growth,flowering,fruiting,and complete its lifecycle in the Yellow River Delta region.The inoculation rate of C.tubulosa was 81.9%,seed germination rate was between 46~63%.The content of echinacoside and verbascoside together was 22.1%.Conclusion:This study successfully inoculated C. tubulosa to the wild T.chinensis in Yellow River Delta.The content of echinacoside and verbascoside meets the requirement of the Chinese Pharmacopoeia.
