Abstract:
Astragalus membranaceus adventitious roots (AMARs) were used as the test material,the effects of total nitrogen content,NH+4∶NO-3 ratio and phosphate content on the biomass of adventitious roots and the accumulation of anthocyanin were studied by changing the composition of B5 medium.In order to get the best ratio of nitrogen and phosphorus.The results showed that when the total nitrogen concentration was 3.0 mmol·L-1,NH+4∶NO-3 ratio was 1.5∶1.5,PO3-4 concentration was 0.625 mmol·L-1,both biomass and content of ononin in AMARs reached the maximum,and each ononin content increased about 7,14,19 times compared with the initial medium,respectively.Therefore,the method was simple and reliable,and the results of proportioning lay a theoretical foundation for further production of anthocyanin in AMARs.
