摘要
Investigate the influence of culture media to growth and flavonol glycoside synthesis of calli introduced from seedling of \%Ginkgo biloba\%. 6 cell lines were selected from calli by hypoxia stress. Among these cell lines the best one TZ\|1 which growth index was 4.12 and the flavonol glycoside content was 1.25% in dried cell which was enhanced 257.1% compared with callus. The stability in subcultures was investigated: The average content of flavonol glycoside was 1.25% in dried cells and the growth index was 3.99 during 6 subcultures. Which variation coefficient was separately 0.065 and 0.048. The results show that hypoxia stress is a efficient method to select suspension cell line of higher productivity of flavonol glycoside.
