In vitro tissue culture with immature infl orescence in eight genotypes of Miscanthus lutarioriparius was performed to determine their callus induction rates, differentiation rates and stem chemical component contents in this study. The results indicated that there were signifi cant differences in callus induction rates and differentiation rates among the genotypes, genotypes A4 and A6 grew at a callus induction rate of 97.5%(the highest) and 94.2% and at a differentiation rate of 91.8%(the highest) and 83....
