Abstract

Miscanthus is a C4 perennial energy crop distributed in various regions of China. Miscanthus sinensis has a high potential for biomass production, great adaptability to marginal land and tolerance to stress environmental. It's very important for the production and development of biofuel to review both the morphological and geographical traits on yield. However, the relevance of biomass yield and the geographical position of habitat are still not well known. In the present study, investigations of heading date, plant height, stem number and dry biomass per plant were carried out to calculate the influence of the morphological traits on yield. The investigation was based on 327 Miscanthus sinensis accessions collected from 21 provinces from all over China. The analysis was carried out on the basis of the two-year field experiment. The data for the second year was used to perform the analysis of variance and regression. Statistical data analysis was also performed on the variation of the biomass and morphological traits over successive period of study. The results showed that the growth included plant height and stem number in the following year was much better than the first year, particularly the biomass. Regression analysis revealed that latitude, plant height, and stem number were the key morphological traits that influence the biomass production. Also, heading date and elevation were found to be highly correlated to yield structure. These results demonstrated that the growth and yield were strongly influenced by geographical location, and apart from morphological traits, geographical traits were important factors that affect biomass.
