| Echinolaena inflexa (Poir.) Chase is a native C3 grass species with high biomass production and abundance in the cerrado comparable to Melinis minutiflora Beauv., a C4 forage grass of African origin, widespread in the cerrado, displacing some native herbaceous species. These species accumulate mainly starch, differently of Lolium multiflorum Lam. ssp. italicum Beck cv. Lema (ryegrass), a C3 temperate forage grass that accumulates fructans as the major storage carbohydrate in the vegetative tissues. In the present study, we analyzed diurnal variations in the content and composition of non-structural carbohydrates (NSC) in the aerial vegetative parts of the three species. Results showed similarity in water-soluble carbohydrates (WSC) and starch contents... |
