摘要: Alternative biomass sources must be developed if the United States is to meet goal in U.S. Energy Security Act of 2007 derive 30% its petroleum from renewable sources, and several different crops are currently development. Sorghum [Sorghum bicolor (L.) Moench] one such crop that will an important feedstock source for biofuel production. As composition influences productivity, there exists a need understand range observed within crop. The this research was assess dietary fiber types sorghums. A total 152 sorghum samples were divided into four end-use sorghum: biomass, forage, sorghum-sudangrass, sweet. These analyzed chemically using analysis performed at National Renewable Laboratory published protocols. Significant variation among groups detected glucan ash. Positive highly significant correlations between structural carbohydrates sweet sorghums while many these negative or not forage sorghum-sudangrass types. In addition, wide present each group indicating potential manipulatemore » crop.« less
