English abstract
Field and laboratory studies were conducted in 1990 and 1991 to determine the concentrations of total nonstructural carbohydrates (TNC), crude protein, cellulose, hemicellulose, lignin and ether extract partitioned in the leaf and stover of sorghum grown in a saline soil (EC = 11.8 dSm-1). Twenty throe sorghum cultivars comprising 10 female lines, 6 male lines and 7 forage lines were used. TNC was uniformly dstributed in the leaf and stover portions. Significantly higher concentrations of cellulose and lignin were partitioned to the stover portions than the leaf, but the leaf contained larger amounts of hemicellulose and ether extract than the stover. Although, based on TNC contents. some of the sorghum types have a potential for methanogenesis, the competing demand as anımal feed also needs to be considered.
