Composição bromatológica e parâmetros físicos de grãos de sorgo com diferentes texturas do endosperma

Abstract

Chemical composition and physical parameters of 33 sorghum grain genotypes with different endosperm textures were obtained. Dry matter mean of genotypes was 88.77%; crude protein varied from 9.85% to 18.28%; starch varied from 62.07% to 78.74%; ether extract from 1.76% to 3.68%; crude fibra from 0.35% to 6.60%. Tannins were observed only for BR 305, SHS 600 and A 9904. The 1,000 grains weight varied from 12.58g for CMSXS 214 to 27,18g for A 9904. Density values varied from 1.40g/cm3 for texiota 5 to 1.50g/cm3 for SC 283. The vitreosity values varied from 1.10 to SC 283 to 4.20 for Early Hegari. Great variability for chemical and physical parameters of sorghum genotypes was observed.
