          Abstract

          O presente trabalho objetivou avaliar a influência do sombreamento sobre o desempenho de cultivares de sorgo granífero. O ensaio foi realizado em casa-de-vegetação, utilizando-se delineamento inteiramente casualisado, em esquema fatorial 4 x 2, correspondendo aos quatro híbridos de sorgo granífero (DKB 599, AG 1040, BRS 308 e AG 1040) submetidos a pleno sol e sombreado, com três repetições. Determinou-se a altura de planta, área foliar, matéria seca das folhas, caule, raízes e panícula, além do comprimento do pendão e da panícula. Os resultados obtidos permitiram constatar que o ambiente sombreado proporcionou maior altura de plantas de sorgo, porém menores valores de área foliar. A redução na luminosidade proporcionou ainda maior acúmulo de massa seca de folhas e caule de todas as cultivares avaliadas. Somente a cultivar BRS 308 apresentou estabilidade produtiva indiferente do ambiente cultivado.

          This study aimed to evaluate the effects of shading on the performance of cultivars of grain sorghum. The test was conducted in a greenhouse using randomized design in a 4 x 2 factorial scheme, corresponding to the four hybrids of grain sorghum (DKB 599, AG 1040, AG 308, BRS 1040) submitted to a condition with and without shade, all treatments with three replications. We evaluated plant height, leaf area, dry matter of leaves, stems, roots, panicles, and the length of the tassel and panicle. The results show that the shaded environment led to greater height of plant sorghum, but lower values of leaf area. The reduction in brightness provided even greater accumulation of dry mass of leaves and stems of all evaluated cultivar. The BRS 308 showed stable production regardless of growth environment.
