Resumo: | Sorghum [Sorghum bicolor (L.) Moench] crop is distinguished from other crops for its tolerance to both water deficit and excess soil moisture, under very dry and/or very hot environmental situations in which the productivity of other cereals becomes uneconomical. This work was conducted to evaluate the effects of irrigation on root conformation at the initial development phase of sweet sorghum. So, BRS 501 cv. was subjected to four irrigation levels based on 80%, 60%, 40% and 20% of the field capacity (CC). The decreased availability of water in the soil negatively affected the majority of the characteristics under evaluation except for the relationship between the root system and the aerial part (SR/PA), average root diameter (DMR) and specific root area (ARE). We concluded that the growth of sweet sorghum plants under evaluation is sensible to the decrease of water in the soil, as it is affected by low water availability. This methodology, common to other crops, can be used for saccharine sorghum in order to establish hydric availabilities in new experiments to discriminate the drought-tolerant cultivars. |

A cultura do sorgo [Sorghum bicolor (L.) Moench] destaca-se das demais por tolerar tanto o deficit hídrico como o excesso de umidade no solo, em situações ambientais muito secas e/ou muito quentes, nas quais a produtividade de outros cereais torna-se antieconômica. Este trabalho objetivou avaliar os efeitos da irrigação na conformação radicular na fase inicial de desenvolvimento do sorgo sacarino. Nesse propósito, foi utilizada a cultivar BRS 501 submetida a quatro níveis de irrigação que se basearam em 80%, 60%, 40% e 20% da capacidade de campo (CC). A diminuição na disponibilidade de água no solo influenciou negativamente a maioria das características avaliadas com exceção da relação entre o sistema radicular e a parte aérea (SR/PA), diâmetro médio de raiz (DMR) e área radicular específica (ARE). Conclui-se que o crescimento das plantas de sorgo sacarino é sensível à diminuição de água no solo, sendo afetado pela baixa disponibilidade hídrica. A metodologia utilizada, comum a outras culturas, adequa-se ao sorgo sacarino para estabelecer disponibilidades hídricas em estudos com a finalidade de discriminar cultivares tolerantes à seca.Instituto Federal de Educação, Ciência e Tecnologia Fluminense2016-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://editoraessentia.iff.edu.br/index.php/vertices/article/view/590810.19180/1809-2667.v18n32016p135-145Revista Vértices; Vol. 18 No. 3 (2016): Sept./Dec.; 135-145Revista Vértices; Vol. 18 Núm. 3 (2016): sept./dic.; 135-145Revista Vértices; v. 18 n. 3 (2016): set./dez.; 135-1451809-26671415-2843reponame:Vértices (Campos dos Goitacazes.
