Comportamento de linhagens de sorgo forrageiro submetidas a déficit hídrico sob condição controlada

Abstract: O objetivo deste trabalho foi avaliar os efeitos do estresse hídrico no estabelecimento, desenvolvimento e na taxa de sobrevivência de 11 linhagens de sorgo forrageiro em casa de vegetação. O delineamento experimental foi o de blocos ao acaso no arranjo de parcelas subdivididas no tempo, com cinco repetições. As unidades experimentais foram constituídas por recipientes de 250 L, onde foram colocados 187,9 kg de solo da classe textural areia franca. O estudo compreendeu dois períodos de estresse, e três irrigaç… Show more

“…Under soil water-stress conditions, sorghum can stunt its growth or decrease its metabolic activity and later, when water conditions improve, it resumes growth at rates that may be higher than those of plants that have not undergone water stress (Amaral et al, 2003). Insufficient water is considered one of the greatest worldwide limitations to agriculture because of its impact on species growth and development (Batista et al, 2008) and consequent reductions in relative water content, nitrate-reductase activity, proteins, ammonium, tissue nitrate and increased concentrations of amino acids (Souza et al, 2014).…”
