Sorghum (Sorghum bicolor (L.) Moench) is the fifth most important cereal crop of the world. In South America, it is grown mainly on acid soils, and its production on these soils as limited by deficient levels of available P, Ca, Mg, and micronutrients, and toxic levels of Al and Mn. A greenhouse experiment was undertaken to evaluate the genotype differences in sorghum for uptake (U), inhibition (lH), influx (IN) into roots, and transport (TR) to shoot for nutrients at three levels of soil. Al saturations (2,4,64%). Overal shoot nutrient U, IN, and TR showed a significant inverse correlation with soil Al saturation and shoot Al concentration, and a significant positive correlation with shoot and root dry weight. The nutrient uptake parameters differentiatedgenotypes into most and least efficient categories at various levels of soil Al saturation. The nutrient uptake parameters showed significant differences with respect to soil Al saturation, genotypes, and their interactions. In the currents study, Al tolerant genotypes recordes higher IN and TR for P, K, Ca, Mg, Zn, and Fe than Al-sensitive genotypes Therefore, these U, IN, and TR traits could be used in selection of sorghum plants adaptable to acid soils. Sorghum genotypes used in this study showed intraspecific genetic diversity in U, IN, and TR for essential nutrient, It was concluded that selection of acid tolerant genotypes and further breeding of acid (Al) tolerant sorghum cultivars are feasible. |
