Root morphology and kinetics of Zn absorption by roots of common bean influenced by Zn status of the root environment

Understanding the kinetics of Zn absorption by roots and its effect on morphology this organ is relevant for improving crop management, but still poorly studied common beans. Therefore, an experiment was conducted in a hydroponic system with five initial concentrations (CZnI): 0.0; 1.0; 4.0; 16.0 48.0 µmol L-1. The installed plants at V3 stage development aliquots solution collected over 24 h. maximum rate (Vmax), Michaelis-Menten constant (Km) power (α) increased as function CZnI. minimum concentration estimated (Cmin) 0.0028 mg influx (Imax) higher CZnI, 16,0 Root length, root volume, content efficiency increase CZnI positively influenced kinetic parameters bean morphology, characteristics that favor improves overall plant nutrition, favoring agronomical biofortification practices other nutrients.
