Maize genotypes with contrasting genetic variability have different yield potential. This distinct yield potential may be partially caused by differences in the root system morphology or in the nutrient uptake kinetics parameters. This study aimed to assess such morphological and physiological plant attributes of three maize genotypes with different genetic bases. A single-cross hybrid (P32R21), a double-cross hybrid (Traktor) and an open-pollinated variety (BRS Planalto) were studied. The uptake kinetics parameters (maximum influx – Imax, Michaelis-Mentem constant – Km, and […]
