Comparison of nitrate uptake and utilization in Triticum aestivum L. and Triticum dicoccum Schrank
Original language description
The aim of this work was to find out the differences in nitrate uptake and utilization by comparing the Vmax and Km uptake parameters characterizing the high-affinity uptake system in six modern spring cultivars of bread wheat and two cultivars of emmer wheat. The nutrient solution contained 300 µM N as nitrate. At the age of three weeks the net rate of nitrate uptake was measured in depletion experiments and it was expressed as mol. g-1 FW. h-1. Assessment of cultivars differences in terms of ability to absorb nutrients from the environment by determining the kinetic parameters of uptake systems could be used as a criterion in the selection and evaluation of breeding material. This applies provided that plants grown under precisely defined conditions are compared with each other. A suitable genetic source would be cultivars or species with lower Km, higher Vmax and higher R/S ratio.
