Differences among Triticum dicoccum , T. monococcum and T. spelta in rate of nitrate uptake

Popis výsledku v původním jazyce

Three groups of wheat cultivars Triticum dicoccum , T. monococcum and T. spelta were grown in hydroponics at controlled conditions. At the age of 21 days wheat plants were analysed to determine their rate of nitrate uptake, the net NO3- uptake capacity and total nitrogen content. The rate of nitrate uptake varied from 2.7 (T. dicoccum) to 9.3 (T. monococcum) ?mol NO3-/g FW/h; in economically important species T. spelta it ranged between 3.1 ? 6.9 ?mol NO3-/g FW/h. In T. diccoccum and T. spelta these values represent about 80 ? 90% estimated Vmax. Both groups significantly differed from T. monococcum. This collection was characterized by the highest Vmax, its nitrate uptake rate per g fresh weight reached only 45 ? 67% Vmax. Within each group there werefound the intra-species differences. Nitrate uptake capacity of the individual species or varieties was significantly affected by differences in development of root system. These results were compared with registered cultivar T. aestivum
