Název v původním jazyce

Nitrate uptake and nitrogen allocation in wheat as affected by exogenous cytokinins.

Popis výsledku v původním jazyce

Growing wheat plant in high nitrogen (HN) and low nitrogen (LN) nutrient solutions had little effect on NO3 uptake rates and the overall plant uptake capacity from the stage of intensive stem elongation to anthesis. The application of cytokinin to LN plants increased their nitrate uptake by 21-35 %. Such stimulation was not observed when cytokinin was applied to HN plants. The nitrate uptake as well as plant uptake capacity sharply declined after anthesis. Application of cytokinin significantly reduced this decline. The reduced nitrate supply to LN plants was associated with proportional lowering of NO3 content and NR activity in leaves. Application of cytokinin had little effect on NR activity and NO3 levels in leaves of HN plants. However, it significantly increased NR activity in flag leaves of LN plants after anthesis.
