Effect of elevated CO2 and nitrogen on the mineral composition of durum wheat
2006
Kostadinova, S. | Panajotova, G.
The effect of elevated CO2 concentration and nitrogen on the nutrients content (nitrogen, phosphorus, potassium, calcium, manganese) on the aboveground organs of durum wheat variety Vazhod at anthesis was studied. The investigation was carried out under controlled conditions. It was established that the elevated nitrogen and CO2 concentration increased the plants' dry mass at anthesis. The elevated CO2 concentration of the atmosphere had a week effect on nitrogen, phosphorus and magnesium content in the flag leaf. The highest content of manganese and iron in the aboveground organs of durum wheat was established in plants grown under elevated CO2 concentration and nitrogen fertilization.
