Photosynthetic function of wheat genotypes with different donor-acceptor ratio in water deficiency

The article presents the results of studies of the intensity of photosynthesis of wheat genotypes at various donor-acceptor ratios. Field experiments were carried out in the optimal irrigation regime and under drought conditions, the object of research was wheat genotypes: Barakatli 95, Vugar, Garagylchyg 2 and Gyrmyzy bugda. An artificial change in the donor-acceptor ratios in the plant, in combination with environmental factors, including the effect of drought, has a certain effect on the intensity of photosynthesis. When exposed to drought, the intensity of photosynthesis naturally decreases in both leaves. The removal of one layer of leaves leads to an increase in the intensity of photosynthesis in the leaves of the other layer, and when half the ear is removed, on the contrary, a decrease in the intensity of photosynthesis is observed both in the 7th and 8th leaves.
