STATUS AND ACTIVITY OF THE PHOTOSYNTHETIC APPARATUS OF WHEAT PLANTS AFFECTED BY PHYTOMYCOPLASMOSES WITH PHYTOHORMONES FOLIAR TREATMENT

Inhibitory effect of Acholeplasma laidlawii var. granulum strain 118 on the photosynthetic apparatus and its activity was showed. It was established that foliar treatment by plant hormones ? kinetin (0.05 %) (mostly) and IAA (0.02 %) (less) modulates the plant immunity of plant-host through activation of pigment synthesis, increasing the efficiency of the photochemistry of photosystem II, a balanced increase of photochemical fluorescence quenching, whereby products of photosynthesis are used for the maintenance of the plant biosynthetic requirements.
