Abstract

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.
