Study of priming for callose accumulation in Allium cepa during treatment with biotic inducers

The effect of preliminary treatment with inducers of resistance (salicylic and hexanoic acids) at the level of callose synthesis in cells of three onion cultivars have been studied. The ability of these inducers to increase the resistance of onion to pathogenic infections at low concentrations was shown. Using the method of spectrofluorimetry, we demonstrated that the treatment of onion scales with salicylic and hexanoic acids led to the priming of the reaction of callose accumulation.
