Abstract
Elicitation, also known as biostimulation, is a method of inducing plant metabolism to stimulate systemic resistance. Elicitors induce controlled plant stress by inducing the action of antioxidant enzymes and the accumulation of secondary metabolites. The enhancement of plant resistance to pathogens is mainly related to the production of reactive oxygen species, sealing of cellular structures, synthesis of immune proteins and peptides, including numerous defense enzymes. A study of the effects of elicitors on yield and health of spring wheat showed that the highest yield was obtained after the application of deproteinised insect chitin and the lowest after the use of potassium iodide. Sites with sodium hypochlorite had significantly lower yield parameters. For crop residue weight, the highest value was observed after the application of hydrogen peroxide. The highest harvest index was recorded after the application of deproteinised insect chitin, which was 3% higher than the control treatment. The application of elicitors did not affect the weight of one thousand grains. The application of elicitors on wheat plants showed significant variation in susceptibility to downy mildew disease. Cereal stem base rot occurred at the highest severity on sites where salicylic acid and phenylalanine were applied. For cereal stem breakage, the highest infestation rates were in plots where deproteinised chitin was used. The lowest infestation rates were recorded for hydrogen peroxide. The plant tested had the lowest infestation by brown rust, and the elicitors used significantly differentiated this value. The highest infestation was observed when cricket flour and deproteinised chitin were used. Among leaf diseases, the most severe infestation was observed for wheat leaf stripe septoria. The most infested sites were those where potassium iodide was applied as an elicitor. The lowest infestation rate was observed with the application of hydrogen peroxide, but showed no significant differences. In conclusion, the use of elicitors affected the yield and health of spring wheat. Deproteinised insect chitin showed high biostimulatory value and had the greatest effect on yield. Hydrogen peroxide, on the other hand, influenced the lowest disease infection rates, indicating its strong fungicidal properties.
