Abstract
The studing the efficiency of new magnesium-containing fertilizer “AktiMax” use for priming soft winter wheat seeds of the “Skipetr” variety. The effect of the fertilizer is compared with the negative (no fertilizer) and positive (“Novosil”) controls. During the study, the optimal concentration 2.6 ml/l of the solution for processing by the selected method is found, which is equivalent to 20% of the recommended by the manufacturer (13 ml/l). At treating with a solution of this concentration, a slight decrease in seed germination is observed, and growth parameter records taken after 7 days showed an increase in leaf length by 15–20%. A slight decrease in the number of roots (by 10%) and branching of the root system is observed, which is presumably due to the availability of the fertilizer components. The effect fertilizer on the photosynthetic apparatus, carbon dioxide assimilation and transpiration rate when use in a range of concentrations is studied. On average, the transpiration activity increased by 2 times in the variant with the working concentration and by 1.8 times in the variant with one fifth of the working concentration. A slight increase in the efficiency of non-photochemical fluorescence quenching is revealed in plants at the “AktiMax” application. The efficiency of seed priming method use to stimulate the rate of winter wheat development is demonstrated that leads to reduction of unfavorable outcomes risks.
