A study of the potential for developing plant growth stimulants based on salicylic acid salts and complexes

Abstract

In recent years, research has intensified towards the development of environmentally safe, efficient, and selective plant growth stimulants. It is known that salicylic acid plays an important role in regulating a number of physiological processes in plants, including seed germination, root and stem growth, leaf surface expansion, photosynthesis intensity, and activation of stress defense mechanisms. The main objective of this study is to synthesize monobasic salicylic acid salts and complexes, confirm their structural properties by spectral analysis methods, and evaluate their plant growth-stimulating potential. Aqueous solutions of salicylic acid salts and complexes synthesized in laboratory conditions at different concentrations (0.001% and 0.0001%) were prepared and their effect on the germination of corn (Zea mays L.) seeds was studied. The results show that the germination of corn seeds varies depending on the concentration of different salts and complexes of salicylic acid. The highest germination was observed in 0.0001% salicylic acid solution - 18 seeds and in 0.0001% triethanolamine complex of salicylic acid - 17 seeds. The highest stem length - 5.30 cm was obtained with 0.0001% isobutylamine complex of salicylic acid.
