THE INFLUENCE OF SODIUM SALTS OF 3-(3-BENZOXAZOLONYL)- AND 3-(6-NITRO-3-BENZOXAZOLONYL)PROPANOIC ACIDS ON THE GROWTH AND BIOMASS ENERGY PARAMETERS OF DACTYLIS GRASS (DACTYLIS GLOMERATA L.)

On analyzing the study results, it was found that sodium salts of 3-(3-benzoxazolonyl)propanoic acid stimulate dactylis grass (Dactylis glomerata L.) growth, accelerate photosynthesis. The biomass and calorific capacity of dactylis grass have increased when solutions of this salt had been used. The investigation revealed that the amount of dry material of dactylis grass was biggest when seeds had been treated with this salt solutions (concentrations 50 mg/l and 75 mg/l). The amount of dry material increased by 10 % on average in comparison with the control sample. The calorific capacity of dactylis grass was high and equal to birch wood combustion heat. The other analyzed compound – sodium salt of 3-(6-nitro-3-benzoxazolonyl)propanoic acid – increased carbon and hydrogen content, which determines the higher combustion heat, reduced ash content of plants, and a decreased melting point of ash.
