Innovative plant growth regulators of a number of butanamide in agriculture
Carried out the synthesis of substituted analogues of the synthetic plant hormone, indolebutyric (indolylmethane) acid - politimester amino-hydroxybutanone, their salts and derivatives. The obtained compounds were studied on poststimulus activity on seeds of winter wheat, spring barley, millet. It is established that substances tested at concentrations with a mass fraction of 0.01 and 0.0001% exhibit the properties of activators of germination of seeds. Substituted amides of 3-alkyl - and dialkylamino-4-hydroxybutanoic acid or their salts have a high growth-stimulating activity that allows to recommend them as tools for improving sowing qualities of seeds. Of the studied compounds increases the resistance of seedlings to water stress.
