THE STIMULATING EFFECT OF SOME OF THE NEW 4-NITROBENZOIC ACID'S SALTS ON WHEAT CROP PRODUCTION

摘要

It is known that the chemicals with auxin-like activity have in their molecule at least an aromatic nucleus and a carboxylic group or its functional derivatives. Starting from this point of view, the new salts of 4-nitrpbenzoic acid with different ethanolamines were synthesized, characterized and tested. The present work studies the influence of the five new salts on the production of the wheat-Alex" cultivar. The experiment was carried out in the experimental fields, using six variants in triplicate, the concentration of the tested compounds being 100 ppm. Using these compounds an increase by 17-38% in the wheat production was obtained.
