Abstract In laboratory experiments with resting and germinated seeds of spring wheat, the effect various biological preparations on activity catalase isoforms was studied. experiments, determined at pH = 5.5, 7.0, 8.0 using a phosphate buffer system (1/15 M buffer). The enzyme in dormant wheat grain that underwent post-harvest ripening during germination third, fifth, seventh days method based ...

Abstract At present, plant biostimulating adaptogens used in the process of growing a wide range cultivated plants are artificial analogs natural stimulants, chemical composition which contains phytohormones, amino acids and vitamin complex, enhance growth development root system by several times. The effectiveness these agents is explained creation mutually beneficial symbiosis mycelium mycorr...

Abrief review has been made of selected work in bioorganic chemistry carried out in the Soviet Union in the past decade. Most consideration has been given to the chemistry of peptide and protein substances, including structural, synthetic, stereochemical and structure—functional studies. The most importantresults have been touched upon, obtained from chemical study of nucleic acids, carbohydrat...
