The article presents the data of laboratory results on study effect phytoregulators changes in activity peroxidase enzyme isoforms dry seeds malting barley and during their germination. It was found that use grains increases isoforms.

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 determining amount hydrogen peroxide dissolved under action enzyme, subsequent titration remaining...

Abstract In the conducted studies, moorphological and physiological properties of nodule bacteria lupine were studied. Lupine plants grown under conditions a microfield experiment on typical medium loamy urban soil. study, pure culture Bradyrhizobium lupini was isolated. Then, morphological cells chemical composition cell membranes determined. The acid resistance also determined, as well ratio to antibiotics. All studies carried out according generally accepted methods. results research...
