Effect of MF3 (peptidyl-prolyl cis/trans isomerase) protein from Pseudomonas fluorescens on ex vitro adaptation and post-adaptation of hardy kiwi (Actinidia arguta Planch. ex Miq.) plants

Abstract

The effect of bacterial protein (peptidyl-prolyl cis/trans isomerase) in different concentrations on ex vitro adaptation and post-adaptation of Actinidia arguta Planch. ex Miq. plants of cultivar Geneva was investigated. The results indicating the growth-stimulating effect of MF3 protein were obtained, when applied at a concentration of 0.5 mg/mL, morphometric indices of above-ground plant development increased almost 2-fold compared to the control, and when used at a concentration of 0.1 mg/mL, there was a 1.8-fold increase in the root system compared to the control.
