ROLE OF PRIESTIA MEGATERIUM AND PANATOEA AGGLOMERANS STRAINS IN ROOT PRODUCTION OF VITIS VENEFERA PLANT CUTINGS
Abstract
Strains of Priestia megaterium and Panatoea agglomerans were found to root and develop vegetative organs on Vitis venefera cuttings. These two strains were diluted at different concentrations and root formation was observed on the grapevine plant over a period of 40 days. When rooting cuttings, the number of roots was 25% compared to the control in a bacterial suspension at a concentration of 1/10. In a suspension diluted in a ratio of 1/50, 70% of the number of roots and the development of vegetative organs were observed. It has been shown that the number of roots in a suspension with a ratio of 1/100 is 100%; the growth of additional lateral roots, leaf blades and shoots on grape cuttings has been studied and analyzed.
