Effects of Plant Growth Promoting Rhizobacteria on Growth, Yield and Fruit Quality of Pomegranate (Punica granatum L.)

Abstract

This study was carried out in a commercial pomegranate garden in Denizli, in 2017-2018 in order to determine the effects of Pseudomonas sp. HV 5 and Micrococcus luteus GC- subgroup B MFDV3 bacterial strains, which are potentially capable of improving plant yield and development, on plant growth, yield and quality. The effects of bacterial application on shoot diameter, fruit width, fruit size, fruit juice content, pH, acidity and yield per tree were statistically in significant but the effects on fruit weight, fruit volume and fruit juice C vitamins were found to be significant. Concomitant use of HV5 and MFDV3 bacteria resulted in increased fruit weight, volume, and amount of vitamin C in fruit juice compared to control. According to the results of the research, it was concluded that the bacterial strains used had a positive effect on fruit juice and vitamin C only, so that different application forms and doses should be tested.
