The effect of plant growth promoting rhizobacteria on plant development, yield and fruit quality of raspberry (Rubus idaeus L.) cultivar “heritage”

The present study was conducted at research field of Agriculture Faculty of Selçuk University in 2014-2015. The effects of plant growth promoting rhizobacteria inoculated “Heritage” raspberry (Rubus idaeus L.) plant roots on plant growth (shoot length, sucker number, trunk diameter, leaf area, root length, fresh and dry shoot weight, fresh and dry root weight), yield (yield, fruit number, fruit weight) and criteria of fruit quality (pH, total soluble solids, total acidity, ascorbic acid content and anthocyanin content) were investigated. The best result of cane length was obtained from 637Ca treatment (70,20cm). 637Ca treatment with 6.42 suckers and MFDCA-2 with 6.85 suckers were the best result calculated. In terms of yield, 637Ca application with 304.65g/plant showed the best performance. The MFDCa-2 and M3 bacteria strains has more effective than others for fruit quality criteria. As a result, the plant growth-promoting Rhizobacteria (PGPR) treatments could be offer an economic and beneficial means to increased plant growth, yield and fruit quality.
