| Popis: | In order to investigate the effect of different levels of IBA and strains of Pseudomonas fluorescens bacteria, an experiment was conducted as factorial with completely randomized design containing two factors and three replications. In the first factor, the effect of three levels of IBA (0, 2000, and 4000 mg/ ml) and in the second one, the effect of two strains of P. fluorescens (R5 and R64) were investigated on olive (Olea europaea cv. conservaliya). Results showed that bacterial inoculation with R5 strains increased shoot and root dry weight, total dry weight, nitrogen concentration, and phosphorus uptake compared to control, but there was no significant difference between R5 and R64 strains in terms of total chlorophyll. The 2000 mg/ml IBA also increased shoot and root dry weight, nitrogen concentration, total chlorophyll, and total dry weight compared to control while the maximum phosphorus uptake was obtained at 4000 mg/ml IBA. The interaction of effects of IBA and bacteria in morphological characteristics and uptake and concentration of elements showed that maximum average were obtained at 2000 mg/ml IBA and R5 strain treatment. According to the obtained results, the application of both of 2000 mg/ml IBA and R5 strain for improvement in rooting is recommended. |
