عنوان مقاله [English]
In order to investigate the effect of different levels of 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, effect of three levels of IBA (0, 2000 and 4000 mg/ ml) and in the second one effect of two strains of P. fluorescens (R5 and R64) on olive (Olea europaea cv. conservaliya) were investigated. 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 related to control, while the maximum phosphorus uptake was obtained in 4000 mg/ml IBA. The interaction effect of IBA and bacteria showed that in morphological characteristics and uptake and concentration of elements, maximum average were obtained in 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 of rooting is recommended.
