Abstract

The aim of this study was to investigate the effectiveness of isolates capable of producing IAA and utilizing ACC as the sole source of nitrogen on growth of pistachio seedlings. In the present study, based on fluorescent properties of isolates in KING B MEDIUM, 52 colonies of fluorescent pseudomonad were randomly isolated from the rhizosphere of pistachio seedlings and then purified. These strains were identified according to the microscopic, physiological, and biochemical characteristics tests related to species determination. Study results showed that 49 of the 52 isolates belonged to Pseudomonas fluorescens species and, due to the lack of conformity with the characteristics in the BERGEY BOOK, three isolates were identified as Pseudomonas sp. Then, isolates were evaluated for the ability to produce IAA and utilize ACC. The results indicated that all the strains were able to produce IAA and 62% of which were able toutilizeACCas the sole sources of nitrogen. In a greenhouse experiment, the effectiveness of the six isolates that were able to utilize ACC and produce different amounts of IAA were tested on the pistachio seedlings. The results showed that application of most of the strains significantly increased leaf number, leaf area, and shoot fresh and dry weight of pistachio seedlings.
