Abstract

It has been years that AZOSPIRILLUM is known to promote plant growth. Phytohormone (especially AUXIN) production has the most important role in increasing the yield of inoculated plants. According to this, 60 strains of this genus were isolated, identified, and purified. This ability was evaluated in both qualitative and quantitative assays using colorimetric method and the effects of superior isolate on SWEET CORN were measured. Results revealed that the abundance and probability of the bacteria isolation is low and 17%. About 31.2% and 100% of AZOSPIRILLUM strains were capable of producing IAA in QUALITATIVE AND QUANTITATIVE METHODS respectively. In greenhouse experiment, bacteria treatments had significant effects on corn fresh weight, total dry weight, root dry weight and total nitrogen and phosphorus content of the plant. This was considered to be as the result of more lateral root formation which enhances nutrition uptake. In conclusion, the green house results in respect to in vitro achievements show that fortunately it can be claimed that bacteria of the genus AZOSPIRILLUM can be used widely for not only strategic gramineous plants like: corn, wheat, barely etc. but also for other useful plants.
