Lokal olarak izole edilen fosfat çözücü Pseudomonas aeruginosa IBP26’ nın nohut fidelerinin büyüme parametreleri üzerine etkisi

Abstract

This work was conducted to examine the effect of locally isolated phosphate-solubilizing bacteria on the growth parameters of chickpea seedling cultivated in pots containing Ca3(PO4)2 (tricalcium phosphate). Among the isolated strains, the highest phosphate-solubilizing activity in the broth medium was observed for the isolate IBP26. Similarly, in the greenhouse study, the same isolate was determined to cause maximum increases in growth parameters (shoot and root length, total biomass, phosphorus, total sugar, and protein contents) of chickpea plants in the presence of Ca3(PO4)2. The isolate IBP26 was identified as Pseudomonas aeruginosa (GenBank accession number: MW092004). Experiments demonstrated that the application of the bacterium alone in the absence of Ca3(PO4)2 or the application of Ca3(PO4)2 alone in the absence of bacterium did not cause significant change in growth parameters of the chickpea plants, and that the desired increases in the growth parameters of these plants could be achieved by the co-application of bacterium and Ca3(PO4)2.
