Treść
The use of phosphate solubilizing bacteria as inoculants may increase the concentration of plant-availablephosphorus in soil. Among soil microorganisms, bacteria from the genus Pseudomonas have receivedconsiderable attention as plant growth promoters. A phosphate solubilizing bacterium isolated fromnon-rhizosphere soil collected in Central Poland, was identified as Pseudomonas luteola BN0834 on thebasis of biochemical methods and 16SrDNA sequence analysis. P. luteola strain BN08-34 was tested for:solubilization of inorganic and organic compounds of phosphorus (calcium phosphate, zinc phosphate,hydroxyapatite and calcium phytate); indole acetic acid (IAA), siderophore production and biosurfactantproduction; and the ability to grow on a medium without nitrogen added. Young apple trees, cultivarLigol (rootstock M26), were grown in a pot-house for 14 weeks in pots filled with nonsterilized soil,classified as a sandy loam. The P. luteola BN0834 was introduced into the soil in a number equal to thenumber of native phosphate solubilizing microorganisms (PSM) (P. luteola) in soil or in a number tentimes higher than the number of native PSM in soil (P. luteola × 10). Shoot numbers; average and totalshoot lengths; contents of P, K, Mg and Ca in plant material; contents of available P, K and total Mgin non-rhizosphere soil, changes in the number of cfu (colony forming units) of microorganisms (PSM,cophiotrophs, oligotrophs and fungi) in non-rhizosphere soil and in the rhizosphere of the apple treeswere studied. When the higher number of P. luteola BN0834 was introduced into soil without a mineralfertilizer added near the surface of the roots, positive correlations were found between the number ofPSM in the apple tree rhizosphere and the content of available P in non-rhizosphere soil and also betweenthe number of PSM in the apple tree rhizosphere and the amount of P, K and Ca in plant leaves. The highesttotal shoot length was also obtained from P. luteola × 10 application.
