Gaertn.) growth [Elektronische Daten] 1. Characterization of growth promoting and growth inhibiting bacterial strains [A. Probanza, J. Lucas, N. Acero, F. Gutierrez Mañero] The effects on plant growth of 27 bacterial strains (7 Pseudomonas and 20 Bacillus) isolated from the rhizosphere of a natural alder stand, were studied. The chosen bacteria were selected from the dominant genera found in that habitat in each season. These bacteria were grown in a complete culture medium, and removed (centrifuged and filtered) prior to testing on nodulated (N) and non-nodulated (NN) alder plants. Tests were made in order to determine their effects on the following biometric parameters: aerial surface (AS), aerial length (AL), number of leaves (NL) and total nitrogen (TN). Among the 20 Bacillus strain tested, three promoted growth; two were B. pumilus strains and one was B. licheniformis. Significant (p<0.05) increases in all biometric parameters were detected (163% on AS and 182% on AL). All 7 Pseudomonas fluorescens strains had a significant (p<0.05) negative influence on plants, evidenced by a decrease in the value of different parameters when compared to control values. The obvious effect of the assayed bacterial strains on alder growth drawn from our results should be considered as the starting point for a deeper study of the plant-rhizobacteria interaction, the final aim being to improve production of any forestry species, particularly that of Alnus glutinosa.
