Bacterization effect of seeds on the growth of Cedrus atlantica Manetti plants

The beneficial effect of five rhizobacterial strains on the growth of Cedrus atlantica plants was evaluated at forest nursery before out-planting. The obtained results showed a significant effect of bacterial strains on cedar seedlings growth and only Pseudomonas fluorescens A6RI and TGI252 significantly increased stem length, neck diameter, root dry weight and number of root tips. It will allow us to adapt this technology for the production of quality plants.
