| description | Azotobacter chroococcum is a rhizosphere bacterium that has been used for decades as a plant growth stimulator in a wide range of crops. It is able to fix nitrogen and produce growth promoting substances. In the present work we show the results to determine the effectiveness of the application of different strains of A. chroococccum on acclimatization of in vitro pineapple plants. Six strains were evaluated from the strain collection of INIFAT. For its multiplication and application the Cuban standard for the production of A. chroococcum was used. We evaluated the following indicators: survival, plant height, leaf number, root length, fresh weight and dry weight. Strain INIFAT 5 proved to be the greatest stimulation occurred in most of the variables analyzed and it was selected for further study as the most effective strain for acclimatization of in vitro pineapple plants.
Key words: Ananas comosus L., biofertilizer, plant growth promotion bacteria. |
