Titre espagnol : El injerto de la Guayaba (Psidium guajava) en el Cas (P. friedrichsthalianum) protege contra la sensibilidad al nematodo (Meloidogyne mayaguensis)

Abstract : In Martinique, guava cultivation is now made difficult by the arrival of the new pathogen Meloidogyne mayaguensis in the orchard soil. The current varieties (Psidium guajava) are very sensitive to this nematode and the tree declines when infested. In 1999, we introduced from Costa Rica a rootstock tolerant to this nematode. The association of this new species (Psidium friedrichsthalianum) with the current guava varieties does not show any symptom of incompatibility. Grafting technique is under trial to improve grafting percentage success. Field experimentations are developed to assess the efficiency of this association on the long term. Agronomic evaluation of guava grafted onto Cas is in progress with producers to test durability of tolerance, tree growth, productivity and fruit quality. First results are expected between 3 to 5 years. Cultural practices (tree density, pruning) will be adapted. [résumé d'auteur]
