Abstract : The bud inoculation test is presented here as an alternative to the belt spray method for comparisons between clones (budded plants or rooted cuttings). During the Workshop a leaf inoculation method, developed by M. Ducamp in Trinidad, was also presented. The leaf method associates the effect of basidiospore germination/ penetration and the phytotoxic effect of glycerol. However, subsequent work carried out with this method showed that it needs further development before it can be recommended in the project. The description of this method is not included in these Proceedings. (Résumé d'auteur)
