Pyrolysis-gas chromatography combined with simca pattern-recognition for classification of fruit-bodies of some ectomycorrhizal suillus species

In English Naturally grown fruit-bodies of Suillus luteus, S. bovinus and S. variegatus were subjected to Py-GC. The pyrograms obtained were statistically analysed and classified with a multivariate classification program (SIMCA). The class describing the S. bovinus pyrograms was significantly separated from both the S. luteus and the S. variegatus classes, while these two classes showed some over-lapping which was due to variation between different fruit-bodies within each species. The taxonomic significance of the statistical distances between the classes representing the species is uncertain.
