Abstract:

A total of 38 fungal taxa were identified on senescent untreated and autoclaved Castanopsis fissa leaves during a 4-month study period. Seventy-six percent of the fungal genera found in this survey have not previously been recorded from Castanopsis. Frequency and time of occurrence of fungal taxa occurring on untreated senescent leaves were clustered into four groups when analyzed by cluster analysis, suggesting the replacement of microfungi in stages of succession on naturally senescent leaves. Autoclaved leaves revealed significantly different fungal communities, with only 26% of overlap with the natural ones and no clear patterns of replacement of fungal communities. Factors regulating the rates of decomposition are also discussed.Key words: Castanopsis, decomposition fungal ecology, fungal succession, microfungi.

Lors d'une étude d'une durée de 4 mois, un total de 38 taxa fongiques ont été identifiés sur des feuilles de Castanopsis fissa en sénescence, non traitées et autoclavées. Soixante-seize pour cent des genres fongiques trouvés lors de cette étude n'avaient pas été précédemment répertoriés pour Castanopsis. La fréquence et la temps d'apparition des taxa fongiques se trouvant sur les feuilles sénescentes non traitées ont été rassemblés en quatre groupes suivant une analyse typologique, suggérant un remplacement des micro-champignons par stades successifs, sur les feuilles naturellement sénescentes. Les feuilles autoclavées ont révélé un patron différent de communautés fongiques, présentant seulement 26 % de chevauchement avec les communautés naturelles, sans patron clair de remplacement des communautés fongiques. Nous discutons aussi des facteurs qui régulent les taux de décomposition.Mots clés : Castanopsis, écologie de la décomposition fongique, succession fongique, champignons microscopiques.[Traduit par la Rédaction]
