“…We also observed a higher number of V. album colonies associated with more south facing stands. This result seems to be in line with the higher inoculation success obtained by F rochot and L anier (1980) under experimental conditions on south and south‐east aspects of the tree. Successful germination of V. album seeds depends on both light and high enough temperatures from the very beginning (Z uber 2004).…”

In the last two decades, stand decline and increased mortality has affected silver fir (Abies alba) forests in the Spanish Pyrenees. Simultaneously severe occurrences of the root rot fungus Heterobasidion annosum s.l. and of the mistletoe Viscum album have been reported. We aimed to improve the understanding of the epidemiology of both pathogens in our region. All H. annosum isolates found on silver fir were typed as H. abietinum. H. abietinum was more frequently observed where cuttings had targeted fir trees rather than other species. H. abietinum fruiting bodies were observed in the most recently cut stumps. V. album was more abundant on more dominant fir trees, and in southern aspect stands. The number of V. album colonies in the stand correlated (R 2 = 0.40) with silver fir mortality. Stands with a high level of V. album infection tended to have a smaller percentage of basal area in species other than silver fir, and they tended to be located on more south-facing slopes. H. abietinum was widespread in silver fir forests of the Pyrenees. Our data suggest that, in the Pyrenees, the observed H. abietinum incidence may represent a combination of both primary and secondary spread of the pathogen. Favouring mixed forests should be tested as a potential control method for V. album. The correlation between silver fir mortality and V. album infection warrants further study, as the observed tree mortality could have occurred due to other factors than V. album, such as drought damage.

“…Les phytohormones utilisées (2,4-D ; 2,4-MCPB ; 2,4, 5-T) ou le sulfate de cuivre sont pulvérisés sur le systè-me foliaire du Gui ou injectés dans des entailles pratiquées à la base du tronc de l'hô-te. Dans les meilleurs cas, la partie aérienne du Gui dégénère dans les six mois et aucune régénération n'est observée dans les cinq années qui :mivent le traitement (Froc hot et Delabraze, 1979). Cette dernière observation tend à prouver que le système endophytique du Gui a été détruit.…”

“…Actuellement, les chercheurs du C.l\.R.F. (Centre National de la Recherche Forestière) de Nancy considèrent qu'un contrôle chimique du Gui est envisageable, aussi bien sur Sapin (Frochot et Delabraze, 1979) que sur Peuplier (Frochot et coll., 1983). Cependant, une meilleure connaissance de la physiologie du parasite est encore nécessaire afin de déterminer la meilleure période de traitement durant 1 'année.…”

European mistletoe (Viscum album L.) is a hemiparasitic plant growing on different host trees. According to host specifity three different races can be distinguished. The plant is dioecious with very reduced male and female flowers. The life cycle of V. album is described starting from seed germination to the development of the leaves. The parasitism affords special adaptation to mineral nutrition.
