Phytochemical investigation of the needles of Abies nebrodensis (Lojac.) Mattei
2019
Abies nebrodensis (Lojac.) Mattei (Pinaceae) is a species living in a very small population only in a confined area of Sicily. In this study, the dichloromethane extract of the leaves was analyzed. Apart from three already known metabolites namely dehydroabietic acid; maltol; and rheosmin, previously detected in other species of Abies, a lanostane derivative was isolated. Its chemical structure was elucidated by means of extensive spectroscopic methods.
Survival, Growth and Mycorrhization of Containerised Pinus sylvestris and Picea abies Seedlings of Different Provenances Outplanted in a Forest Clear…

Abstract We studied field performance of containerised Pinus sylvestris and Picea abies seedlings of different provenances. Shoot height, needle chemical composition, root collar diameter, root mycorrhization and mycorrhizal species composition were evaluated after four growing seasons following outplanting. The results showed that in general spruce had better survival than pine. Ectomycorrhizas on spruce were dominated by Wilcoxina, Amphinema and Tylospora, while on pine — by Suillus and Thelephora species. Spruce and pine showing best growth rates were colonised by ectomycorrhizal fungus Amphinema sp. In conclusion, the results demonstrated that forest nursery practices as well as provena…
