Quali sono le specie arboree a rapido accrescimento per la Sicilia?
2018
A dispetto dell’uso diffuso massiccio della locuzione “specie a rapido accrescimento”, riferita a specie utilizzate per la produzione di biomassa, mancano ad oggi riferimenti certi che servano a definire le suddette specie. Si consideri, inoltre, che la locuzione è utilizzata, oltre che in articoli e testi tecnici, anche in testi che hanno carattere applicativo e/o costituiscono norme di riferimento come, ad esempio, le misure dei Piani di Sviluppo Rurale. Una definizione ormai datata della FAO (1967), riferita ai paesi in via di sviluppo, riporta: “Fast-growing species are considered as those capable of a mean annual increment of at least 10 cubic meters per hectare”. Nel frattempo, da qua…
Dead wood profile of a semi-natural boreal forest – implications for sampling
2019
Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead wood, and on the effect of sampling intensity on the dead wood estimates. In a semi-natural boreal forest, we measured every dead wood item over 2 cm in diameter from 80 study plots. From eight plots, we further recorded dead wood items below 2 cm in diameter. Based on these data we constructed the full dead wood profile, i.e. the overall number of dead wood items and their distribution among different tree species, volumes of different size and decay stage categories. We …
Survival, Growth and Mycorrhization of Containerised Pinus sylvestris and Picea abies Seedlings of Different Provenances Outplanted in a Forest Clear…
2017
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…
Low mimosine content and nutrient-rich foliage of two Leucaena leucocephala varieties: a potential fodder resource in Mediterranean agroforestry syst…
2022
Leucaena leucocephala is worldwide used for wood production, reforestation and for feeding livestock. To assess the potential use of leucaena for animal nutrition, we analysed the composition of methanolic extracts of leaf samples of two varieties occurring in Sicily (Mediterranean area), also determining the presence of mimosine.
