Sorbus Aria

A comprehensive checklist of the Tuscan woody flora providing sub-regional details is presented. This checklist comprises 412 taxa, of which 264 are native and 148 are non-native. Nine taxa new for the region were found, and eleven taxa were excluded from the regional flora. The native taxa belong to 109 genera and 53 families. Rosaceae is the family richest in taxa, with Rosa being the genus with the highest number of species. On the provincial level, the province of Grosseto is the province with the highest number of native taxa, followed by the provinces of Lucca and Florence. The lowest number of taxa was documented in the provinces of Pistoia and Prato. With regard to the non-native woody flora, the highest number of non-native taxa can be found in the province of Livorno, whereas the lowest number occurs in the provinces of Arezzo and Siena. At regional level, 9% of non-native taxa are invasive, 45% naturalized and 46% casual. Asia and North America are the most common native ranges of those taxa. After an extensive herbarium study, the taxonomy and distribution of Acer opalus, Cornus sanguinea, Juniperus deltoides, Oreoherzogia alpina, Pyrus communis, Quercus crenata, Salix elaeagnos, and Sorbus aria are discussed in more detail.

Sorbus Aria

Abstract In the southern Julian Alps we described two communities whose tree layer is dominated by species from the genus Sorbus and noted two successional stages in the overgrowing of abandoned agricultural land (pastures, hay meadows). In the secondary succession on former subalpine pastures above the alp Planina Razor und under the Breginjski Stol ridge, where potential natural vegetation consists of subalpine beech forest, dwarf pine has been overgrown with mountain ash (Sorbus aucuparia) whose stands are classified into the new association Rhododendro hirsuti-Sorbetum aucupariae. Whitebeam (Sorbus aria) has established itself on steep former hay meadows in the belt of altimontane beech forests under Mts. Jalovnik and Krikov Vrh, on gullied slopes on mixed geological bedrock dominated by chert, and these stands are classified into the association Calamagrostio arundinaceae-Sorbetum ariae. While occupying only small areas these two pioneer stages, as the sites of some rare or protected species, are nevertheless important biotopes and play a vital role in protection against avalanches.

Sorbus Aria

Five Sorbus L. species of different ecological and geographical origin growing in the VNIISPK arboretum were studied. The Institute is located 368 km southwest of Moscow, on the Central Russian upland in the European part of Russia. The studies were carried out in 2014–2016. The reaction of different Sorbus L. species to a three-day thaw +2°C with a subsequent decrease in temperature to –25°C in February and –30°C in March was studied in order to identify adapted species to the climatic conditions of the Orel region for use in ornamental horticulture. As a result of the experiment, we recommend Sorbus aria (L.) Crantz, Sorbus aucuparia L. and Sorbus alnifolia (Siebold. et Zucc.) K. Koch. as adapted species for the Orel region to create sustainable landscape compositions.
