two-row linear plantation of cl. I-214 at age 10 years, Marković and Živanov (1980) recorded diameters of 30–40 cm, heights of 20–25 m and volume of 519 m3∙ha−1. The Italian alder trees in the plantation have monopodial growth, conical bole axis and low-hanging branches due to weak competition for growing space. Slenderness coefficient, as the bole form indicator (Pretzsch 2009), decreases with trees age. At age 11 years, slenderness coefficient was 54 on average and 43 at age 16 years. Italian alder has fragile wood so tip breakages were recorded on some of the trees that quickly regenerated. If high density plantations are to be established, and thinnings prescribed, optimal spacing as well as the possibility of mixed species plantations should be investigated first, as the species is prone to branching. In high density plantations, heavy and frequent thinnings are recommended because of the fast growth of Italian alder (Praciak et al., 2013). In the researched area, the maturation and pollen dispersal of male flowers of Italian alder occurs mostly at the end of January or the beginning of February, and is recorded on some of the trees at the end of December (Bobinac et al., 2015a). Italian alder is a nearly-flowering species, and in context of climate change could be important for beekeping in the area, together with common hazel (Corylus avellana L.), that is more widely grown in plantations. Despite the limits due to small sample and the fact that the linear plantation was analyzed, we generalise the following conclusion: the measured growth characteristics at age 11 and 16 years of Italian alder trees show that the species can grow fast and could be usable in Serbia — as a fast-growing tree species in plantations or as decorative in urban areas.
