Resumo(s)
The importance of the establishment of short-rotation tree plantations for fuel
production has been of international interest for many years. In this context, in Hungary, these
plantations have been conducted for a long time. In this country, the black locust (Robinia
pseudoacacia L.) is one of the most important stand-forming tree species, covering
approximately 23% of the forested land (410 000 ha) and providing about 19% of the annual
timber output. This paper describes an experimental energy plantation that was established in
Helvécia (Central-Hungary, sand-soil region) using common black locust and its improved
cultivars. The site may be considered as representative of an average yield class for black locust
in Hungary. The experimental plantation was established with a spacing of 1.5 m x 1.0 m and
included common black locust and two cultivars, 'Üllői' and 'Jászkiséri, as well as a plot
regenerated by coppice. At the age of 7, the highest annual increment in stem oven-dry mass
was produced by the cultivar 'Üllői' (9.7 Mg ha-1 yr-1) followed by the common black locust (8.4
Mg ha-1 yr-1) and the cultivar 'Jászkiséri (7.6 Mg ha-1 yr-1). In the plot of coppice origin,
dendromass ranged from 6 to 8 Mg ha-1 yr-1 on an average.
