Stand structure and growth of Robinia pseudoacacia 'Jászkiséri' - 'Jászkiséri' black locust

Black locust (Robinia pseudoacacia L.) is one of the most widespread tree species introduced into Europe and also Hungary. It covers 24% total Hungarian forest area, providing 25% annual timber output country. Due to demands consumers, new cultivars are be produced by means improvement techniques practical forestry use. Mono- multiclonal were developed, then variety comparison trials cultivation tests established. Based on preliminary yield cultivar ‘Jászkiséri’ ‘Jászkiséri’) proved best black cultivars. Consequently, a more precise investigation stand structure this may make significant contribution relevant technology. In study, based full inventories 13 stands in 7 subcompartments, age 5 35 years, relationships mean volume diameter (R2 = 0.9797) basal area 0.9781), furthermore relationship between 0.9993) examined. Besides that, 15-year-old common (a case study) presented paper, where better: differences (P < 0.05) found diameter, stem form.
