Growing of Black Locust (Robinia pseudoacacia L.) Candidate Cultivars on Arid Sandy Site

In the late 1990s, Hungarian Forest Research Institute researchers produced 15 micropropogated black locust (Robinia pseudoacacia L.) clones as part of a program to select that could be successfully grown on arid sites. Five these (R.p. ‘Vacsi’, R.p. ‘Szálas’, ‘Oszlopos’, ‘Homoki’ and ‘Bácska’) have been categorized cultivar candidates. The current study presents information concerning ‘Bácska’, ‘Vacsi’ candidate cultivars. Based research results obtained thus far, three aforementioned cultivars seem most promising. cultivars, aged 6-15 years, were tested in variety comparison trial under arid, sandy soil conditions Danube–Tisza Interfluve near town Helvécia. Significant differences (p<0.05) observed during evaluation full inventories partly with common ‘Jászkiséri’ 15-yearold outperformed diameter mean tree volume; stem quality. 14-year-old ‘Bácska’ was compared ‘Oszlopos’ candidate. proved significantly better volume than Jászkiséri’, but weaker trunk South Korean National Science has supported this for several years. growing technology mentioned are also examined Korea, taking local ecological into account.
