In Hungary the black locust (Robinia pseudoacacia Linnaeus) is one of the most important exotic stand-forming tree species growing mostly under unfavourable ecological conditions. Considering the climate change effects its importance is increasing also in many other countries. As a result of a selection programme several black locust cultivars have been improved for setting up cultivar trials. In the paper four black locust cultivars were evaluated in Central Hungary under arid hydrological and brown forest soil conditions. Significant differences (P < 5%) were found in height, DBH, mean tree volume and average stem form value (SFV). At the age of 35 years the cultivar “R.p. Jászkiséri” appeared to be the most promising one for yield production and “R.p. Zalai” and “R.p. Nyírségi” for SFV.

In Hungary, black locust (Robinia pseudoacacia L.) is considered as an important exotic stand-forming tree species growing mostly under unfavourable ecological conditions for forest management. Due to climate change effects, its importance is increasing in many other countries, too. As a result of a selection programme, new black locust clones were tested in clone trials. Juvenile growth of 12 micropropagated black locust clones in two plots series established at different dates were evaluated in central Hungary under marginal site conditions. At age of 7 the clone R. p. ‘Bácska’ (‘KH 56A2/5’), at age of 10 the clones R.p. ‘Homoki’ (‘MB17D3/4’) and ‘PV201E2/4’ appeared to be especially promising for mass production. Based on the data obtained from the performed trials, it can also be concluded that tissue culture can be considered as a suitable tool for propagating superior individuals and offers new prospects for the rapid cloning of selected genotypes used for plantation forestry.

In Hungary black locust (Robinia pseudoacacia L.) is considered as an important exotic stand-forming tree species and due to climate change effects its importance is increasing in many other countries. It has some desirable characteristics from both the practical and research standpoints. As a result of a partly new black locust selection programme new black locust clones were improved and a technology was developed for mass clonal micropropagation of juvenile trees. Clone trials with micropropagated plants were established in the country for evaluating the juvenile growth and the stem form of promising black locust clones under marginal site conditions. Significant differences (P<5%) were found for stem form value which partly verified the genetic gain of the selected clones against the common black locust. It was also proved that tissue culture could offer partly new prospects for the rapid mass cloning of selected genotypes.

Abstract - In Hungary black locust (Robinia pseudoacacia L.) is considered as an important exotic stand-forming tree species growing mostly under unfavourable ecological conditions for forest management. Due to climate change effects its importance is increasing in many other countries, too. As a result of a selection programme new black locust clones were tested in clone trials. Juvenile growth and the morphological as well as phenological traits of four micropropagated black locust clones were evaluated in central Hungary under dry site conditions. Significant differences (P<5%) were found for DBH and field survival rate values. At age of 7 the clone R.p. ‘Bácska’ (’KH 56A 2/5’) appears to be especially promising for mass propagation. Tissue culture can be considered as a suitable tool for propagating superior individuals and offers new prospects for the rapid cloning of selected genotypes used for plantation forestry.

Black locust (Robinia pseudoacacia L.) is the most important fast growing stand-forming tree species in Hungary. Its importance is increasing in many other countries, too. As a result of a new selection programme 13 black locust clones have been improved for setting up clones trials and seed orchard. In 2003 five of them (R.p. `Bácska', `Homoki', 'Szálas', `Oszlopos' and `Vacsi') were registered as cultivar­candidates. Tissue culture method has proved as a suitable mean of propagating superior individuals. The micropropagated plants have been growing successfully in the clone trials.

The Town

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

Variability within R. pseudoacacia species represents an important factor in selection of fast-growing genotypes. Therefore, it is important to identify superior individuals according to their anatomical and physiological traits. This paper presents the results of a study of genotype variability of the main leaf anatomical (frequency, length and width of stomata, leaflet thickness among veins, leaflet thickness on the main vein, mesophyll thickness, length and width of vascular bundle of main vein) and physiological (leaf area, photosynthetic pigments content and content of N P, K, Ca, Na) parameters among five clones of Robinia pseudoacacia L. Significant interclonal variations were observed in the investigated parameters. Clone R-56 had the highest N, P, and K concentrations, the largest mesophyll volume and the highest pigment concentration. We concluded that the clone R-56, although without a remarkable leaf area, possesses the ability for high photosynthetic production. The results are going to be used in further work on selection.

Robinia Pseudoacacia L

Black locust (Robinia pseudoacacia L.) is a valuable stand-forming tree species introduced to Europe approximately 400 years ago from North America. Today it is widely planted throughout the world, first of all for wood production. In Hungary, where black locust has great importance in the forest management, it is mainly propagated by seeds. But since the seed-raised plants present a great genetic variation, this type of propagation can not be used for Robinia’s improved cultivars. In the Hungarian black locust clonal forestry, propagation from root cuttings can be used for reproduction of superior individuals or cultivars in large quantities. However, this method demands more care than raising seedlings from seeds and can be applied with success in well-equipped nurseries.
