    Improved clonal approaches to growing black locust (Robinia pseudoacacia L.) in Hungary: a case study
    (2015-04-12) Rédei, K.; Keserű, Zs.; Antal, B.
    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.

    Tending operation models for black locust (Robinia pseudoacacia L.) stands growing on sandy soils in Hungary
    (2015-09-20) Rédei, K.; Keserű, Zs.; Antal, B.
    A more intensive integrated research and development approach to the work carried out on the growth on sandy soils of stands of black locust (Robinia pseudoacacia L.) has been adopted in recent years, revealing several factors influencing stand growth. The fact that certain ecological factors influencing fundamentally the growth of trees have become unfavourable in Hungary in recent years has led to the more extensive use of black locust in the course of afforestation and forest regeneration schemes. The study presents a new,  simplified tending operation model for black locust stands and age, growing space and target diameter models suitable for qualitaty log production and for mass assortments. The simplicity of these practice-oriented models may foster the qualitative development of black locust management in Hungary and in some other countries where this tree species may gain greater acceptance by landowners and the forest industry.
