Black locust (Robinia pseudoacacia L.) is indigenous to eastern and central U.S.A. The species was introduced to Europe by Robin in the early seventeenth century. At present, the area of black locust forests is about 300,000 ha in Hungary, the largest in Europe.
From a utilization standpoint, wood of black locust is of great importance due to its outstanding durability, high physical and mechanical properties, and aesthetically pleasing grain. Wood quality of black locust in connection to its growing condition was investigated. Results of investigation on the characteristics of the structure and physical and mechanical behavior of black locust wood will be presented together with the effects of hydrothermal treatment on wood properties. Based on research experience of fifteen years, a short review of the suitability of black locust for different purposes will be discussed with special emphasis on its drying and machining properties.
Key words: Robinia pseudoacacia L., wood properties, hydrothermal treatment, wood utilization.
