Yield table for selected black locust (Robinia pseudoacacia L.) cultivars

In Hungary, the black locust (Robinia pseudoacacia L.) can be considered as most important fast-growing, stand-forming introduced tree species. Due to its positive growing technological characteristics well wood utilization possibilities, at present, is widely planted species in covering 25% of country’s total forest area. One tasks ahead Hungarian growers improve quality stands with introducing selected cultivars. For estimation growth rate and yield a numerical table has been constructed on basis surveys experimental plots established pure,managed ’Nyirségi’ ,’Üll?i’ ’Jászkiséri’ cultivars’ plantations which suitable for sawlogs production. course 56 stand key were measured, then, reconsidered average height, diameter (DBH), volume, basal area stem number given separately main (remaining), secondary (removal) per hectare. The programmable editing procedure allows extention formal change information content according different demands.
