Abstract
The paper analyses the stand structure and yield of black locust (Robinia pseudoacacia) stands mixed with grey poplar (Populus × canescens) in various proportions, partly applying a new methodological approach. The main stand structure and yield factors were determined separately for each species, measured stem by stem, using the volume functions prepared for each species. The ratio of the volumes of the species (RVA and RVB) was determined based on the particular yield tables. A close relationship has been found between the ratio of relative volume and the proportion of the species calculated by number of stems. The relative surplus in the volume of the mixed stands varied between l.32-1.80 at age 16 and 21 years compared to the control, i.e. the yield of pure stands of the species concerned. The investigations have also proven that if two species have a fast initial growth rate and a similar rotation age, they can be planted in mixed stands resulting in mutual growing advantages.
