Through the determination of the volume in sections along the stem, the stem form, the stem volume and other factors can be specified. The comparison of the stems of individual trees of first and third yield classes of black locust (Robinia pseudoacacia L.) stands shows that site conditions have a main effect on the yield (mean tree volume). The difference can be as high as 53% at the age of 30 depending on the sites. To determine the growth patterns based on tree volume is rather a new approach in the light of the relevant literature. The obtained results also highlight the importance of choosing the appropriate tree species for a given site.Tétel Szabadon hozzáférhető Simplified volume equations for grey poplar (Populus × canescens Smith.) standing trees(2024-06-03) Ábri, Tamás; Honfy, Veronika; Rédei, KárolyGrey poplar (Populus× canescens Smith.) is a natural hybrid of white poplar (Populus alba L.) and Eurasian aspen (Populus tremula L.). It can be found throughout Europe, where both parents are present. The above mentioned species of poplars (under the term of ‘domestic poplars’) cover approximately 5% of the forests of Hungary. Of these species, grey poplar holds significance in forestry, and its role in afforestation shows a growing tendency. For this reason, improving the growing technology of grey poplar is a timely topic. In this paper we introduce algorithms which help estimate grey poplar tree volumes without having to use volume tables. Based on the performed evaluations, both equations can be used for single tree volume estimation with an error of less than 5%.Tétel Szabadon hozzáférhető The effect of tree spacing on yields of Alley Cropping Systems: A case study from Hungary(2023) Honfy, Veronika; Pödör, Zoltán; Keserű, Zsolt; Rásó, János; Ábri, Tamás; Borovics, Attila
