effects of plant roots on increasing soil shear strength depend on root tensile strength. thus, determination of root tensile strength can provide the necessary data for analyzing root-soil relations. tensile strength of plant roots varied in a wide range and have been reported from thousands to millions of mpa. the main objective of this study was to assess inter-species variations of root ten...
The main purpose of this study is to investigate the quantitative and qualitative characteristics of dominant tree species and their regeneration status in the Arasbaran forests. Data were collected by transect sampling and regeneration was assessed by plot with an area 100 m2. In the sample plots, we recorded information on species type, diameter at breast height, height, quality of seedlings ...

European hornbeam (Carpinus betulus L.) is a tree species widely distributed in Europe and the Asian part of Near East. However, since not very attractive for commercial purposes, scientific interest this has been rather sparse. Our study focused on dense young (up to 10 years old) stands originating from natural regeneration seeds Slovakia because future importance may increase due climate cha...
