Abstract

In this study, in order to investigate REGENERATION success and determine the best GAP area, the quantitative characteristics of the REGENERATION groups were evaluated at different GAP area classes. For this purpose, 15 REGENERATION GAPs were selected at three area classes with five replications at each class, including: 50-150 (small), 150-300 (medium) and 300-600 m2 (large). Four square meter plots at two meter intervals were used to measure some quantitative characteristics of the REGENERATION groups by a simple systematic design on north-south (N-S) and east-west (E-W) transects. The data was analyzed, using the completely randomized statistical design and one way variance analysis and Duncan test methods. The Results showed that the total height and the height growth of the SAPLINGs were significantly higher in the large GAPs in comparison to the small GAPs. In addition, the frequency of seedlings and the density of SAPLING were the greatest in the medium sized GAPs. For this reason seedling frequency of CARPINUS betulus and Parrotia persicawas found in the medium sized GAPs. Overall, it can be concluded that in the selection cutting method, the medium sized GAPs (150-300 m2) are the most suitable ones.
