The investigation of stand structure and juenility dynamics in natural regeneration areas of pure oriental beech (Fagus orientalis Lipsky.) in the Bartın-Kumluca region

In this thesis, the effects of size of regeneration area and some physiological factors on the success of natural regeneration in pure oriental beech stands in the Bartın-Kumluca region. In order to examine stand characteristics, youth development and rejuvenation success, measurements were made in the young generation in the old generation in 9 test areas in 19, 32 and 33 number sections, which were within the borders of Kumluca Forest Management Directorate and included in the natural rejuvenation program in 2016. On the seed trees that we consider as the mature generation; height measurements, diameter measurements and crown diameter measurements were carried out and the effects of seed trees on the success of natural regeneration were investigated. As a result of the measurements we made on seed trees; It was determined that the individuals selected as seed tree benefited from the yield power of the stand in the best way, the administration period came to an end and it was determined that the individuals holding the seeds in the crown and stem straightness contributed to the success of the regeneration studies. In the measurements made on height, root collar diameter, last year shoot length, leaf length and width natural of juvenilities; measurements were evaluated. As a result of these evaluations, it can be said that the juvenilities dynamics in the research area are in good condition.
