Özet:

 It is extremely important to investigate the appropriate stand establishment for laurel, which is widely distributed along the entire coastline in our country. In this study, the effects of different stand establishments on laurel production were investigated in Bartın Forest Enterprise Directorate, where laurel production is intensive, and basic data on forestry practices were tried to be established. For this purpose, in order to reveal the stand structure in more detail, 20 m x 20 m 400 m2 sample plots were taken with the conscious sampling method in the sections where laurel is distributed. In the sampling area, important stand parameters such as stand canopy closure, layering, mixture ratio, mean diameter cm, mean height m, age and laurels number of stem per m2, number of shoots number, shoot length m, bottom diameter d0.30 number of dormant buds, number of leaves per m2, leaf width cm, leaf length cm were determined. Variance analysis, which was conducted for determining the changes in measured parameters in the laurel layer of the sample plots depending on stand closure and stand type, showed statistically significant p0.05 relationships in the number of patchs per square meter, average number of shoots, average number of dormant buds, average leaf width. According to the findings obtained from statistical analyses, it was determined that in the research area, laurel showed some superior qualities in terms of formation, development and leaf harvest in red pine and coastal pine plantation areas compared to natural eastern beech stands and this situation was due to the fact that the light conditions, especially in the bush layer where laurel is located in the plantation areas in question, have more suitable qualities than those for the development and yield potential of the species. As a result, by revealing the existing stand structures of laurel Laurus nobilis L., which is an important species in our country in terms of ecological, economic and social aspects, basic data for plans and silvicultural practices that will ensure its sustainable management were tried to be created.

 Ülkemizde tüm kıyı şeridi boyunca geniş bir yayılış gösteren defne için uygun meşcere kuruluşunun araştırılması son derece önemlidir. Bu çalışmada, defne üretiminin yoğun olarak yapıldığı Bartın Orman İşletme Şefliğinde, farklı meşcere kuruluşlarının defne üretimine etkisi araştırılarak ormancılık uygulamaları konusunda temel veriler oluşturulmaya çalışılmıştır. Bu amaçla meşcere yapısını daha detaylı ortaya koymak için defnenin yayılış gösterdiği bölmelerde bilinçli örnekleme yöntemiyle 20 m x 20 m 400 m2 büyüklüğünde örnek alanlar alınmıştır. Örnekleme alanında meşcereye ilişkin kapalılık, tabakalılık, karışım oranı, orta çap cm, orta boy m, yaş gibi önemli meşcere parametreleri ile defnelerin m2deki ocak sayısı, sürgün sayısı adet, sürgün boyu m, dip çapı d0.30 uyuyan göz sayısı, m2deki yaprak sayısı, yaprak eni cm, yaprak boyu cm özellikleri tespit edilmiştir. Örnekleme alanlarının defne katında yapılan ölçümlerle elde edilen verilerin ana meşcerenin kapalılığı ve meşcere tipine göre nasıl değişim gösterdiğinin belirlenmesi için yapılan varyans analizinde istatistiksel olarak anlamlı p0,05 ilişkiler bulunan parametrelerin metrekaredeki ocak sayısı, ortalama sürgün sayısı, ortalama uyuyan göz sayısı, ortalama yaprak eni olduğu belirlenmiştir. İstatistiki analizlerden elde edilen bulgulara göre araştırma alanında; defnenin oluşumu, gelişimi ve yaprak hasadı yönünden kızılçam ve sahilçamı plantasyon alanlarında, doğal doğu kayını meşcerlerine göre bazı üstün nitelikler gösterdiği ve bu durumundan söz konusu plantasyon alanlarında özellikle defne yer aldığı çalı katındaki ışık koşullarının türün gelişimi ve verim potansiyeli aşçısından daha uygun niteliklere sahip olmasından kaynaklandığı tespit edilmiştir. Sonuç olarak ülkemizde ekolojik, ekonomik ve sosyal açıdan önemli bir tür olan defnenin Laurus nobilis L. mevcut meşcere yapılarının ortaya çıkarılmasıyla, sürdürülebilir bir şekilde işletilmesini sağlayacak planlar ve silvikültürel uygulamalar için temel veriler oluşturulmaya çalışılmıştır.
