Bu çalışmada, yetiştirme sıklığı ve gübrelemenin boylu ardıç (Juniperus excelsa Bieb.) fidanlarının morfolojik özellikleri üzerine etkileri araştırılmıştır. Bu amaçla, dört farklı sıklık derecesi [metrekarede 150, 250, 350 ve 600 (=kontrol) fidan] ve üç farklı gübre dozu [metrekareye 0 g N (=kontrol), 10 g N ve 20 g N] denemeye alınmıştır. Bu bağlamda, uygulanan işlemlerin önemli fidan morfolojik özelliklerinden olan fidan boyu, kök boğazı çapı, yan dal sayısı, en uzun yan kök boyu ve gövde/kök kuru ağırlık oranı üzerine olan etkileri incelenmiştir. Denemeye alınan işlemler sonucunda elde edilen veriler SPSS paket programında değerlendirilmiştir. Buna göre; fidanların kök boğazı çapı üzerine etkili olan temel faktörün yetiştirme sıklığı olduğu ortaya çıkmıştır. Aynı şekilde, fidan boyu üzerine etkili olan temel faktörün ise gübreleme dozu olduğu tespit edilmiştir. Sonuç olarak; Eğirdir Orman Fidanlığında yürütülen boylu ardıç fidanı yetiştirme çalışmalarının, metrekarede 150-350 fidan olacak şekilde yapılması ve metrekareye 10 g N verilmesi uygun olacaktır.

In this study, the effects of growing density and fertilization on the morphological characteristics of the Crimean Juniper (Juniperus excelsa Bieb.) seedlings were investigated. For this purpose, four different growing densities [150, 250, 350 and 600 (= control) seedlings per square meter] and three different fertilizer doses [0 g N (= control), 10 g N and 20 g N per square meter] were studied. In this context, the effects of the treatments on the height (SH), root collar diameter (RCD), number of sub branches (NSB), the longest lateral root length (LRL) and shoot:root ratio (S:R) of the seedlings, which are among the important morphological characteristics, were examined. The data were evaluated in SPSS software. Results showed that the main factor affecting the root collar diameter of the seedlings was growing density. Similarly, it was found that the main factor working on the seedling height was fertilization dose. As a conclusion; it was suggested that cultivation of barerooted Crimean Juniper seedlings in the Eğirdir Forestry Nursery should be carried out with 150-350 seedlings per square meter and 10 g/m2 N application.
