Effects of Pruning on Height and Diameter Growth at Stone Pine (Pinus pinea L.) Afforestations

Fıstıkçamı (Pinus pinea L.) Ağaçlandırmalarında Budama Uygulamasının Boy ve Çap Gelişimi Üzerine Etkileri

Abstract

In this study which was carried out in the stone pine afforestations in Bartın-Karaçaydere district, the effects ofpurning applications on height and diameter growth of stone pine trees at the end of the 5th year following thepurining were investigated. According to results obtained from measurements and determinations, it wasdetermined that there were significant differences between the pruned and control trees in terms of height anddiameter at P<0.05 and P<0.01 significance levels respectively. At the end of the 18th year, the mean height ofcontrol stone pine trees was 8,3 m and pruned trees was 10,5 m respectively. The mean diameter of control stonepine trees was 24,2 cm and pruned trees was 36,3 cm respectively. These results showed that pruningapplications had a positive effect on the height and diameter growth of stone pine.
