According to the statistical analysis results, the site characteristics (slope, aspect, altitude, parent material) and soil properties (stored sand and clay, topsoil (solum) depth and organic carbon content) were effective on diameter and height growth performance of Quercus brantii L. (Persian oak) and Q. cerris L. (Turkey oak) species which were directly sown to the soil in Elâzığ province.

Abstract

To reveal the relationship between growth performance of oak seedlings planted for the soil conservation in Elâzığ province, in 1999, and some site characteristics the research was established. Fifty-four sample plots, which were 20x20 m size, were determined homogeneously according to different altitude, aspect, slope degree and slope position. Identification of oak species of all individuals was made in these sample plots, and two individuals were cut at the root collar to confirm that they were at an even age. Height and root collar diameter measurements of the tree species were carried out in 51 sample plots, disturbed and undisturbed soil samples were taken from soil profiles from different depths. In three plots where oak seedlings could not survive, only soil samples were taken to determine whether the failure was related to the soil characteristics. The collected data were analyzed by the classification and regression tree technique with DTREG software. According to the statistical analysis results, the site characteristics (slope, aspect, altitude, parent material) and soil properties (stored sand and clay, topsoil (solum) depth and organic carbon content) were effective on diameter and height growth performance of Quercus brantii L. (Persian oak) and Q. cerris L. (Turkey oak) species which were directly sown to the soil in Elâzığ province.

Özet

Elâzığ ve çevresinde, 1998 yılında toprak muhafaza amacı ile yapılan meşe ekimlerinin gelişimi ile bazı yetişme ortamı özellikleri arasındaki ilişkinin açığa çıkarılması amaçlanmıştır. Bunun için farklı yükselti, bakı, eğim ve yamaç konumuna göre dağılımları homojen yapılmış 20x20 m ebadında 54 adet örnekleme alanı belirlenmiştir. Bu örnekleme alanlarında tüm fertlerin tür teşhisleri yapılmış ve aynı yaşlı olduklarını teyit etmek için her örnekleme alanında iki fert dipten kesilmiştir. 51 adet örnek alanında türlerin boy ve dip çap ölçümleri yapılmış, açılan toprak profillerinden derinlik kademesine göre bozulmuş ve bozulmamış toprak örnekleri alınmıştır. Meşe ekimi yapılmış ancak başarısız olunmuş üç adet örnek alanda ise başarısızlığın toprak özellikleri ile ilişkili olup olmadığını tespit etmek amacıyla sadece toprak örnekleri alınmıştır. Elde edilen veriler sınıflandırma ve regresyon ağacı yöntemi (STRAT) ile analiz edilmiştir. Modelleme DTREG programı kullanılarak gerçekleştirilmiştir. İstatistik analiz sonuçlarına göre, Elâzığ ve çevresinde ekimle yetiştirilen Quercus brantii L. (İran palamut meşesi) ve Quercus cerris L. (saçlı meşe) türlerinin çap artımı ve boy büyüme performansı üzerinde, yetişme ortamı özellikleri (Eğim, bakı, rakım, anakaya) ve toprak özellikleri (rezerve kum, kil ve organik karbon içeriği, mutlak toprak derinliği) etkili olmuştur.
