Abstract

Two year-old nursery stocks of Anatolian black pine (Pinus nigra Arnold subsp. pallasiana (Lamb.) Holmboe) from nine provenances were examined for morphological properties such as height, root collar diameter, sturdiness and shoot: root ratio. The stocks were grown in the Eskiflehir, E¤irdir and Seydiflehir forest nurseries in semi-arid sites in Turkey. It was found that all of the seedlings grown in E¤irdir were substandard but, the ones grown in Eskiflehir and Seydiflehir met the criteria of the Turkish Standards Institute (TS 2265 / February 1988). According to the seedling quality criteria of the Eurepean Community (EC), while all of the nursery stocks from E¤irdir were substandard eightly-three per cent of samples from Seydiflehir and eighteen per cent from Eskiflehir were quality seedlings. Anatolian black pine stocks should be graded into three root-collar diameter classes; and seedlings less than 5.0 cm in height and 3.0 mm in diameter should not be used in plantations. The Turkish Forest Tree Seedling Standards should be revised without delay, taking the standards of the EC into consideration.

Özet

Bu çalışmada Eskişehir, Eğirdir ve Seydişehir Orman Fidanlıklarında yetiştirilen 9 farklı oriwinden 2+0 yaşındaki Anadolu Karaçamı (Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe) fidanlarının fidan boyu, kök boğazı çapı, fidan boyu-kök boğazı çapı oranı ve gövde-kök oranı gibi kalite özellikleri incelenmiştir. Eskişehir ve Seydişehir Fidanlıklarında üretilen fidanlar, mevcut Türk Standartlarına (TS 2265/fiubat 1988) uygundur. Eğirdirde üretilen fidanların ise, tamamı ıskarta fidandır. Avrupa Birliği için hazırlanan standartlara göre, Eğirdirde üretilen fidanların hemen tamamı ıskarta fidan iken, Eskişehirde üretilenlerin sadece % 18i, Seydişehirde üretilenlerin % 83ü kalitelidir. Karaçam fidanlarının, kök boğazı çapına göre üç kalite sınıfına ayrılması daha uygun olacaktır. Boyu 5.0 cmden, kök boğazı çapı 3.0 mmden küçük fidanlar dikimlerde kullanılmamalıdır. Türk Orman Ağacı Fidanı Standartları, Avrupa Birliği Standartları dikkate alınarak yeniden revize edilmelidir.
