Abstract

Bu çalışma, Elazığ Orman İşletme Müdürlüğü, Altınova Orman İşletme şefliğine ait Orman Fidanlığında yetiştirilen Siirt-Pervari orjinli cevizlerde (Juglans regia L.) gerçekleştirilmiştir. Çalışmada ekim yastıklarına ekilen ve çimlenen tohumlarda radikula ve yerinde kök kesimi uygulamaları yapılarak fidan kalite özelliklerinden; fidan boyu (FB), kök boğazı çapı (KBÇ), ana (AKS) ve yan kök sayıları (YKS) ile gürbüzlük indeksi (Gİ) üzerinde bu uygulamaların etkilerinin belirlenmesi amaçlanmıştır. Varyans analizi sonuçlarına göre; yerinde kök kesimi ve radikula kesimi yapılan fidanlar arasında FB, Gİ ve AKS bakımından istatistiki anlamda (α=0.001) farklılıklar bulunmazken, kontrol grubundaki fidanlar, daha uzun boy büyümesi yaparak istatistiksel olarak farklı bulunmuştur. Fidanların KBÇ ve YKS açısından radikula kesimi, yerinde kök kesimi ve kontrol grubu arasında istatistiki açıdan anlamlı (α=0.001) farklılık bulunmamıştır. Fidanların anakök sayıları ise radikula ve yerinde kök kesimi yapılan gruplarda kontrol grubuna göre istatistiksel anlamda önemli ve 3 kat daha fazla bulunmuştur.

Effects of Radicle Pruning and Under Cutting on Seedling Quality Characteristics of Walnut (Juglans regia) Seedings Collected From Siirt-Pervari

Abstract

This study was carried out with Siirt-Pervari originated seedlings in Altınova forest state nursery of Elazığ Forest management directorate. The purpose of the study were to determine the effects of radicle pruning and under cutting on the seedlings at seedbeds in terms of seedling height, root collar diameter, primary and secondary root numbers and grade characteristics. According to the results of variance analysis; there was not any statistically significant difference (α=0.001) between the application of under cutting and radicle pruning treatments in terms of seedling height, grade characteristics and primary root numbers. On the other hand, seedlings in the control group had higher shoot height growth. Moreover, there was not any significant difference (α=0.001) about seedling shoot height growth and secondary root numbers among the application of under cutting, radicle pruning and control. Besides, the numbers of primary roots in the applications of radicle pruning and under cutting were statistically significant and 3 times higher than control group.
