Graft Propagation of Walnut (Juglans Regia L.) Under High Plastic Tunnel in Van Ecological Conditions
Abstract
Bu çalışma, Van ekolojik koşullarında cevizin (Juglans regia L.) örtü altında aşıyla çoğaltılma imkanlarının araştırılması amacıyla 2006-2007 yıllarında yapılmıştır. Aşı kalemleri 2006 yılı Mart ayında ceviz üretici bahçelerinden toplanmış, Mart 2006'da yedi farklı tarihte dilcikli aşı yöntemiyle aşılanmıştır. Vejetasyon periyodu sonunda, ceviz aşılarında canlı kalma yüzdeleri % 85.1 ile %98.7 arasında değişmiştir. Canlı kalma yüzdeleri aşılama tarihlerine göre istatistiki olarak farklılık göstermiştir (P<0.05). Diğer yandan, ilk vejetasyon gelişme periyodunun ardından aşılı ceviz bitkileri, şiddetli kış soğuklarından korumak amacıyla, iki farklı ortama (yüksek plastik tünel ve yüksek plastik tünel içinde alçak plastik tünel) bırakılmıştır. Kış sonrasında Nisan sonunda (2007), yüksek plastik tünel ortamında tutulan aşılı cevizlerde % 91.2, yüksek plastik tünel içinde alçak plastik tünel ortamında tutulan aşılı cevizlerde ise % 96.8 canlı kalma oranı tespit edilmiştir. Araştırma, Van ekolojik şartlarında ceviz aşılarında örtü altı ortamları kullanılarak yüksek canlı kalma yüzdeleriyle sonuçlanmıştır.
The study was performed in order to determine the possibilities of the graft propagation of walnut (Juglans regia L.) under high plastic tunnel (protected cultivation) in Van ecological conditions during 2006-2007. The scions were collected from walnut producer gardens in mid-March 2006, and they were grafted onto two years old walnut seedlings in seven different dates in March 2006 using tongue-graft technique. At the end of the vegetation period, the mean survival percentage for grafted walnut plants were recorded from 85.1 % to 98.7 %. The survival percentages differed by the grafting dates statistically (P<0.05). On the other hand, the grafted walnut plants were placed into two different mediums (high plastic tunnel and low plastic tunnel within high plastic tunnel) before winter to protect from severe winter freezes following the first vegetation growing period. After winter, the mean survival percentages recorded in late April 2007 were 91.2 % in high plastic tunnel and 96.8 % low plastic tunnel within high plastic tunnel. Findings revealed successful results in obtaining high graft survival percentages in Van ecological conditions, and in protecting the grafted walnut plants from winter freezes using protected cultivation.
