Abstract:

 This study was carried out to determine the effect of different doses of salicylic acid SA and sodium chloride NaCl treatments on seed germination and seedling development in Olympus cultivar of tall fescue Festuca arundinacea. The study was conducted in the laboratory of Ordu University, Faculty of Agriculture with 5 replications according to the factorial experiment design in randomized plots. Salicylic acid was applied at 0, 0.25, 0.50, 0.75 and 1.0 mM and NaCl was applied at 0, 50, 100, 150, 200, 250 and 300 mM doses. As a result of the analysis of variance, the SAxNaCl interaction was found to be statistically significant only in terms of germination rate and mean germination time. While increasing salt stress reduced the germination rate, the effect of salicylic acid under the same salt stress conditions was positive or negative depending on the dose. The germination rate was over 60  in all treatments up to 250 mM salt dose. But in all treatments with salt doses of 150 mM and above, seedling development was severely suppressed. For this reason, it was determined that Olympus variety could not tolerate NaCl stress above 100 mM during the germination period and salicylic acid did not have a tolerance-increasing effect. When germination and seedling development were evaluated together, it was specified that 0.75 mM salicylic acid pre-application had positive effects under 50 mM NaCl stress conditions.

 Araştırma, farklı dozlarda salisilik asit SA ve sodyum klorür NaCl uygulamalarının kamışsı yumağın Festuca arundinacea Olympus çeşidinde tohum çimlenmesi ve fide gelişimine etkisini belirlemek amacıyla yapılmıştır. Çalışma, Ordu Üniversitesi Ziraat Fakültesi laboratuvarında, tesadüf parsellerinde faktöriyel deneme desenine göre 5 tekrarlamalı olarak yürütülmüştür. Çalışmada SA 0, 0.25, 0.50, 0.75 ve 1.0 mM, NaCl ise 0, 50, 100, 150, 200, 250 ve 300 mM dozlarında uygulanmıştır. Yapılan varyans analizi sonucunda, sadece çimlenme oranı ve ortalama çimlenme süresi bakımından SAxNaCl interaksiyonu istatistiki olarak önemli bulunmuştur. Tuz stresinin artması çimlenme oranını azaltırken, aynı tuz stresi şartlarında salisilik asidin etkisi doza bağlı olarak olumlu veya olumsuz olmuştur. Çalışmada 250 mM tuz dozuna kadar olan bütün işlemlerde çimlenme oranı  60ın üzerinde gerçekleşmiştir. Ancak 150 mM ve üzeri tuz dozlarındaki bütün işlemlerde ise fide gelişimi çok şiddetli bir şekilde baskılanmıştır. Bu nedenle Olympus çeşidinin çimlenme döneminde 100 mMın üzerindeki NaCl stresine tolerans gösteremediği ve salisilik asidin toleransı artırıcı etkisinin olmadığı belirlenmiştir. Çimlenme ve fide gelişimi birlikte değerlendirildiğinde ise 50 mM NaCl stresi şartlarında 0.75 mM salisilik asit ön uygulamasının olumlu etkilerinin olduğu tespit edilmiştir.
