Özet
Bu araştırmada, 'Rubygem' çilek çeşidinin (Fragaria × ananassa Duch.) tuz stresine verdiği morfolojik, fizyolojik ve biyokimyasal tepkiler ile bazı yeni nesil gübrelerin bu stres üzerindeki etkileri değerlendirilmiştir. Deneme, Malatya Turgut Özal Üniversitesi Ziraat Fakültesi serasında kontrollü koşullarda yürütülmüş, 35 mM NaCl ile oluşturulan tuz stresine karşı yeni nesil gübrelerinin etkinliği araştırılmıştır. Elde edilen sonuçlar, tuz stresinin bitki gelişimini, fotosentez performansını, pigment içeriğini olumsuz etkilediğini ve membran geçirgenliği, lipit peroksidasyonu (MDA), antioksidan enzim (SOD, POD) aktiviteleri ile prolin birikimini arttırdığını ortaya koymuştur. Yeni nesil gübre uygulamaları, morfolojik büyüme (taç ve kök ağırlığı, yaprak alanı), fizyolojik parametreler (stomal iletkenlik, yaprak su içeriği, fotosentez hızı) ve biyokimyasal özelliklerde (antioksidan savunma, pigment içeriği) önemli iyileşmeler sağlayarak tuz stresinin olumsuz etkilerini azaltmada etkili olduğu belirlenmiştir. Bu çalışmanın bulguları, biostimulant içerikli yeni nesil gübrelerin, çilek yetiştiriciliğinde tuzluluk stresine karşı sürdürülebilir üretim için önemli bir alternatif olduğunu ve gelecekteki çalışmalarda bu gübrelerin farklı bitki türleri ve tarım koşullarında test edilmesinin yararlı olacağını göstermektedir. Bu çalışma, Malatya Turgut Özal Üniversitesi Bilimsel Araştırma Projeleri Koordinasyon Birimi tarafından 24Y08 numaralı proje kapsamında desteklenmiştir.

In this study, the morphological, physiological, and biochemical responses of the 'Rubygem' strawberry variety (Fragaria × ananassa Duch.) to salt stress and the effects of some new-generation fertilizers on this stress were evaluated. The experiment was conducted under controlled conditions in the greenhouse of the Faculty of Agriculture at Malatya Turgut Özal University, and the effectiveness of new generation fertilizers against salt stress created with 35 mM NaCl was investigated. The results revealed that salt stress negatively affected plant growth, photosynthetic performance, and pigment content, and increased membrane permeability, lipid peroxidation (MDA), antioxidant enzyme (SOD, POD) activities, and proline accumulation. The application of new generation fertilizers was found to be effective in reducing the negative effects of salt stress by providing significant improvements in morphological growth (crown and root weight, leaf area), physiological parameters (stomatal conductance, leaf water content, photosynthesis rate), and biochemical characteristics (antioxidant defense, pigment content). The findings of this study indicate that new generation fertilizers containing biostimulants are an important alternative for sustainable production against salinity stress in strawberry cultivation and that testing these fertilizers on different plant species and under different agricultural conditions in future studies would be beneficial. This study was supported by the Scientific Research Projects Coordination Unit of Malatya Turgut Özal University under project number 24Y08. KEYWORDS: Strawberry, Salt Stress, New-Generation Fertilizer, Antioxidant Enzymes, Proline, MDA
