Mürdümükde biyokimyasal ve tarımsal tepkileri iyileştirmek için biyofiziksel uyarıcı olarak manyetik alan

Abstract

Bu çalışmanın amacı, ekim öncesi manyetik alan (MF) uygulamasının mürdümük fidelerinde antioksidan aktivite ve metabolit içeriğine etkisini belirlemek ve bitkinin büyümesi ve agronomik performansı üzerindeki etkisini değerlendirmektir. Mürdümük tohumları farklı manyetik alan yoğunlukları (0, 0.5, 0.7, 0.9 ve 1.1 Tesla) ile ön işleme tabi tutulmuş ve kontrollü koşullar altında yetiştirilmiştir. Fideler 28. günde hasat edilmiştir. Klorofil a, klorofil b, toplam klorofil, karotenoidler, MDA, prolin, toplam fenolikler, flavonoidler, tanenler, DPPH radikal süpürücü aktivitesi, ADF, NDF, ham protein ve makro besin maddeleri (Ca, K, Mg, P) dahil olmak üzere çeşitli fizyolojik ve biyokimyasal parametreler değerlendirilmiştir. Sonuçlar, manyetik alan uygulamalarının incelenen tüm parametreler üzerinde doza bağlı etkileri olduğunu ortaya koymuştur. En yüksek manyetik yoğunluk (1,1 T) klorofil içeriğini, protein seviyelerini, mineral birikimini ve enzimatik antioksidan aktivitelerini (SOD, CAT, APX) önemli ölçüde artırarak bitki gelişimini destekledi. Düşük yoğunluklu uygulamalar (özellikle 0 ve 0,5 T) daha yüksek derecede oksidatif stresi gösteren artan MDA ve prolin seviyeleriyle karakterize edildi. Orta yoğunluklu uygulamalar (özellikle 0,7 T) artan prolin ve fenolik bileşik birikimiyle ilişkilendirildi ve bu da stres adaptasyon mekanizmalarının aktivasyonunu önerdi. Genel olarak bulgular, özellikle 1,1 T gibi optimum dozlarda manyetik alan uygulamalarının bitki verimliliğini ve yem kalitesini iyileştirmek için çevre dostu ve sürdürülebilir bir tarımsal teknoloji aracı olarak hizmet edebileceğini göstermektedir.

Magnetic Field as Biophysical Elicitor for Improving Biochemical and Agronomic Responses in Grass Pea

Abstract

The aim of this study was to determine the effect of pre-sowing magnetic field (MF) application on antioxidant activity and metabolite content in grass pea seedlings, and to evaluate its impact on the plant’s growth and agronomic performance. Grass pea seeds were primed with different magnetic field intensities (0, 0.5, 0.7, 0.9, and 1.1 Tesla) and grown under controlled conditions. Seedlings were harvested on the 28th day. Various physiological and biochemical parameters were evaluated, including chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, MDA, proline, total phenolics, flavonoids, tannins, DPPH radical scavenging activity, ADF, NDF, crude protein, and macronutrients (Ca, K, Mg, P). The results revealed that magnetic field applications had dose-dependent effects on all examined parameters. The highest magnetic intensity (1.1 T) significantly enhanced chlorophyll content, protein levels, mineral accumulation, and enzymatic antioxidant activities (SOD, CAT, APX), thereby promoting plant development. Low-intensity applications (particularly 0 and 0.5 T) were characterized by increased MDA and proline levels, indicating a higher degree of oxidative stress. Moderate-intensity treatments (especially 0.7 T) were associated with increased proline and phenolic compound accumulation, suggesting the activation of stress adaptation mechanisms. Overall, the findings suggest that magnetic field applications,particularly at optimal doses such as 1.1 T, can serve as an eco-friendly and sustainable agrotechnological tool to improve plant productivity and forage quality.
