Özet:

 Background and aims Two of the most important factors that cause the vitality and vigor of seeds to decrease with aging are seed moisture and temperature. However, even if the seeds are stored at appropriate temperature and humidity, they age over time. Deterioration of cell membranes is another important hypothesis explaining aging in seeds and can be measured as increases in the electrical conductivity of substances leaking from the seed during aging. Biological-based coatings are mostly applied to seeds in the agricultural field and to foods in the food industry to extend their storage and shelf life. Chitosan, one of them, shows antioxidant activity by prolonging the post-harvest life of fruits and vegetables, promoting plant growth, quenching free radicals or binding metal ions. In addition, synthetic antioxidants such as butylated hydroxytoluene BHT and butylated hydroxyanisole BHA are frequently used to inhibit the formation of free radicals and prevent lipid auto-oxidation and food spoilage. Propolis, perceived as a natural antioxidant and antibacterial source, is very effective in extending the storage life of fruits and vegetables thanks to its antimicrobial, antifungal, antioxidative or antibacterial properties. Methods In this study, the effects of different coating applications on seed moisture and EC in delaying the time-dependent aging effects that occur during storage in oriental beech Fagus orientalis L. seeds, which are in the recalcitrant seed group, are investigated. In this context, pre-treated seeds were stored for 16 months. Results In the study, single, double and triple interactions of all factors had statistically significant effects on both moisture value and EC value in pre-treated and stored seeds. It was determined that all applications, especially after 4 months, significantly reduced the seed EC value and moisture content. Conclusions It is recommended to use chitosan as a coating material for short-term storage.

 Giriş ve Hedefler Tohumlarda yaşlanma ile birlikte canlılık ve gücün azalmasına neden olan en önemli faktörden ikisi tohum nemi ve sıcaklıktır. Bununla birlikte; tohumlar her ne kadar uygun sıcaklık ve nem koşullarında depolansalar da zamana bağlı olarak yaşlanmaktadırlar. Hücre membranlarının bozulması, tohumlarda yaşlanmayı açıklayan bir başka önemli hipotezdir ve yaşlanma esnasında tohumdan sızan maddelerin elektriksel iletkenliğinde EC meydana gelen artışlar olarak ölçülebilmektedir. Daha çok zirai tohumlarda ve gıda endüstrisinde gıdalarda depo ve raf ömrünü uzatmak için biyolojik tabanlı kaplamalar uygulanmaktadır. Bunlardan biri olan kitosan, meyve ve sebzelerin hasat sonrası ömrünü uzatmak, serbest radikalleri söndürerek veya metal iyonlarını bağlayarak antioksidan aktivite göstermektedir. Ayrıca, bütillenmiş hidroksitoluen BHT ve bütillenmiş hidroksianisol BHA gibi sentetik antioksidanlar, serbest radikallerin oluşumunu engellemek ve lipit oto-oksidasyonunu ve gıda bozulmasını önlemek için sıklıkla kullanılmaktadır. Doğal bir antioksidan ve anti-bakteriyel kaynak olarak olan propolis ise antimikrobiyal, antifungal, antioksidatif veya anti-bakteriyel özeliği ile meyve ve sebzelerin depo ömrünü uzatmada oldukça etkili olmaktadır. Yöntemler Bu çalışmada; Doğu kayını Fagus orientalis L. tohumlarında depolama boyunca meydana gelen zamana bağlı yaşlanma etkilerinin geciktirilmesinde farklı kaplama uygulamalarının kitosan, kitosanBHTBHA, kitosanpropolis tohum nemi ve EC üzerine etkisi araştırılmıştır. Bu kapsamda ön işlem yapılan tohumlar 16 ay boyunca depolanmıştır. Bulgular Çalışmada ön işlem yapılıp, depolanan tohumlarda bütün faktörlerin tekli, ikili ve üçlü etkileşimlerinin hem tohum nemi hem de EC üzerine istatistiksel olarak anlamlı etkileri tespit edilmiştir. İlk dört ay sonunda yapılan bütün uygulamaların tohum EC değerini ve nem içeriğini önemli ölçüde düşürmüştür. Sonuçlar Kısa süreli depolamada kaplama materyali olarak kitosan kullanımı önerilmektedir.
