Temel amacı bilgi üreten, kullanan, eleştiren ve üretken bir düşünce tarzıyla problem çözebilecek nitelikli insan gücünü yetiştirmek olan lisansüstü eğitim; Türkiye'de Üniversitelere bağlı enstitülerce yürütülmektedir. Lisansüstü eğitim; eğitim kalitesi, ülke kaynaklarının etkin kullanımı ve gelişmişlik düzeyi ile yakından ilişkili olduğu için önemle üzerinde durulması gereken bir konudur. Türkiye'de, lisansüstü eğitimde öğretim üyesi, öğrenci, eğitim programları ve çalışma birimleri ve şartlarıyla ilgili pek çok sorun yaşanmaktadır. Bu çalışma; esas itibariyle lisansüstü eğitimin önemini vurgulayarak, söz konusu bu sorunları genel boyutuyla tespit edebilmeyi ve geliştirilebilecek çözüm önerilerine katkı sağlayabilmeyi amaçlamaktadır.
Effects of two different methyl jasmonate (MeJA) doses, applied 2 weeks ahead of estimated harvest date, on fruit weight loss (%), color, firmness, total soluble solids (TSS), total phenolic (TP), total antioxidant activity (TAA) and individual phenolic compounds of “Fortune” plum were investigated at harvest and during 4 weeks of cold storage. Application of MeJA significantly increased weight loss at the end of storage period. entire color characteristics decreased linearly in all treatments during the storage period. The highest fruit firmness value at the end of storage was obtained from 1,120 mg L−1 MeJA treatment. TP and TAA values increased linearly in all treatments during the storage period.
The highest post‐storage total phenolics and antioxidant values was observed in the 2,240 mg L−1 MeJA application. MeJA applications significantly increased the chlorogenic acid content during the storage (P < 0.05).
Practical Applications
Plum fruits constitute a good source of natural antioxidant substances. Particularly, plums contain large amounts of phenolic compounds and flavonoids having natural antioxidant activity which is effective in human diet. results of the study indicated that there was a linear relationship between total phenolic and antioxidant activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
