The Effects of Methyl Jasmonate, Cytokinin and Lavender Oil Applications on Postharvest Physiology in Apricot Fruit (Prunus armeniaca L.) | Kayısıda (Prunus Armeniaca L.) Metil Jasmonate, Sitokinin ve Lavanta Yağı Uygulamalarının Hasat Sonrası Fizyolojisi Üzerine Etkileri

Apricot (Prunus armeniaca L.) belonging to Rosaceae family is stone fruit. it is enjoyed to be consumed as fresh fruit by many people, but also is preferred as juice, dried fruit and jam. Turkey has an important place in apricot production in the world. The postharvest life of apricot is limited as fresh fruit. In the study, Bebeko apricot variety was used, the fruits were grown in Van ecological conditions and harvested at harvesting maturity. In the current study, we investigated the effect of Methyl Jasmonate (0.2 mM), cytokinin (5 ppm), lavender oil (1000 ppm) , MeJA (0.2 mM) + lavender oil (1000 ppm) and cytokinin (5 ppm) + lavender oil (1000 ppm) on apricot quality parameters such as pH, titratable acidity (TA), soluble solids content (SSC), skin color, antioxidant capacity, total phenolics, respiration rate and ethylene production as well as determined how long the treatments applied to apricot increase storage period. Our findings suggest that the treatments applied to fruit have a beneficial impact on fruit quality comparing to untreated fruit. As a result, MeJA+Lavander oil treated fruit was found to maintain the quality of the product for 35 days; on the other hand, other treatments were found to maintain the quality of the product for 25 days.Apricot (Prunus armeniaca L.) belonging to Rosaceae family is stone fruit. it is enjoyed to be consumed as fresh fruit by many people, but also is preferred as juice, dried fruit and jam.

Sert çekirdekli meyve türlerinden olan kayısı (Prunus armeniaca L.) insanlar tarafından hem taze meyve olarak hem de işleme teknolojisinde meyve suyu, kuru kayısı ve reçel olarak tüketilmesi yaygın olarak tercih edilmektedir. Türkiye kayısı üretiminde önemli bir yere sahiptir. Kayısı taze meyve olarak hasat sonrası ömrü sınırlı olan meyve türleri arasında yer almaktadır. Çalışmada, Bebeko kayısı çeşidi kullanılmış olup, meyveler Van ekolojik koşullarında yetiştirilmiş ve hasat olumunda derilmiştir. Mevcut çalışmada hasat sonrası Metil Jasmonate (MeJA, 0.2 mM), sitokinin (5 ppm), lavanta yağı (1000 ppm), MeJA (0.2 mM) + lavanta yağı (1000 ppm) ve sitokinin (5 ppm) + lavanta yağı (1000 ppm) uygulamalarının kayısının depolanma süre ve kalitesi üzerine etkileri araştırılmıştır. Depolama boyuncu uygulama yapılan meyvelerde pH, titre edilebilir asitlik (TEA), suda çözünür kuru madde miktarı (SÇKM), meyve kabuk rengi, toplam antioksidan kapasite, toplam fenolik madde içeriği, solunum hızı ve dışsal etilen üretim miktarı belirlenmiştir. Sonuç olarak, MeJA (0.2 mM) + lavanta yağı (1000 ppm) uygulamasının ürün kalitesini 35 gün boyunca koruduğu tespit edilirken, diğer uygulamaların ise ürün kalitesini 25 gün koruduğu belirlenmiştir. Elde ettiğimiz bulgular, uygulamaların kontrol meyvelerine göre daha iyi sonuç verdiğini ortaya koymuştur.
