Erzincan Koşullarında Yetiştirilen ‘Ak Sakı’ Elma Çeşidinin Depolama Performansı Üzerine Hasat Öncesi Naftalen Asetik Asit ve Aminoetoksivinilglisin Uygulamalarının Etkileri

Bu çalışma, ‘Ak Sakı’ elma çeşidinin (Malus domestica Borkh.) depolama performansı üzerine hasat öncesi dönemde farklı dozlarda uygulanan aminoetoksivinilglisin (AVG, 150, 225 ve 300 mg/L) ve naftalen asetik asit (NAA, 20 mg/L) uygulamalarının etkilerini belirlemek amacıyla 2012 yılında yürütülmüştür. Bazı meyve kalite parametrelerinde oluşan değişimler, % 90±5 nispi nem ve 2±1 °C depolama koşullarında 45 günlük aralıklar ile izlenmiştir. Depolama süresince en düşük ağırlık kaybı 300 mg/L AVG uygulaması yapılan meyvelerde elde edilmiştir. Tüm analiz dönemlerinde 300 mg/L AVG uygulaması yapılan meyvelerde en yüksek L* değeri, kontrol meyvelerinde en düşük hue açı değeri kaydedilmiştir. Depolama süresince meyve eti sertliğinin en iyi şekilde 225 ve 300 mg/L AVG uygulamaları yapılan meyvelerde korunduğu belirlenmiştir. NAA uygulaması, depolama süresi sonunda meyve eti sertliğini önemli düzeyde düşürmüştür. Depolama süresince suda çözünebilir kuru madde (SÇKM) miktarı kontrol meyvelerinde en yüksek, 300 mg/L AVG uygulaması yapılan meyvelerde ise en düşük bulunmuştur. Tüm analiz dönemlerinde en yüksek titre edilebilir asit miktarı, 225 ve 300 mg/L AVG uygulanmış meyvelerden elde edilmiştir. AVG uygulamaları nişasta parçalanmasını geciktirmiştir.

The effects of pre-harvest napthalene acetic acid and aminoethoxyvinylglycine treatments on storage performance of ‘ Ak Sakı’ apple cultivar grown in Erzincan conditions

This study was carried out to determine the effects of pre-harvest aminoethoxyvinylglycine (AVG, 150, 225 ve 300 mg/L) and naphthaleneacetic acid (NAA, 20 mg/L) treatments in different doses on storage performance of ‘Ak Sakı’ apple cultivar (Malus domestica Borkh.) in 2012. The changes on some fruit quality parameters were measured at 2±1 oC temperature and with 90±5 % relative humidity at 45 days interval during storage. The lowest weight loss was obtained from 300 mg/L AVG treated fruits during the storage. In the all analysis date, the highest L* value was obtained from 300 mg/L AVG treated fruits, and the lowest hue angle value was reported from the fruits of control treatment. The flesh firmness was determined that the best kept in the 225 and 300 mg/L AVG treated fruits during the storage. The flesh firmness significantly reduced with NAA treatment at the end of storage. The highest soluble solids concentration (SSC) was obtain from control fruit during the storage, whereas the lowest SSC was observed in fruit treated with 300 mg/L AVG. In the all analysis date, the highest titratable acidity was obtained in fruits treated with 225 and 300 mg/L AVG. The starch degradation was delayed with AVG treatments.
