Abstract

This study was carried out on three date palm cultivars (Samany, Amhat and Sewy) grown in Abo-Rawash area Giza Gover-norate, Egypt. This work aimed to study the influence of pre-harvest treatments as direct spray on fruits by solutions boron (0.5% in the form of boric acid) and calcium (10 g/L (w/v) in the form of calcium nitrate) alone or in combination to improve quality of date palm fruits during cold storage and increasing marketing period (Shelf life). Fruits were picked in maturity stage and stored at 0.0 ± 1° C and 85 - 90% relative humidity (RH). Fruit quality characteristics i.e. weight loss, decay %, fruit firmness (Lbinch2), total soluble solid percentage (TSS %), total acidity percentage (TA %), total soluble sugars and tannins % were evaluated. Assay of the stored fruits was made at 20 days intervals and additional fruits were left at room temperature (20± 2° C) for one week as stimulated marketing period. The results showed, that all spraying treatments gave the best effect in fruit quality assessments when compared with control. The combined treatment gave the highest v.alue of fruit TSS% and total soluble sugars while decreasing TA% weight loss % and fruit decay %> during cold storage for 40 days. Furthermore, the same trend was observed after cold storage for week on 20± 2° C. It can be recommended spraying date palm fruits twice with the combined treatment of 0.5% boric acid + 10 g/L (w/v) calcium nitrate to improve fruit quality during cold storage and shelf life period.

Özet

Bu çalışma; Mısır Giza eyaleti Abo-Rawash bölgesinde yetiştirilen 3 hurma ağacı kültür bitkisi (Samany, Amhat ve Sewy) üzerinde gerçekleştirilmiştir. Bu çalışmada hurma ağacı meyvelerinin soğuk depolama boyunca kalitesini yükseltmek ve raf ömrünü uzatmak için, meyvelerin üzerine tek yahut kombine olarak bor (%0,5 borik asit formunda) ve kalsiyum (10 g/L kalsiyum nitrat formunda) çözeltileri püskürtmek gibi hasat öncesi denemelerin etkisinin araştırılması amaçlanmıştır. Meyveler olgunluk devresinde seçilmiş ve 0.0 ± 1oC ve % 85-90 bağıl nemde depolanmıştır. Ağırlık kaybı, % çürüklük, meyve sertliği (Lb/inch2), % toplam çözünür katı madde (% TSS), % toplam asitlik (% TA), toplam çözünür şeker ve % tannins gibi meyvenin kalite özellikleri belirlenmiştir. Depolanmış meyvelerin analizleri 20 günlük aralıklarla yapılmış ve ilave meyveleri oda sıcaklığında (20±2oC) 1 hafta raf ömrü için bırakılmıştır. Bütün püskürtme denemelerinin, kontrol örnekleri ile karşılaştırıldığında meyvenin kalite özellikleri üzerine en iyi etkiyi verdiği belirlenmiştir. 40 günlük soğuk depolama boyunca, kombine denemelere maruz bırakılan meyvelerin % TSS ve toplam çözünür şeker miktarları en yüksek değeri verirken, % TA, % ağırlık kaybı ve % meyve çürüklüğünün düştüğü belirlenmiştir. Bununla beraber, aynı eğilim soğuk depolamadan sonra 20 ±2oC de, 1 hafta gözlenmiştir. Meyvelerin soğuk depolama boyunca kalitesini ve raf ömrünü arttırmak için hurma ağacı meyvelerinin hasat öncesi 2 kez % 0,5 borik asit+ 10 g/L kalsiyum nitrat çözeltileri ile kombine olarak spreylenmesi önerilebilir.
