Süs Bitkilerinde Ön Soğutma Uygulamalarının Önemi ve Kullanım Olanakları

Kesme çiçek sektöründe, çiçeğin kalite parametrelerinin ve vazo ömrünün uzun süre korunması hem ürünün ekonomik değerini hem de satıla bilirliğini artırmak açısından önem taşımaktadır. Benzer şekilde, hasattan sonra soğanlı süs bitkilerinin toprak altı organlarının soğuklama gereksiniminin giderilmesi amacıyla depolanması aşamasında, ürünün hasat sıcaklığından depolama sıcaklığına hızlı bir şekilde getirilmesi önem arz etmektedir. Ürünün kalitesini artırırken kayıpları en aza indirmek için geçmişten günümüze pek çok yöntem geliştirilmiştir. Bu yöntemlerden biri de ön soğutma yöntemidir. Ön soğutma, ürünün hasat sıcaklığından depolama sıcaklığına hızlı ve etkin bir şekilde düşürülmesi olarak tanımlanmaktadır. Ön soğutma, hem ürünün hasat sonrası soğuk depoya konulması hem de depolama yapılmaksızın doğrudan satışa çıkarılması durumlarında, ürünün dayanım süresini ve kalite parametrelerini artırmak için kullanılabilmektedir. Uygulandığı tarımsal ürünlerin yapısal ve fizyolojik özelliklerine bağlı olarak ön soğutma, havayla, suyla ve vakumla olmak üzere temelde üç ayrı yöntemle yapılabilmektedir. Bu çalışmada, ön soğutma yöntemleri süs bitkilerine uygunlukları bakımından detaylı bir şekilde tartışılmıştır.

The Importance of Pre-cooling Methods and Usage Possibilities in Ornamental Plants

In cut flower sector, preservation of flower quality parameters and vase life is very important in terms of both economical value of product and salability of product. Similarly, reaching of product from harvesting temperature to storage temperature quickly is of great importance in stage of eliminating of the chilling requirement the underground organs of bulbous ornamental plants after harvest. Several methods have been developed from the past to the present so as to increase of product quality and to minimize losses. One of these methods is also precooling method. Precooling is defined as fast and effectively lowering of product from harvest temperature to storage temperature. Precooling can be used to increase product quality and storage period in case of both to be put into cold storage after harvest and to be sell directly without storage. Depend on structural and physiological properties of agricultural products; precooling can be divided into three different methods including air, hydro and vacuum precooling. In this study, precooling methods were discussed in detail in terms of compliance with ornamental plants.
