Effective Solutions for Extending Vase Life in Cut Gerbera Flowers

Abstract

One of the critical quality criteria in cut flower marketing is vase life. The neck bending issue observed in gerbera flowers can substantially reduce vase life. This study aimed to identify effective vase solutions to prolong the vase life in the ‘Yeliz’ and ‘Rosalin’ gerbera varieties. Seven different vase solutions were evaluated: sodium dichloroisocyanurate (DICA), sodium hypochlorite (klorak), sodium hypochlorite + sucrose, 8-hydroxyquinoline citrate (8-HQC), perlan + sodium hypochlorite, and perplex + sodium hypochlorite and potable water (Ks: control). Parameters such as vase life, total and daily solution uptake, relative fresh weight, and microbial density in vase solutions were assessed. Vase life ranged from 8.33 to 13.22 days for the ‘Yeliz’ variety and from 10.00 to 14.67 days for the ‘Rosalin’ variety. DICA provided the longest vase life for both varieties among the seven different vase solutions. All vase solutions except for flowers in control improved relative fresh weight within the first 3 days. DICA was also the most effective in reducing microbial density in the vase solutions. Furthermore, all treatments significantly reduced microbial density compared to the control. The findings suggest that substances such as DICA, perlan, and perplex could serve as viable alternatives in vase solutions for extending the vase life of gerbera flowers.

Kesme Gerbera Çiçeklerinde Vazo Ömrünü Uzatan Etkili Solüsyonlar

Öz

Kesme çiçeklerin pazarlanmasında en önemli kalite kriterlerinden biri vazo ömrüdür. Gerbera çiçeklerinde görülen boyun bükme problemi, vazo ömrünü önemli ölçüde kısaltabilmektedir. Bu çalışma, ‘Yeliz’ ve ‘Rosalin’ gerbera çeşitlerinde vazo ömrünü uzatmaya yönelik potansiyel vazo solüsyonlarını belirlemeyi amaçlamıştır. 7 farklı vazo solüsyonunun [sodyum dikloroizosiyanürat (DICA), sodyum hipoklorit (klorak), sodyum hipoklorit + sakaroz, 8-hidroksiquinolin sitrat (8-HQC), perlan + sodyum hipoklorit, perplex + sodyum hipoklorit, içme suyu (Ks, kontrol)] denendiği araştırmada; vazo ömrü, toplam ve günlük solüsyon alımı, oransal taze ağırlık ve vazo solüsyonlarında mikrobiyal yoğunluk parametreleri incelenmiştir. Vazo solüsyonları arasında ‘Yeliz’ çeşidinin vazo ömrü 8.33 gün ile 13.22 gün, ‘Rosalin’ çeşidinin ise 10.00 gün ile 14.67 gün arasında değişmiştir. Her iki çeşit içinde DICA uygulaması en uzun vazo ömrüne sahip uygulama olmuştur. İçme suyu içeren vazolarda bekletilen çiçekli dallar hariç tüm vazo solüsyonlarının, oransal taze ağırlıkta ilk 3 güne kadar artış sağladığı saptanmıştır. Vazo solüsyonlarındaki mikrobiyal yoğunluğu azaltma/önleme bakımından da DICA’nın en başarılı uygulama olduğu belirlenmiştir. Bunun yanında diğer tüm uygulamaların da kontrole göre mikrobiyal yoğunluğu önemli ölçüde azalttığı tespit edilmiştir. Elde edilen sonuçlar, gerbera çiçeklerinde vazo ömrünün uzatılmasında başta DICA olmak üzere, perlan ve perplex gibi maddelerin vazo solüsyonları içeresinde kullanılabilecek alternatif maddeler olarak rol oynayabileceğini göstermektedir.
