Dünyada ticareti en fazla yapılan kesme çiçeklerin başında kesme gül yer almakta ve hem kıtalar içi hem de kıtalar arasında taşınmaktadır. Kesme güllerin vazo ömrü; iletim demetlerinin tıkanarak yeterli suyu çekememesi, boyun bükme, petallerde kararma ve solma, hastalık (özellikle kurşuni küf) vb. nedenlerle kısalmaktadır. Çiçeklerin vazo ömrü ise vazo solüsyonlarına ilave edilen koruyucu maddelerle uzatılabilmektedir. Çalışmada bitkisel materyal olarak Rosa hybrida türüne ait ülkemizde ticareti oldukça fazla yapılan kırmızı renkte çiçeklere sahip standart tip çiçekleri olan ‘Samourai’ çeşidi kullanılmıştır. Vazo solüsyonu olarak 4 farklı uygulama [ticari marka çamaşır suyu (%0.2, ACE: ürün bileşimi ˂5 Klor bazlı ağartıcı), Sodyum hipoklorit (75 mg L-1), Chrysal (%0.2) ve 8-hydroxyquinoline (200 mg L-1)] kullanılmış ve sonuçlar distile suyun kontrol olarak kullanıldığı uygulama ile karşılaştırılmıştır. Çalışmada; çiçeklerin vazo ömrü, toplam vazo solüsyon alımı, oransal taze ağırlık, vazo ömrü süresince petal rengi, çiçek çapı ve vazo solüsyonlarındaki pH ve EC değişimleri ile mikrobiyal aktivite incelenmiştir. Çalışmamız %0.2 Chrysal (17.83 gün), %0.2 çamaşır suyu (17.75 gün), 200 mg L-1 8-hydroxyquinoline (12.42 gün), 75 mg L-1 Sodyum hipoklorit (9.17 gün) içeren vazo solüsyonlarının, kontrol (8.0 gün)’e kıyasla çiçeklerin vazo ömrünü önemli ölçüde artırdığını göstermiştir. Sonuç olarak, piyasada ticari olarak kullanılan çamaşır suyunun, dünya kesme çiçek sektöründe ticari çiçek koruyucusu olarak kullanılan Chrysal ürünü kadar kesme gül çiçeklerinin vazo ömrünü uzattığı ve çiçek kalitesini koruduğu belirlenmiştir.

Extending the Vase Life of ‘Samourai’ Cut Rose Variety with Different Vase Solutions

Öz

Cut roses are one of the most traded cut flowers in the world and are transported both within and between continents. The vase life of cut roses is shortened due to reasons such as blockage of vascular bundles and insufficient water absorption, neck bending, blackening and fading of petals, disease (especially lead mould), etc. The vase life of flowers can be prolonged with preservatives added to the vase solutions. In this study, ‘Samourai’ variety of Rosa hybrida species with standard type flowers with red coloured flowers, which is widely traded in our country, was used as plant material. Four different treatments [trademark bleach (0.2%, ACE: product composition ˂5 Chlorine-based bleach), sodium hypochlorite (75 mg L-1), Chrysal (0.2%) and 8-hydroxyquinoline (200 mg L-1)] were used as vase solutions and the results were compared with the control treatment of distilled water. In the study; vase life, total vase solution uptake, relative fresh weight, petal colour, flower diameter, pH and EC changes in vase solutions and microbial activity were investigated. Our study showed that vase solutions containing 0.2% Chrysal (17.83 days), 0.2% bleach (17.75 days), 200 mg L-1 8-hydroxyquinoline (12.42 days), 75 mg L-1 sodium hypochlorite (9.17 days) significantly increased the vase life of flowers compared to control (8.0 days). In conclusion, it was determined that bleach, which is used commercially in the market, prolonged the vase life of cut rose flowers and preserved the flower quality as much as Chrysal, which is used as a commercial flower preservative in the world cut flower sector.
