In this study the effects of different treatments were investigated for the purpose of storage of cut narcissi for improving marketing opportunities. Flowers of a wild population of single flowered Narcissus tazetta L. from İzmir/Seferihisar which of the flowers are collected and sold in that region and a double flowered cultivar of N. tazetta L. cv Karaburun Nergisi were used. Two experiments were carried on. Experiment I: After harvest as hydration experiment flowers were hydrated for 7 hours: in in tap water (U1) (Control), in silver thiosulfate (S.T.S) (22.5 ppm) solution (U2) or in S.T.S (22.5 ppm)+ 8-hydroxyquinoline citrate (8-HQC) (150 ppm) + sucrose (%5) solution and their vase and mean floret life were compared. Experiment II: The flowers applied with U1, U2, and U3 treatments during hydration were taken up in tap water and as fourth treatment flowers those applied same solution with U3, wrapped in newsprint and then polyethylene without water (U4). And vase and mean floret life of flowers of these four treatments (U1, U2, U3 and U4) were determined after different storage durations. Four different storage durations (2, 4, 6, and 8 week) at 0 ± 1 °C were investigated. The effects of treatments on vase and floret life were examined. Solutions those were used for hydration increased the vase life of both culture and wild narcissi with respect to control before storage. Positive effects of these treatments were also determined at different storage durations. Culture narcissus showed the highest vase life with U4 treatment which was followed by U3, U2 and with the lowest value U1 (control). The results of three treatments (U2, U3, and U4) were placed in the same statistical group for the flowers of wild narcissus which were higher than control (U1). It was determined that the longer the storage time was shortened the vase life but even after a long storage period of eight week, satisfactory vase life values (4,6 – 5,1 day) were obtained from both wild and culture narcissi

Çalışmada, kesme çiçek nergisin, yoğun olduğu dönemlerde depolanıp, piyasada ürünün azaldığı veya olmadığı dönemlerde değerlendirilmesini sağlamaya yönelik uygulamalar denenmiştir. İzmir Seferihisar’da Narcissus tazetta L. türüne ait, yörede çiçekleri toplanarak pazarlanan, çiçekleri yalın katlı olan bitkilerden oluşan doğal bir popülasyonun ve İzmir Karaburun’da N. tazetta L. türünün katmerli çiçeklere sahip olan bir kültür çeşidinin (Karaburun Nergisi) çiçekleri kullanılmıştır. İki deneme yürütülmüştür. Deneme I: Hasat edilen çiçekler su çektirme aşamasında 7’şer saat süre ile, çeşme suyunda (Kontrol) (U1), gümüş tiyosülfat (GTS) (22,5 ppm) çözeltisinde (U2) veya G.T.S (22,5 ppm) + 8-hydroxyquinoline citrate (8-HQC) (150 ppm) + sakkaroz (%5) çözeltisinde (U3) tutulduktan sonra ölçümler yapılmıştır. Deneme II: Su çektirme aşamasında U1, U2 ve U3 uygulanan çiçekler çeşme suyuna alınarak, bir dördüncü uygulama olarak U3 ile aynı çözelti çektirilen çiçekler, susuz, üçüncü hamur kağıda ve polietilen silive sarılı olarak 0 ± 1 °C’deki karanlık soğuk depoya alınmıştır. Dört farklı depolama süresi (2, 4, 6 ve 8 hafta) denenmiştir. Uygulamaların vazo ve ortalama çiçekçik ömrü değerlerine etkileri incelenmiştir. Su çektirme aşamasında kullanılan çözeltiler Karaburun Nergisi ve doğal nergiste vazo ömrünü depolama öncesi kontrole göre uzatmıştır. Bu uygulamaların olumlu etkileri farklı depolama sürelerinde de kendisini göstermiştir. Karaburun Nergisinde vazo ömründe en yüksek değer U4’ten alınırken bu uygulamayı sırayla U3, U2 ve en düşük değere sahip olan U1 takip etmiştir. Doğal nergiste ise üç uygulama da (U2, U3, U4) aynı değerlere sahip olmuş ve yine U1’in önünde yer almıştır. Depolama süresi uzadıkça vazo ömrünün azaldığı belirlenmiş ancak 8 haftalık uzun bir sürenin sonunda doğal ve kültür orijinli nergis çiçeklerinin her ikisinde de vazo ömrü, kayda değer seviyelerde (4,6 – 5,1 gün) kalmıştır
