Abstract
Bu araştırma 1991-1992 yıllarında Uludağ üniversitesi Ziraat Fakültesi Bahçe Bitkileri Bölümü Araştırma Laboratuvarın da yürütülmüştür . Astor karanfili kesme çiçekleri dört olum devresinde (1.devre, kapalı tomurcuk devresi, 2.devre,tomurcuk ucunda çiçek renginin görüldüğü devre, 3.devre,fırça devresi, 4.devre,hasat olumu devresi) hasat edilerek su çektirilmeden laboratuvara getirilmiş ve her devredeki çiçeklerin yarısına 20 saat süre ile ön uygulama (550 mg/L Gümüş ti-yosülfat + 100 g/L Sakkaros ) yapılmış, diğer yarısına ise herhangi bir uygulama yapılmamıştır.Çiçekler Botrytis'e karşı % 01'lik Baykor ile ilaçlandıktan sonra, polietilen torbalar içinde O’C'de kuru olarak depolanmışlardır. İlki uygulamadan hemen sonra ve onu takiben her 30 günde bir depodan çıkarılan tomurcukla!’ hasat olgunluğu ki çiçekler ise ortalama 30 günlük depolama süresiyle en düşük depolama süresine sahip olmuşlardır. 2- Kimyasal madde ön uygulaması yapılan çiçekler 6.00 günlük vazo ömrüne sahip olurken, ön uygulama yapılmayan çiçeklerin vazo ömrü 5.45 gün olmuştur. 3- 4.Devre çiçekleri 7.4 günle en uzun vazo ömrüne sahip olurken,o-nu 6.8 günle 3.devre ve. 4.6 günle 2.devre çiçekleri izlemiştir, l.dev re çiçekleri ise 3.8 günle en kısa vazo ömrüne sahip olmuşlardır. 4- Çiçeklerin depolanma süreleride vazo ömründe etkili olmuştur.Hiç depolanmayan kontrol çiçekleri ortalama 6.88 günlük vazo ömrüne sahip olurken, bunu istatistiki olarak aynı grupta yer alan 1 ay (4.89 gün) 2 ay (4.53 gün) ve 3 ay (4.85 gün) depolanan çiçeklerin vazo ömrü değerleri izlemiştir. 5- Tomurcuklarm solüsyon içindeki açma süresi dikkate alındığında kimyasal madde ön uygulaması yapılan çiçekler ortalama 7.3 günde hasat olumu devresine gelirken, ön uygulama yapılmayan çiçekler 8.0 gün de hasat, olumu devresine gelmektedirler. Çiçek hasat devreleride açma süresinde etkili olmuştur.Sıkı tomurcukla!' 13.0 günde hasat olumu dev resine gelirken, 2.devre çiçekleri 7.3 günde hasat olumu devresine gelmişlerdir.Fırça devresindeki çiçekler ise 2.3 günle en kısa sürede hasat olumu devresine gelmişlerdir.Tomurcukların açma süresinde etkili olan biz* diğer faktörde çiçeklerin depolanma süresidir. 2 ay depolanan çiçekler 6.35 günde açarken, bunu 1 ay depolanan çiçekler(7.78 gün) ve depolanmayan kontrol çiçekleri (7.82 gün) izlemektedir.3 ay depolanan çiçekler ise 14.80 günle en uzun sürede hasat olumu devresine gelmişlerdir. 6- ön uygulama yapılan çiçekler 5.9 cm'lik çiçek çapına sahip olur-devresine gelinceye kadar, 4.devre çiçekleri ise yarım saat süre ile 200 mg/L 8-Hydroxyquinoline sülphate + 25 mg/L Gümüş nitrat +70 g/L Sakkaros solüsyonunda bekletilmişlerdir.Çalışma süresince karanfil çiçeklerinin, depolanma süresi, tomurcuk açma süresi, vaso ömrü ve çiçek çapı değerleri saptanmıştır.Buna göre; 1-Çiçeklerin depolanma süresi dikkate alındığında; kimyasal madde ön uygulaması yapılan çiçeklerle ön uygulama yapılmayan çiçeklerin depolanma süreleri istatistik! olarak aynı grupta yer almıştır.ön uygulama yapılan çiçekler 60 gün depolanırken, ön uygulama yapılmayan çiçekler 67.5 gün depolanmışlardır. Çiçeklerin hasat devreleri de depolama süresinde etkili olmuştur. Sıkı tomurcuk devresindeki çiçekler ortalama 105 günle en usun süre depolanırken, bunu 60 günlük depolama süresiyle 2. ve 3. devre çiçekleri işlemiştir.Hasat olumu devresinde ken, ön uygulama yapılmayanlar 5.7 cm'lik çiçek çapma sahip olmuş-lardır. 7- 3.Devre çiçekleri 6.1 cm ile en büyük çiçek çapma sahip olurken bunu 5.9 cm ile 2.devre çiçekleri ve 5.7 cm ile 1.devre çiçekleri işlemiştir. 4.devre çiçekleri ise 5.5 cm ile en küçük çiçek çapma sahip olmuşlardır. 8- Depolanan çiçeklerin çapları depolanmayan kontrol çiçeklerinden yüksek bulunmuştur. En yüksek çiçek çapı 6.29 cm ile 2 ay depolanan çiçeklerden elde edilmiştir, bunu istatistik! olarak aynı grupta yer alan 1 ay (5.90 cm) ve 3 ay (5.89 cm) depolanan çiçekler işlemiştir. Hiç depolanmayan kontrol çiçekleri ise 5.54 cm ile en küçük çiçek çapma sahip olmuşlardır.
This research was conducted in the Research Laboratory of Uludağ University Faculty of Agriculture Department of Horticulture in 1991-1992. Cut flovers of carnation cv. Astor vere harvested at 4 maturity stages (l.stage.i.e.closed bud stage, 2.stage,i.e. the stage at vhich the colour of flover appread at the bud tip, 3.stage, i.e. the paint brush stage, 4.stage,i.e. the harvest maturity stage) and brought in-to laboratory vithout putting into vater, and half of the flovers at each stage vere pre-treated for 20 hours (550 mg/L STS + 100 g/L Suc-rose) vhile the other half vere left untreated.The flovers vere tre-ated vith 01 % Baykor and then dry stored in polyethylene bags at o 0 + 0.5 C.The buds vhich vere taken out of storage, first being just after the treatment and then every 30 days vere heİd in a solution of 200 mg/L 8-hydroxyquinoline sulphate + 25 mg/L silver nitrate + 70g/L sucrose till harvest maturity, vhile 4 th stage flovers vere held for half an hour in this solution.The storage period, bud opening period, vase life and flover diameter values vere detarmined along the study 1-When the storage period is considered, the storage period of flovers that vere pretreated vith Chemicals and that of non-pretrea-ted are in the same statistical group. The pretreated flovers vere stored for 60 days vhereas the non-pretreated ones vere stored for 67.5 days.The harvest stage of flowers were effective on the storage period. The flovers at tight bud stage were stored longest with an average of 105 days, this was followed by 2. and 3. stage flov?ers with 60 days,Flowers at harvest maturity stage had the lowest storage period with an average of 30 days. 2- Flowers pretreated with Chemicals had an average vase life of 6 days, while the non-pretreated flowers had a vase life of 5.45 days 3- Flowers at harvest maturity stage had the largest vase life with 7.4 days average and these were followed by the 3 rd stage flo-wers with 6.8 days and by the 2 nd stage flowers with 4.6 days. The first stage flowers had the shortest vase life wit.h 3.8 days. 4- The storage periods of flowers were also effective on vase life. The non-stored control flowers had an average vase life of 6.88 days and these were folloraed by the flowers stored for 1 month (4.89 days) 2 months (4.53 days) and 3 months (4.85 days), these three values we-re in the same group statistically. 5- When the opening period of the buds in the solution was conside-red, the flowers pre-treated with chemiccels came to the harvest maturity stage in 7.3 days average, »hereas those non-pretreated came tb the same stage in 8 days.Flower harvest stage were also effective on opening period.The tight buds came to the harvest maturity stage in 13.0 days, while the 2 nd stage flowers came to this stage in 7.3 days.The flowers at paint brush stage came to the harvest maturity in the shortest time with 2.3 days.Another factor effective on the opening period of flowers is the storage period of flowers. Flowers stored for 2 months opened in 6.35 days and this was follorced by the flowers stored for 1 month (7.78 days) and non -treated control flo »ers (7.82 days).Flowers stored for 3 months came to the harvest ma-turity stage in the largest period »ith 14.80 days. 6- The pretreated flovers had diameter of 5.9 cm, »hile the non-pretreated ones had a diameter of 5.7 cm. 7- The 3 rd stage flb»ers had the largest diameter »ith 6.1 cm and this »as followed by the 2 nd stage flowers »ith 5.9 cm and the 1 st stage flo»ers »ith 5.7 cm.The 4th stage flowers had the smallest diameter »ith 5.5 cm. 8- The diameters of the stored flowers were found higher than the /~ non-stored control flo»ers. The largest flo»er diameter »as obtained from the flo»ers stored for 2 months »ith 6.29 cm, these »ere follo-wed by the flo»ers stored for 1 month (5.90 cm) and 3 months(5.89 cm) »hich »ere in the same group statistically.
