Erbaa (Tokat) Ekolojik Koşullarında Bazı Gerbera (Gerbera sp.) Çeşitlerinde GA3 Uygulamalarının Verim ve Kalite Üzerine Etkileri
Bu çalışma 2017 yılında Erbaa/Tokat üretici serasında gerçekleştirilmiştir. Farklı dozlarda ( 0, 150, 300, 450 ve 600 ppm) GA3 uygulamalarının Gerbera sp. bitkisinin Yeliz ve Ulaş çeşidinde çiçek sapı uzunluğu, çiçek sapı kalınlığı, çiçek çapı, çiçek ağırlığı, verim, vazo ömrü ve kardeşlenme sayısı üzerine etkilerini belirlemek amacıyla gözlem ve ölçümler yapılmıştır. Çalışma tesadüf parselleri deneme desenine göre 3 tekerrürlü her parsel olarak kurulmuştur. Deneme Mayıs-Eylül ayları arasında ayda bir olmak üzere üç ay (Haziran-Temmuz-Ağustos) yapraklara püskürtme şeklinde doz uygulaması yapılmıştır. Deneme sonunda GA3 uygulamalarının kontrole göre hem verim hem de kalite açısından daha olumlu etkiler meydana getirdiğini göstermiştir. Doz uygulamalarının çeşitler üzerindeki verimi incelendiğinde elde edilen hasatta 300 ppm’lik GA3 uygulamasında Yeliz Çeşidi (14.66 adet/parsel) en yüksek verimin sağlandığı saptanmıştır. Sap uzunluğu GA3 150 ppm doz uygulamasında Yeliz çeşidinde (71.47 cm) elde edilmiştir. Çiçek çapı GA3 150 ppm doz uygulamasından sonra elde edilen bitkilerde Ulaş çeşidinde (133.05 mm), çiçek sap kalınlığı GA3 150 ppm doz uygulamasında Yeliz çeşidinde (6.40 mm), kesme çiçek ağırlığında GA3 150 ppm doz uygulamasında Yeliz çeşidinde (35.935 gr/adet) ölçülmüştür. En uzun vazo ömrü Ulaş Çeşidi GA3 450 ppm doz uygulamasında (16.33 gün) elde edilen çiçeklerde saptanmıştır.
The Effects of GA3 Applications on the Yield and Quality of Gerber Daisy (Gerbera sp.) Cultivars in Erbaa (Tokat) Ecological Conditions
This study was carried out in Erbaa/Tokat in a producer greenhouse in 2017. In this study, observationsand measurements were made in order to determine the effects of GA3 treatment at different doses ( 0, 150, 300, 450and 600 ppm) on Gerbera sp. regarding the length and thickness of the pedicle, flower diameter, cut flower weight,yield, vase life, and tillering count. The study was based on a randomized plots test pattern on three consecutiveplots. The study was conducted in May, and the growth regulator was applied once each month for three months(June-July-August) by spraying it to the leaves. The results indicate that the GA3 treatment had positive effects interms of both the yield and the quality, compared to the control group. Evaluation of the effects of various dosesapplied on the cultivars reveals that the Yeliz cultivar achieved the highest yield with 300 ppm GA3 treatment with14.66 units per parcel. Similarly, the longest pedicle length was also achieved by the Yeliz cultivar (71.47 cm) with150 ppm GA3 treatment. The highest flower diameter was achieved by the Ulaş cultivar (133.05 mm) with 150 ppmGA3 treatment, the thickest pedicle was achieved by the Yeliz cultivar (6.40 mm) at 150 ppm GA3 treatment, and thehighest cut flower weight was achieved by the Yeliz cultivar (35.935 gr/unit) at 150 ppm GA3 treatment. The longestvase life was achieved by the Ulaş cultivar (16.33 days) flowers treated with 450 ppm GA3.
