Çoban Üzümü (Vaccinium myrtillus L.) TohumlarınınÇimlendirilmesinde Soğuk Katlama, Soğuk Depolama veGibberellik asit (GA3) Uygulamalarının Etkisi

Çalışmanın amacı: Soğuk saklama, soğuk depolama ve gibberellik asidin (GA3) çoban üzümü (Vaccinium. myrtillus L.) tohumlarının çimlenmesi üzerine etkileri araştırılmıştır. Çalışma alanı: V. myrtillus L.’un olgun meyveleri Türkiye de Balıkesir-Kaz dağları Milli Parkı içerisinden toplanmıştır. Materyal ve yöntem: Bu çalışmada +4 °C’de beş seviyeli soğuk nemli saklama, soğuk kuru depolama periyodu (kontrol, 15, 30, 60, 90 günler) ve üç doz (kontrol, 500, 1000, 1500 mg/L) GA3 işlemleri uygulanmıştır. Elde edilen veriler, üç tekerrürlü üç faktöre göre birbirinden bağımsız olarak ANOVA ile test edilmiştir. Her bir işlem ve tekerrür için 50 adet tohum kullanılmıştır. Temel sonuçlar: Soğuk katlama, soğuk depolama ve GA3 işlemleri çoban üzümü tohumlarının çimlenme yüzdesini artırmamıştır. Tüm denemelerde çimlenme oranları %23-40 arasında bulunmuştur. Araştırma vurguları: V. myrtillus L. tohumlarının çimlenme yüzdesini arttırmak için farklı ön uygulamaların yapılması önerilmektedir

The Effects of Cold Stratification, Cold Storage and Gibberellic acid (GA3) on Seed Germination of Bilberry (Vaccinium myrtillus L.)

Aim of study: The effects of cold stratification, cold storage and gibberellic acid (GA3) on seed germination of bilberry (Vaccinium myrtillus L.) were investigated. Area of study: Ripe berries of V.myrtillus were collected from the Kaz Mountains (İda Mount) National Park-Balıkesir province in Turkey. Material and methods: In the study five levels of cold moist stratification period, cold dry storage period (control, 15, 30, 60, 90 days) at +4 ºC and three dose of GA3 (control, 500, 1000, 1500 mg/L) treatments were applied. Data were tested independently by ANOVA according to three factors with three replications. 50 seeds were used for each treatment for each replication. Main results: Cold stratifications, cold storage and GA3 treatments did not increase the germination percentage of bilberry seeds. Germination was found between 23-40% in all experiments. Highlights: Different pretreatments are advised for increasing germination percentage of V. myrtillus L. seeds
