Aims: The aim of this study is to determine the most appropriate dormancy breaking method and germination temperature in some weed seeds (hoary cress or whitetop (Cardaria draba (L.) Desv.), annual nettle (Urtica urens L.) and black henbane (Hyoscyamus niger L.)).Methods and Results: The most appropriate germination conditions of whitetop, annual nettle and black henbane weeds were determined by applying different dormancy breaking methods (acid-base (sulfuric acid (1, 2, 15, 30, 60 and 90 min), hydrochloric acid (5, 15, 30 and 60 min), sodium hydroxide (50%, 40%, 30% and 20% concentrations 5 , 10, 15 and 20 min) and sodium hypochlorite (5, 10, 15 and 30 min), hormone (gibberellic acid (250, 500, 750 and 1000 ppm)), alcohol (ethanol (5, 15, 30, 60, 90 and 120 min)) and high-low temperature (microwave (10, 30, 45, 90 and 180 sec), and cold storage (0 day control, 1 day -86°C, 2 days -86°C, 4 days -86°C and 7 days -86°C) and cold soaking + hot water (0 days 90°C, 1 day -86 / 90°C, 2 days -86/90°C, 4 days -86/90°C and 7 days -86/90°C) and then the most suitable dormancy breaking method and germination temperatures were determined in the seeds of these weeds.Conclusions: According to the results obtained, the most effective dormancy breaking treatments in seeds of whitetop, annual nettle and black henbane were determined as gibberellic acid 500 and 2000 ppm, gibberellic acid 250 ppm and 30% sodium hydroxide 20 minutes respectively.

Özet

Amaç: Bu çalışmanın amacı, bazı yabancı ot (kır teresi (Cardaria draba (L.) Desv.), küçük ısırgan (Urtica urens L.) ve kara banotu (Hyoscyamus niger L.)) tohumlarında en uygun dormansi kırma yönteminin ve en uygun çimlenme sıcaklığının belirlenmesidir. Yöntem ve Bulgular: Değişik dormansi kırma yöntemleri uygulanarak (asit-baz (sülfürik asit (1, 2, 15, 30, 60 ve 90 dk), hidroklorik asit (5, 15, 30 ve 60 dk), sodyum hidroksit (%50, %40, %30 ve %20 konsantrasyonlarda 5, 10, 15 ve 20 dk) ve sodyum hipoklorit (5,10, 15 ve 30 dk)), hormon (giberellik asit (250, 500, 750 ve 1000 ppm)), alkol (etanol (5, 15, 30, 60, 90 ve 120 dk)) ve yüksek-düşük sıcaklık (mikrodalga (10, 30, 45, 90 ve 180 sn), ve soğukta bekletme (0 gün kontrol, 1 gün -86°C, 2 gün -86°C, 4 gün -86°C ve 7 gün -8°C) ve soğukta bekletme + sıcak su (0 gün 90°C, 1 gün -86/90°C, 2 gün -86/90°C, 4 gün -86/90°C ve 7 gün -86/90°C)) uygulamaları yapılmıştır. Kır teresi, küçük ısırgan ve kara banotu yabancı otlarının en uygun çimlenme özellikleri ortaya konulmuş daha sonra bu yabancı otların tohumlarında en uygun dormansi kırma yöntemi ve çimlenme sıcaklıkları belirlenmiştir. Genel Yorum: Elde edilen sonuçlara göre en uygun dormansi kırma yöntemi olarak: kır teresi için giberellik asitin 500 ile 2000 ppm dozları, küçük ısırgan için 250 ppm giberellik asit belirlenirken, kara banotu tohumlarında ise %30 sodyum hidroksit içerisinde 20 dk tohumların bekletilmesidir. Yabancı otların en uygun çimlenme oranları ise, kır teresi ve kara banotunda 20°C, küçük ısırganda ise 25°C olarak bulunmuştur. Çalışmanın Önemi ve Etkisi: Elde edilen sonuçların bu yabancı otların tarım içi ve dışı alanlarındaki çalışmalara bir alt yapı sağlayacağı beklenmektedir.
