Abstract

This study was carried out to determine the effects of some temperatures and dormancy-breaking applications on seed germination rates of camelthorn (Alhagi pseudalhagi) seeds. The research was carried out in the Field Crops Laboratory of the Faculty of Agriculture of Igdir University in 2020. Camelthorn seeds were initially germinated in dark at 10°C, 15°C, 20°C, and 25°C constant and at 20/10°C, 20/15°C, 25/10°C, and 25/15°C variable temperature conditions. It was determined that the highest total and normal germination rates were 33.3% and 28.0%, respectively, at 25/15°C conditions, and the abnormal germination rate was 14.6% at 20/10°C conditions. It was observed that no germination took place in the seeds under constant temperature conditions of 10°C. It was determined that 66.7% of A. pseudalhagi seeds had a dormancy-related germination problem even under the best temperature conditions. For this purpose, 12 different dormancybreaking applications (matrix-priming, hydro-priming, gibberellic acid, potassium nitrate, cold moist stratification, warm moist stratification, warm+cold moist stratification, cold+warm moist stratification, cold water, hot water, mechanical scarification, and chemical scarification (sulfuric acid)) were made to A. pseudalhagi seeds. According to the results of the research, it was determined that gibberellic acid 28.0%, hot water 25.4%, and mechanical scarification 18.7% removed the dormancy in seeds.

Özet

Bu çalışma, Deve dikeni (Alhagi pseudalhagi) tohumlarının çimlenmesi üzerine bazı sıcaklıkların ve dormansi kırma uygulamalarının etkilerini belirlemek amacıyla yapılmıştır. Araştırma Iğdır Üniversitesi Ziraat Fakültesi Tarla Bitkileri Laboratuvarında 2020 yılında yürütülmüştür. Tohumlar başlangıçta 10, 15, 20 ve 25°C sabit ve 20/10°C, 20/15°C, 25/10°C, ve 25/15°C değişken sıcaklık koşullarında karanlık ortamda çimlendirmeye alınmıştır. En yüksek toplam ve normal çimlenme oranlarının sırasıyla %33,3 ve %28,0 olarak 25/15°C koşullarında, anormal çimlenme oranının ise %14,6 ile 20/10°C koşullarında olduğu belirlenmiştir. Tohumların 10°C sabit sıcaklık koşullarında ise herhangi bir çimlenmesinin gerçekleşmediği görülmüştür. Alhagi pseudalhagi tohumlarında en iyi sıcaklık koşullarda bile %66,7 oranında dormansiye bağlı bir çimlenme problemi olduğu belirlenmiştir. Bu amaçla Alhagi pseudalhagi tohumlarına 12 farklı dormansi kırma uygulaması (matrik-priming hidro-priming, giberellik asit, potasyum nitrat, soğuk katlama, sıcak katlama, sıcak+soğuk katlama, soğuk+sıcak katlama, soğuk su, sıcak su, mekanik aşındırma, ve kimyasal aşındırma (sülfürik asit)) yapılmıştır. Araştırma sonuçlarına göre, giberellik asitin %28,0, sıcak suyun %25,4, ve mekanik aşındırmanın %18,7 oranında tohumlardaki dormansiyi kaldırdığı belirlenmiştir.
