Description
Summary: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.
