Popis: Background: Legumes are the second among all the families in terms of varieties and Vicia genus is the third genus within the Leguminosae family. The germination and emergence rates decrease due to some reasons such as non-homogeneous genetic structure of seed or effect of environmental factors on it. For this reason, some quality problems occur. Quality enhancing applications are performed for seeds to have the desired quality levels in seeds and eliminate the problems. The aim of the present study was to determine the viability of Vicia freyniana Bornm. seeds by different priming treatments. For this purpose, the effect of different chemicals in different doses and periods and at what rate the hot water treatment would affect testa dormancy were studied. Methods: This study was conducted in Uşak University Agriculture and Natural Sciences Faculty Research laboratory in 2019. An investigation was conducted to determine the effects of the priming treatments (Soaking and imbibation; 2, 4 and 6% doses of NaCl, CaCl2 and KNO3 salts and 75, 100 and 125 ppm doses of GA3) on seeds of Vicia freyniana Bornm. In the study, the germination rate (%), germination speed (day), germination index (day) and EC values (µS/cm g-1) of the V. freyniana seeds were determined. Result: The highest germination rates were obtained from 2% of CaCl2 and 75 ppm of GA3 treatments and the fastest germination was observed in KNO3 treatment. From the study, it is concluded that 2% dose of CaCl2 and 75 ppm dose of GA3 should be preferred in V. freyniana seeds and the impregnation technique should be preferred among priming methods due to its high germination performance.
