Abstract

This research was carried out in 2016 in order to determine the most suitable germination temperatures of the seeds of 4 different forage pea varieties (Furkan, Bilgehan, Özkaynak, Taşkent) stored in paper bags for 7 years and 8 years at room temperature, and the damage that may occur on plants at subzero temperatures after germination were carried out. In the experiment, which was established with 4 replications in the "Random Plots in Factorial Experiment Design" under laboratory conditions; Number of germinated seeds on the 4th, 7th and 10th days at 5°C, 15°C, 25°C and 35°C temperatures, and after the 10th day, frost damage in plants kept at -5°C for 3 days, root length, stem length, root length/stem length ratio was determined. According to the findings of the research, while the best germination took place at 25°C, the most suitable germination temperature was determined between 15°C and 25°C. In addition, it was revealed that the seeds produced in 2008 germinated more than the seeds produced in 2016. On the other hand, among the plants kept at -5°C, it was determined that the varieties named Taşkent and Özkaynak, which were germinated
at 15°C and 25°C, suffered the least damage, and the highest average in the comparison of the total height values was found in the Taşkent variety germinated at 25°C.
