Effect of Temperature and Storage Time on Germination in Forage Peas

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.
