Effects of Cold Stress on Enzyme Activities in Peas

Abstract

This research was conducted in three replications according to the ''Two Factor Factorial Experiment in Random Plots'' design and Selcuk University, Faculty of Agriculture, Department of Field Crops, in a fully controlled research greenhouse and laboratories in 2015. Pea genotypes resistant to cold stress were determined, and biochemical, physical properties or physical defense mechanisms created by plants against cold stress were sought. According to the results of the research, if cold harm was examined, Melrose, Sahin, Granger, 4053 x Melrose, 4053 x Hadim, Sahin x Hadim and 3057 x Melrose; if peroxidase content was examined 3057 x Melrose, 4053 x Melrose, 3029 x Melrose, 3029 x Granger and 4053 x Hadim, when superoxidase content was examined, 3053 x Melrose, Sahin x Hadim, 4053 x Melrose, Sahin x Melrose and 3029 x Melrose and when proline content examined 3031 x Granger, 3055 x Melrose, Ultrillo, 3057 x Hadim and Sahin x Hadim the genotypes were first. As a result, when the effects of cold stress on the enzyme activities in the leaves of pea genotypes are considered, the most durable genotypes are 3031 x Granger and 3055 x Melrose. These come forward as genotypes that can be used in subsequent studies to breed for cold resistance.
