Studies about the project mainly consists of two stages as plant breeding in the laboratory
and analysis. Within the scope of laboratory studies, germination beds were formed in the Ecophysiology
Laboratory of Eskişehir Osmangazi University, Faculty of Science and Literature and where the growth of
the plants was ensured. Seeds of different genotypes (Kirik, Bayraktar, Aldane, Kenanbey, Seyhan,
Yüreğir89, Uzunyayla, Seri82, Fuatbey, Canik) of
Triticum aestivum L. were used as alive materials.
Within the scope of laboratory studies, some ecophysiological parameters plants indexes. Wheat seeds
belonging to different genotypes were left in germination beds for 14 days and applications were divided
into 7 groups as control (21°C), 25°C, 30°C, 35°C, 40°C, 45°C and 50°C. At the end of the process,
germination experiments were terminated and analyzes were started. As a result of the obtained data from
experiments and analyzes; It was determined that applications above 35 °C inhibited vegetative growth in
studied genotypes. It has been observed that the seeds can tolerate the increasing heat between the
applications of 21-40°C. However, it was determined that the seeds could not tolerate the temperature
especially at 45°C. The increase in seasonal temperatures with global warming has increased the importance
of heat shock resistant cereal genotypes for humanity. Breeding of heat shock resistant genotypes is
recommended to prevent economic losses due to heat shock. This is only possible by determining the high
temperature tolerance genotypes by investigations such as in our study. Afterward, researchers should be
focusing on the breeding of these determined genotypes.
