The Effect of Drying of Bread Wheat Seeds Following First Water Uptake on Germination Rate

In semi-arid regions, unfavorable weather conditions are the most important limiting factors for seed germination. The imbibed or germinating seeds in soil can be dried by hot and dry weather. Thus, seeds can largely lose their germination abilities until the next water uptake (called as ‘alatav’ in Turkish). Before drying, the time of the first water uptake by a seed may be more effective on seed viability at the second water uptake for germination. Therefore, this experiment was conducted to identify the first water uptake rates (WU) of seeds of three bread wheat genotypes (Bezotaja, Kirac and 13-BVD-4) per hour during 50 hours and their germination rates (GR) at the second water uptake after drying the seeds for 3-week in laboratory conditions. The results presented here indicated that the WU and GR were significantly affected by genotypes, imbibition time (T) and their interaction (1% probability level). There was also a significant negative correlation between the WU and GR (r** = –0.9295) at all times studied. Furthermore, the germination ability of Kirac lasted longest (for 38th hour) when the WU reached to 160.24%, and it was followed by Bezostaya and 13-BVD-4 genotypes (63.34% at 37th hour and 152.58% 34th hour, respectively).
