Determination of the effects of some photosynthesis organs removed in the spike period on agricultural traits of bread wheat varieties

This study, conducted in 2018-2019 at Bursa Uludağ University Faculty of Agriculture Application and Research Center, was aimed to determine the effect of removing some photosynthesis organs on the yield and quality characteristics of bread wheat during the spiking period. In the study, 2 bread wheat varieties (Pehlivan and Golia) were used as material, and the research was carried out in randomized split blocks design with three replications. According to the results obtained, the photosynthesis organs removed during the spiking period of the varieties significantly reduced the plant height, spike height, number of spikes per spike, grain number per spike, grain weight per spike, thousand-grain weight, hectolitre weight, sedimentation value, gluten ratio and harvest index values. On the other hand, an increase in protein ratio was observed. The Golia cv., which is a awned cultivar, has been more affected by the applications than the Pehlivan cv., which is an awnless cultivar.
