Özet
The purpose of this study was to investigate the resistance of bread and einkorn wheat genotypes under in vitro conditionsagainst drought stress during germination. Twelve bread and ten einkorn wheat genotypes were used as plant material and sevendrought stress levels were appliedbased ona three-replicate factorial restricted randomized block design in order to investigate their effects on germination rate (GR), germinating power (GP), coleoptile length (CL), shoot length (SL), root length (RL), shoot root length ratio (SRLR), root fresh weight (RFW), root dry weight (RDW), and root fresh dry weight ratio (RFDWR) during the year 2014-2015. PEG–6000 was used toevaluate the effect of drought stress under in vitro conditions on the wheat genotypes.The values of all traits were decreasedbytheincreased effect ofPEG levels (p≤ 0.05).The results of the variance analysisshowedthat thegenotypeshadsignificant statistical differences for theexaminedtraits under drought stress(p < 0.05).According to theresults of theGGE biplot analysis, of the total variation between the genotypes and traits investigated under drought stress (75.97%), PC1and PC2 represented51.51% and 24.47%, respectively. In addition, einkorn wheat populationswerelocated inthesector of GR, GP, and SRL,which means that these populations had agreater performance for these traits under drought stress conditions.Bread wheat and einkorn genotypes behaved differently for the traits under drought stress. It is considered that the results of the field and in vivo experiments for cold and drought stresswill contribute toproducingreliable suggestions.
