Özet:

In the present study, threelocal tomato genotypes:Yarbasi, Tepekoyu andFereng (Solanum lycopersicum); and one commercial tomato variety:CamentaF1,were subjected to dry stress (100%, 50%, 25%) through controlled irrigation after the first flowering of the tomato plant. The experiment was carried out with four replicates,and with eightplants per replicate. A statistically significant difference was observed between drought stress administered and the methods of administration compared to the control plants only in the drought stress administered in the amount of chlorophyll. The total yield of the Fereng tomato genotype indicated that both stresses were less affected by 50% and 25% drought stress. It carried out to be significantly reduced (50% and 25%) in both dry stresses.
