This study was carried out in the Selcuk University Faculty of Agriculture Department of Horticulture Research and practice greenhouse. In the study, Ata77, Bolverim77, Doruk77, Dorukhan77, Eren77, Erenoğlu77 and Hilal77 strawberry varieties obtained from Yalova Atatürk Horticultural Research Institute were used. Sewing 5-6 leaf stage seedlings strawberries made after the arrival of field capacity after the leaves of plants irrigation turgor until drought. After implementation of the varieties of drought with healing and drought period of watering again losses to determine. Leaf relative water content (LRWC) loss 15. by the end of the day up to Ata77 cultivar (51.51%) while the cultivar Dorukhan77 with at least lost 29.74%. Improvement of then 7. day also represents the maximum improvement in the kind of Dorukhan77 (% 5.38), while according to the day of check out lost 17.57% Ata77. Membrane permeability up to Ata77 cultivar (91.32%) while the lowest membrane radicals Doruk77 (71.46%). The drought is finally low stomatal conductivity Ata77 (10.70 mmol m-2 h-1) from the rubrics communicate the highest stomatal conductivity Doruk77 (106.76 mmol m-2 h-1) measured from. Measured in terms of the amount of chlorophyll in leaves, drought and recovery period maximum type of SPAD value from Eren77 (56.52 and 56.73) while Hilal77 the lowest values were obtained from (52.15 and 52.31). Body weight value of relative dry drought at the end of the implementation of the Doruk77 with the highest being obtained from 33.47 g minimum value has been obtained from Ata77 with 24.35 g. In terms of relative root dry weight, the highest value is being obtained from 24.79 g Doruk77 with the minimum value has been obtained from Dorukhan77 with 18.44 g. Leaf after leaf of the drought in the area measuring growth% 2.57 cultivar Dorukhan77 with, while the lowest leaf growth is cultivar has been Doruk77 0.26%.
