Abstract :In this study, the responses of the most frequently used grass plants in landscape areas to drought were determined. To ensure the continuity of grass areas and to keep them green in all seasons, mixtures are widely used instead of a single species. Therefore, eight different grass mixtures were used as experimental material. The experiment was carried out under laboratory conditions at two different temperatures, 20ºC±1 and 30ºC±1. The plant was put into water stress by applying four different irrigation treatments at both temperatures. The four different irrigation treatments were determined as completing the lost moisture to the pot capacity when 40±5% of the usable water holding capacity was consumed (control) and 75%, 50% and 25% of the water applied to the control subject. Plant water consumption of grass mixtures was determined under different temperatures and irrigation treatments and changes in their visual quality were examined. Plant water consumption values varied between 3.5 and 2 mm for 20ºC±1 and 4.4 and 2.0 mm for 30ºC±1. No significant difference was observed between the varieties in terms of plant water consumption values at both temperatures. Since the I75 treatments of the 4M-JG, 4M-J, 4M-S, 4M-D and 7M varieties were above the visual quality limit at 30ºC±1 temperature, it was determined that 25% water restriction could be applied to these varieties. At 20ºC±1 temperature, it was observed that the I100, I75 and I50 subjects of all varieties were above the acceptable visual quality limit.
