Abstract :It is important to identify plants with high drought resistance to minimize irrigation water in landscape areas. The experiment was carried out for six months at Çanakkale Onsekiz Mart University COSMOTLAB. The study aimed to determine the effects of four different irrigation levels [(S100), (S75), (S50), (S25)] on plant water consumption (ET), morphological and phenological parameters of four different miniature rose varieties (Mandarin, Orange Juwel, Zwergen Fee 09 and Zwerkönig 78) frequently used in landscape areas. As a result of the study, according to irrigation levels, the highest flower number values were observed in S100 and the lowest values were observed in 75% water restriction (S25). Water stress caused a decrease in the number of buds and a decrease in flower yield. In addition, it was observed that the flowering performance of the varieties was good even at 25% water restriction (S75) in the miniature rose varieties Mandarin, Orange Juwel and Zwerkönig 78 (except Z09). As a result, it can be said that Mandarin’s ET values (255.7-642.3 mm) are lower than other varieties, the highest plant height value under S50 is reached and when other parameters are evaluated together, it is more resistant to drought than other varieties.
