Abstract: We evaluated drought response of miniature rose Meshkinjan under open door environment during a period of water deficit (21 days) and subsequent rewatering. After 21 days of drought, stem water potential, relative water content, turgid weight to dry weight ratio and starch concentration decreased significantly compared with control. While, the amount of proline and potassium increased significantly that could indicate ability of osmotic adjustment in this species. Also the increase in water potential and relative water content values after rewatering period indicate the good recovery of this plant.
