Abstract

Because of the importance of water stress influence on plant growth, metabolism and yield, Satureja hortensis L. was imposed towater stress treaments. Irrigation treatments were selected basis on the different percentage of field capacity (FC), including (i) a control which was irrigated to full field capacity during the growing season (FC), (ii) two moderate water stress treatments during vegetative (LS1) and flowering stages(LS2)and (iii) severe water stress treatments during flowering stages(HS). Results showed that plant water potential reduced from -0.5 to 1.5 Mpa and RWC (relative water content) decreased too. Also water stress induced high amount of proline. The amount of proline was the highest in sever treatment while it changed from 0.69 to 7.36 μ M/g FW in FC, LS2 treatments.
