The present study was conducted to evaluate the dynamics of the water regime in association with morpho-physiological activity in the different pear cultivars during the summer of 2013, such as: water content in leaves (WCL) and annual shoots (WCS), water deficit in leaves (WDL) and annual shoots (WDS), electrolytic leakage (EC), leaf anatomical structure and stomata parameters, total chlorophyll content. There were revealed some pattern in water regime so, regardless of the climatic condition WCL, WCS in all cultivars was decreased from early June to late August, however, WDL and WDS were differed significantly in comparison with WCL and WCS, where WDL seasonally fluctuated in all cultivars except Bartlett, which distinguished with high stable rate and there is an imbalance between WDL and WDS. According to results was not found the significant relationship between water regime and EC, stomata parameters, the anatomical structure and total chlorophyll content of the leaves in the summer period, whereas there RH of air and soil condition was sufficiently moistened which might be protected to show real ability of cultivars. Therefore, pear cultivars cannot show their real ability in water regime and physiology especially under humid condition, and cannot be detected of resistance to stress factor and some patterns which are manifested in the dry season or in special controlled condition experience.
