Abstract: Photosynthetic rate, Water use efficiency and leaf wideness were compared among eight wheat varieties differing phosphate use efficiency by using stable carbon isotope technique and portable photosynthetic apparatus. Under water stress conditions, leaf wideness, dry weight per leaf and net photosynt
