چکیده

an investigation of chlorophyll quick fluorsence variations was made in the reaserch field of islamic azad university- karaj in 2007. the experimental design was a split plot one in form of a complete randomized block design with 4 replications. drought stress was cosiderded in three levels of 40%, 60%, and 75%, on the basis of depletion of soil moisture as the main factor and the factor of microelements in three levels of 0, 3, 5 lit/ha. the evaluated traits were chlorophyll fluorsence parameters, rwc, chlorophyll content and cell memberane stability, as well as grain yield in two stages. results, indicated that the stress effects on f0, chla, chlab and gy and also fv/fm, and chlb were significant at the first stage, while in the second stage they were significant on f0 (p
