Abstract

Two experiments were conducted in order to evaluate reaction of summer SAFFLOWER to different of intensities drought stress at Isfahan region. Three LINEs of SAFFLOWER selected from Isfahan land race (Isfahan-8, Isfahan-22 and Isfahan– 44) were planted at three densities (31, 20 and 13.3 pm-2) under four irrigation regimes (after 70, 140 and 210 milimeters evaporation from calss A pan until maturity and after 140 milimeters evaporation untill full flowering). Planting was done in north- west of Isfahan uzing a rondomized complete block design with a split-split plot layout and three replications during 2001 and 2002. The effects of drought stress on some characteristics including plant height, branching height, number of secondry-branch per plant, number of heads per plant, LAI, total CGR, NAR, flower yield, grain yield, oil yield and HI were studied. The results showed that decreased water supply in SAFFLOWER canopy caused an intensive stress in canopy. Drought- stress in both years, decreased significantly all characteristics under study except NAR and HI that were increased.In both years, at the first level of drought stress, (Irrigation after 140 milimeter evaporation until maturity), the reaction of SAFFLOWER to drought stress was considerable, however with increase in drought stress intentsity, reaction of SAFFLOWER to stress decreased. Therefore, it could be concluded that SAFFLOWER requires adequate water for optimun growth and production this plant adapts to deficient water conditions.
