Abstract

Two experiments were conducted in 2001 2002 and 2002 2003 growing seasons in a field, 17 kilometers west of Isfahan. The Experimental design was split factorial in randomized complete block with three replications. Four DROUGHT STRESS (S1= full irrigation, S2= withholding irrigation in vegetative growth stage, S3= withholding irrigation in flowering stage, .andS4= withholding irrigation in seed filling stage) were randomized to the main plot units while 12 treatments from combination levels of three cultivars (C1= Zarghan 279, C2= Varamin 295 and C3= LRV 5151) and four FOLIAR APPLICATIONs (F1= no FOLIAR APPLICATION, F2=foliar application of water, F3 = FOLIAR APPLICATION of Zinc Sulfate (3000 ppm) and F4=foliar application of manganese sulfate (3000 ppm» were randomized to the subplot units. Free praline, TOTAL SOLUBLE SUGARS (TSS), SPAD and CHLOROPHYLL FLUORESCENCE were measured in S2 DROUGHT STRESS. Results indicated that DROUGHT STRESS increased praline, TSS and SPAD, but has no effect on CHLOROPHYLL flourescence (fv/fin). In case of praline and TSS significant interactions were found among between FOLIAR APPLICATION, DROUGHT STRESS and cultivars. At full irrigation, foilar application of manganese and zinc could not change praline and TSS in either cultivar. However praline and TSS in Cl increased with zinc and manganese FOLIAR APPLICATION. DROUGHT STRESS also increased SPAD and so did zinc and manganese FOLIAR APPLICATION. Generally Cl had maximum praline, TSS concentration, and SPAD in DROUGHT STRESS condition as well as with zinc and manganese FOLIAR APPLICATION. It was concluded that FOLIAR APPLICATION of micronutrients, such as ZN or MN, under DROUGHT STRESS conditions, could increase drought tolerance in SAFFLOWER.
