74 Abstract In order to study the effect of irrigation regimes on growth photosynthesis leaf proline content and grain yield of safflower a 4 replicate split plot RCBD field experiment was performed at Lavark Reasrch Farm Isfahan University of Technology Isfahan Iran in 2007 Two Irrigation levels including irrigating after 80 mm I1 control and 140 mm I2 drought evaporation from a Standard Class A Pan were served as main plots Six safflower genotypes including Arak 2811 Kuseh Nebraska 10 C111 S149 and K12 were considered as subplots Gas exchange rate at heading and flowering leaf area index LAI and leaf proline content at 50 flowering head plant seed head 1000seed weight grain and biological yield oil content and oil yield were measured Net photosynthetic rate differed among irrigation levels and genotypes At both heading and flowering stages drought decreased net photosynthetic rate by 51 and 56 at heading and flowering respectively While the net photosynthetic rate was maximum in Kuseh it was minimum in S149 and C111 at both heading and flowering stages Moisture deficit in safflower increased leaf proline content by 83 averaged over genotypes though the leaf proline level was not positively correlated to the grain yield Maximum and minimum proline accumulations were observed in Kuseh and S149 respectively LAI differed among irrigation levels and genotypes Drought decreased LAI by 27 56 A greater seed head 2 21 head plant 35 68 and seed weight 12 34 was observed in I1 compared to the I2 irrigation level Grain yield decreased with drought I1 out yielding I2 by 46 Oil yield and biological yield per plant and per hectare were decreased by irrigation level Among grain yield biological yield and photosynthetic rate indicated the greatest correlation experienced It could be concluded that with genotypes used in this experiment and the environmental conditions in 2007 in Isfahan drought negatively affects both photosynthetic rate and LAI in safflower resulting in significant decreases in grain and biological yield An increased level of leaf proline content under drought is an indicative of the stress level rather than the resistance of this oil seed crop to the later environmental constrain Key word Safflower photosynthetic rate proline grain yield biological yield PDF created with pdfFactory Pro trial version www pdffactory com
