92 Effect of Foliar Application of Bulk and Nano Sized of Zn on the Response of Safflower Cultivars to Water Stress Sayed Mohammad Reza Jafari Pabandi Mohammad jafari1@ag iut ac ir February 10 2014 Department of Agronomy and Plant BreedingIsfahan University of Technology Isfahan Iran 84156 83111Degree M Sc Language FarsiMorteza Zahedi m zahedi@cc iut ac ir AbstractThis investigation was conducted outdoors in two separate pot experiments at College ofAgriculture Isfahan University of Technology Iran Each experiment was arranged as factorialbased on a randomized complete block design with three replications In the first experiment theresponses of thirteen safflower genotypes were evaluated to foliar application of bulk and nano sized zinc oxide In the second experiment the effects of bulk and nano sized zinc oxide on foursafflower genotypes Eritra Afghanestani Mesri and Autrishi that showed considerable anddifferent responses to the application of Zn in the first experiment were studied under irrigationlevels based on 50 and 75 percent depletion of available soil water In the first experiment chlorophyll content leaf area shoot dry weight numbers of buttons per plant numbers of grainsper plant 1000 grain weight and grain yield in most evaluated genotypes were significantlyincreased and the extent of increases was different among genotypes The interaction between zincoxide foliar application and genotype was significant for shoot dry weight The increase in shootdry weight due to zinc oxide application varied from 3 to 48 percent The application of nano sizedas compared to bulk form of zinc oxide increased shoot dry weight in some genotypes butdecreased it in some other genotypes In the second experiment chlorophyll and caretonoidcontent leaf area shoot dry weight plant height Zn concentration and shoot dry weight weredecreased but chlorophyll a b ratio and the activities of antioxidant enzymes were increased underirrigation based on 75 compared to irrigation based on 75 percent depletion of available soil water The decrease in shoot dry weight due to water deficit ranged from 16 to 38 percent among differentgenotypes The foliar application of zinc oxide caused significant increases in chlorophyll content caretonoid content and the activities of antioxidant enzymes CAT APEX and POX in the secondexperiment The positive effects of nano sized compared to bulk form of zinc oxide were greateron these attributes The application of nano sized as compared to bulk form of zinc oxideincreased shoot dry weight in Afghanestani 18 and Eritra 22 genotypes but decreased it inMesri 25 and Autrishi 12 genotypes The results from this study showed that there weresignificant differences among safflower genotypes in response to water deficit and that the effect ofnano sized of zinc oxide safflower plants was genotype dependent Key words safflower genotypes irrigation level foliar application zinc oxide nano particles antioxidant enzymes
