Abstract

Introduction: In order to evaluate the effect of foliar spraying of zinc and calcium on yield and physiological traits of safflower under lead stress, a factorial experiment based on randomized complete block design was performed in Kerman agricultural and natural resource research and education center in 2014-2015 with three replications. The first factorial included three levels (control, and 0.5 and 1 mM lead spraying), whereas the second and third factorials were spraying zinc sulfate at three concentrations (zero, and 10 and 20μM) and spraying calcium chloride at two levels (zero and 20 mM), respectively. According to the results, grain yield, the 1000-grain weight, leaf dry weight, number of seeds per head, head weight and CHLOROPHYLL content decreased. On the other hand, a significant increase was observed in the activities of catalase and ascorbate peroxidase enzymes and amount of MALONDIALDEHYDE in plants. Moreover, spraying zinc fertilizer in lead treatment resulted in a significant increase in activity of catalase enzyme, reduction of membrane lipid peroxidation, prevention of CHLOROPHYLL destruction and maintenance of grain yield. However, the effect of spraying calcium fertilize in lead treatment was only significant on CHLOROPHYLL content. According to the results of the research, it seems that spraying zinc fertilizer had more effects on improved growth of safflower under lead stress, compared to spraying calcium fertilizer. Therefore, in air pollution with HEAVY METALs (lead), application of zinc sulfate fertilizer can be an effective approach to maintain the growth and production of plants....
