The purpose of this research was to investigate the effect of zinc on the physiological stress process of spinach plants. Research method: In order to investigate the effect of zinc element on the physiological stress process of spinach plant, a pot experiment was carried out in a factorial form and in the form of a randomized complete block design with three replications.</span><span dir="RTL" style="font-family:"B Nazanin"" lang="AR-SA"></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span calibri="" style="font-family:"><b><span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">Results</span></span></b><b><span lang="EN" style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">:</span></span></b><span new="" roman="" style="font-family:" times=""> The results showed that increasing the concentration of chlorophyll b did not have a significant effect on chlorophyll b values, but caused significant changes in root and aerial parts, chlorophyll a, total chlorophyll and leaf surface. </span><span dir="RTL" style="font-family:"B Nazanin"" lang="AR-SA"></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span calibri="" style="font-family:"><b><span lang="EN" style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">Conclusion:</span></span></b> <span new="" roman="" style="font-family:" times="">According to the findings of the research, this plant can be used in soils contaminated with zinc metal or lands under the wastes of industrial factories to refine this metal.</span><span dir="RTL" style="font-family:"B Nazanin"" lang="AR-SA"></span></span></span></span><br> &nbsp; گیاه پالایی, روی, تنش فیزیولوژیک, اسفناج, Iau Science. plant breeding, zinc, physiological stress, spinach, Iau Science. 61 74 http://ncmbjpiau.ir/browse.php?a_code=A-10-1245-5&slc_lang=fa&sid=1 Allahyar Kamari اله یار کمری 100319475328460013173 100319475328460013173 Yes Department of Biology, Payame Noor University, Tehran, Iran. گروه زیست شناسی ،دانشگاه پیام نور،تهران،ایران.
