This research was conducted in the Laboratory of Pollution and Plant eenvironment in ddepartment of Plant bbiology, Faculty of Sciences, University of Aleppo. The aim of this research is to study the effect of chromium element on growth indicators of <em>Zea mays<\/em> seedlings. The seeds were treated with a series of graduated concentrations of potassium dichromate (25-50-100-200-400) mg. Seed germination indicators represented by germination percentage, dry and wet shoots and roots lengths and weights of maize seedlings were studied. Where all the indicators of seed germination decreased in all the studied concentrations, and the two concentrations (200-400) mg \/ L had the greatest effect as the roots were burned and died.<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times;\"><strong>Keywords<\/strong>: Chromium, K<sub>2<\/sub>cr<sub>2<\/sub>o<sub>7,<\/sub> potassium dichromate , Phenotypic traits<em>, <\/em>\u00a0<em>Zea mays.<\/em><\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times;\">Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v91p14.pdf\">pdf<\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Aya Azzam(1) *, Aya Kanawaty (1) and Imad aldeen AlKhalaf (1) (1).
