Pollution of irrigation water was increased in the recent years by different environmental pollutants i. e., sewage. Seeds of canola (Brassica napus L.) were sown on 28 November 2005 in Iyzimeters, that were filled clay soil. Canola plants were irrigated with 100% and 50% sewage water. Untreated plants (control) were irrigated with Nile water. Anatomical differences of root, stem and leaf of canola plants irrigated with sewage water at the both two levels and the untreated plants (control) were studied. It was found that, irrigation with sewage water reduced the development of vascular tissues in root and stem ofcanola plants, while increased it in the leaves compared with the control. The highest level of sewage water increased root diameter, while the two levels of sewage water decreased the diameter of stem. Scattered groups of cortex cells which had thicker wall~ were appeared in canola root sections of plants irrigated with 100% sewage water. These transformed cells seems to be sclereid cells (sclerification). Other anatomical parameters of canola plants as affected by sewage water irrigation are presented in detail. Generally, these may be explain the effect of irrigation with sewage water on plant growth and yield characters.
