| Trail conducted in Greenhouse at farm of Field of Crop Dept. College of Agriculture-University of Baghdad, During 2010 and 2011. The aim was to study the absorption and canalization of Uranium-238 and effect on physical characteristics of the plant. Three varieties of Tobacco was used {Criolo (A1), Habana (A2)} for cigar, and SH (A3) for cigarette with two doses of polluted soil {B2 (low dose) 1 kg of polluted soil and B2 (high dose) 2kg of polluted soil} in addition to control treatment (B1). Design of experiment was systematic arrangement of whole plots according to randomized complete block design (RCBD) with three replicates. Data showed that (SH vr.) superior 34% on (Habana vr.) and 26% on (Criolo vr.) in leaf number and Criolo vr. superior in leaf area with 0.08 m2 in the first year, SH vr. and Habana vr. Superior in leaf weight on Criolo vr. 19.2% and 17.2%, respectively. Control treatment superior in leaf number on high dose treatment 24%, and on low dose treatment 23% and in leaf area and gave 0.34 m2 in the first year, while in the second year, high dose not superior in leaf area of plant m2 and in absorption of Uranium-238 and was 227 the Bq.kg-1 while low dose 103 Bq.kg-1 and control 3 Bq.kg_1. In the second year the conclusion of this study was the effect absorber magnitude nuclear radiation of soil contamination in different type tobacco and ability that effect this soil in physical plant conclusion type Habana was the best in absorption of Thorium-234 and was 115.1 Bq.kg-1 . | ||
