Abstract

Canola as one of the significant oil-seed plants in mild climates has the capability to adapt itself to a wide range of climatic conditions. Canola oil has a high nutritional quality due to its unsaturated fatty and cholesterol-free acids. From among different kinds of oil-seed plants, canola has a high degree of variability in its fatty acids. The present study investigated the effect of different concentrations of LEAD (pbCl2) and ZINC (ZnCl2) on some of the GROWTH PARAMETERS of BRASSICA NAPUS L. A number of similar seeds were selected for the study. Two ml of zn, pb solutions and distilled water (as check) were added to each plate containing five seeds. The plates were then incubated in darkness at 25oc . The solutions were arranged everyday and the germination speed was measured after 3 to 4 days. After the germination, the plates were kept under the same condition for 10 to 14 days. Afterwards, the grown seeds were taken out of the plates and their wet weight was measured. The dry weight was counted after 72 hours. After twenty days of cultivation, the seed were treated with different concentrations of pbcl2 (0.50, 2.50, 4.50 and 6.50) and zncl2 (5.0, 10.0, 15.0 and 20.0) for 45 days and then were used for investigating the GROWTH PARAMETERS. An increase in the amount of the LEAD and ZINC of the cultivation environment resulted in a decrease in the percent and rate of germination, the wet and dry weights, the root length, and the hipocuticule length in all of the treatments.
