house- waste and industrial waste waters introduce cadmium in potable waters, and under ground waters.
chemical fertilizers specially phosphor have sufficient amount of cadmium. Fertilizers made from phosphate minerals is also one of the source of cadmium pollution. Agricultural lands in many parts of the world are polluted by cadmium as a result of the use of phosphate fertilizers for long time. In this study the effects of cadmium chloride on a number of agricultural Brassica napus kinds is under taken, with following points. 1. Cadmium effect on sprouting in petri dishes. 2. The study of cadmium effect on the growth of Brassica napus embryo in Hogland food solution and the selection of B. napus types which are sensitive and resistant to cadmium chloride. 3. The effect of cadmium chloride is considered in respect of these aspects: Variation in amount of chlorophyll from leaves. 4. The study of role of cadmium in roots and aerial parts of the plant. 5. The study of amount of cadmium in the seeds due to green house cultivation of two sensitive and resistant varities Brassica napus kinds. %0 - Journal Article %I - %@ - 0125-895
