【 摘 要 】

The presence of the heavy metals toxic compounds (CuSO4• 5H2O, ZnSO4• 7H2O and 3CdSO4•8H2O) in water and soil can be observed by their negative effects on the germination and growth process for different vegetable (barley, oat, maize) who are used for human and animal consumption. This paper it aims the determination of germination and growth inhibition negative effects for triticale plants in the heavy metals ions presence by ecotoxicological laboratory tests. The triticale plants was chosen for their different characteristics to the other grasses respectively: a very good resistance for a wide range of diseases, an accelerated growth and a very good tolerance for aluminum ions presents in acid soils. The determinations were conducted step by step, first, we put the triticale grains in contact with the heavy metal solutions with different concentration then for 3 days we noticed the triticale germination inhibition effects and finally we noticed the growth inhibition process for triticale plants respectively in 7thand 9thday from the start of the experiment. At the end of the tests we can conclude that the triticale roots have a very great sensibility to a CuSO4solutions compared to the effects for their stalks. A positive effect for triticale stalks we can see for low CuSO4solution concentrations thus for 5 mg Cu/l the growth is 19,44%. A positive effect for triticale roots it can see for low ZnSO4solution concentrations so for 5 - 15 mg Zn/l the growth is 24,4%. In the presence of the CdSO4solution all the processes are inhibited (germination and growth for triticale plants) even for a low concentrations for this toxic.
