The Effects of Aluminum and Cadmium Metals on Germination of Maize and Lentil Seeds

In this study; the effects of various concentrations of aluminium [(al(no_3)_3.9h_2o] and cadmium [cd(no_3)_2.4h_2o] on the germination of maize (zea mays l.) and lentil (lens culinaris medik cv. kafkas) seeds were invastigated. germination experiments were carried out at a constant temperature (20°c), in the dark and in an incubator for 7 days. when aluminum and cadmium, particularly cadmiumwere increased in the seed concentration, seed germination was inhibited and delayed for both species. lentil seeds were more sensitive to the metals than from maize. when radicle output compared with coleoptile output of mazie; radicle have been more sensitive to aluminum and cadmium. radicle and hypocotyl of lentil are affected by the same rate. fresh weights of the seedlings from the germinated seeds were also found to be decreased by two metals.
