EFFECTS OF SOME HEAVY METALS IN SOME MORPHO-PHYSIOLOGICAL PARAMETERS IN MAIZE SEEDLINGS

Nowadays the heavy-metal pollution of the soil is causing ever greater problems, exacerbated by the fact that the heavy metals accumulated in plants may, either directly or indirectly, find their way into animals and human beings. The experiment design was randomly with repetition. Prepared seeds are placed on the germinator for germination which was added 10 mL H...O. Cultivation lasted 15-20 days at temperature 25...C in vegetative room. During the experiment in growth period are prepared the concentrations of heavy metals (600 mL/1 Kg compost); for lead (Pb...): 200 ...M (T1), 400 ...M (T2) and 400 ...M (T3); for cadmium (Cd...): 60 ...M (T4), 120 ...M (T5) and 180 ...M (T6); for Mercury (Hg...): 33 ...M (T7), 66 ...M (T8) dhe 100 ...M (T9). From the research with different treatments with various genotype and heavy metals the differences in the content of chlorophyll effects and carotenoides was different and significantly higher at level of probability of LSD p = 0.01.
