SEED GERMINATION AND SEEDLING GROWTH OF Zea mays UNDER VARIOUS CONCENTRATIONS OF COPPER
The objective of this work was to verify the effects of copper on the germination and growth of corn seedlings in substrate of paper for germination plus copper at concentrations of 0, 100, 200 and 300 mg/L, generating four different treatments. The evaluations were carried out on the fourth, fifth, sixth and seventh days after sowing, and copper affected the initial germination rate and root size, without having any influence on shoot size.
