| Aluminum (Al3+) toxicity is one of the major factors that limit plant growth and crop yield in acid soils. The phytotoxic effects of aluminum on seed germination and initial growth of physic nut (Jatropha curcas L.) seedlings were investigated in the present study. Physic nut seeds were subjected to five levels of aluminum [0 (control), 20, 40, 60 and 80 mg L–1], using the solution-paper method, with eight replications. The experimental unit consisted in a germitest paper roll with 25 physic nut seeds.Treatments were evaluated based on the following tests: first count of germination test (7 days), total germination (12 days) and initial growth of physic nut seedlings (12 days). The addition of 80 mg L–1of Al reduced the first count of germination test... |
