Abstract

This study evaluated the response (seedling emergence) of Pentaclethra macrophyllaseeds sown in soils contaminated with spent lubricating oil using 0, 1, 2, 4 and 8% w/w in Asaba, Delta State in 2009. The results showed that 100% of the seeds sown in the control germinated. Significant reductions (P ≥ 0.05) were however recorded in seeds planted in the soils treated with the spent lubricating oil. The effects being concentration dependent. The study has shown that spent lubricating oil has a highly significant (P ≤0.05) effect of reducing the germination percentage and rate of germination of P. macrophylla as well as increasing the days to germination of this multipurpose tree species.

Key words: Influence, spent lubricating oil, seedly emergence, Pentaclethra macrophylla.
