This study evaluated the response (seedling emergence) of
Pentaclethra macrophylla seeds 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,
