- Association Increasing diesel concentration was negatively correlated with biomass, stem and root length, leaf number and chlorophyll in Lactuca sativa.
- Association Increasing diesel concentration was negatively correlated with biomass, stem and root length, leaf number and chlorophyll in Ipomoea batatas.
- Observation The diesel concentration associated with a 10% growth decrease was 0.33 ml for lettuce.
- Observation The diesel concentration associated with a 10% growth decrease was 1.50 ml for sweet potato.
- Observation Lettuce growth was more sensitive to diesel contamination than sweet potato.
- Observation Root and shoot dry matter partitioning patterns were similar in both plants.
- Observation At 0-6 ml diesel contamination, shoot allocation was favoured and lettuce shoot:root ratio was 4.54.
- Observation At 0-6 ml diesel contamination, shoot allocation was favoured and sweet potato shoot:root ratio was 12.91.
- Observation Lettuce accumulated more metals in tissue than sweet potato.
- Observation Tissue mineral nutrients varied little in lettuce and sweet potato.
- Mechanism Authors attributed poor growth and mortality to hydrocarbons in diesel.
