Effects of Crude Oil Contaminated Soil on Biomass Accumulation in Jatropha curcas L. Seedlings

A study was conducted in 2010 to investigate the effects of crude oil contaminated soil on biomass accumulation inJatropha curcas seedlings in Asaba, Delta State, Nigeria. Oil levels used were 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0% w/w. The trial was arranged in a randomized complete block design with four replications and monitored for 12 weeks after transplanting. Results showed that contamination...

Phytoremediation of soil contaminated with used lubricating oil using Jatropha curcas.

Soil contamination by used lubricating oil from automobiles is a growing concern in many countries, especially in Asian and African continents. Phytoremediation of this polluted soil with non-edible plant like Jatropha curcas offers an environmental friendly and cost-effective method for remediating the polluted soil. In this study, phytoremediation of soil contaminated with 2.5 and 1% (w/w) wa...

Detoxification experiments with the seed oil from Jatropha curcas L

Due to its large number of potential utilizations Jatropha curcas L. (physic nut, purging nut), a tropical plant cultivated in many Latin American, Asian and African countries, has become topic of various research projects. Nutritional as well as technical applications, however, are restricted due to the plant’s toxicity. The seed oil contains phorbol esters, a family of compounds known to caus...

Effects of salt stress on growth, antioxidant enzyme and phenylalanine ammonia-lyase activities in Jatropha curcas L. seedlings

The effects of increasing NaCl concentrations on biomass, superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and phenylalanine ammonia-lyase (PAL) in Jatropha curcas L. seedlings were investigated. The fresh weights of cotyledons and radicles with increasing NaCl concentrations decreased progressively, and the fresh weight of hypocotyls reached the lowest level at NaCl concentration ...

Growth of seashore paspalum, (Paspalum vaginatum L) in soil contaminated with crude petroleum oil

The effect of crude oil contaminated soil on the growth of seashore Paspalum ( Paspalum vaginatum .) seedlings was investigated. Plants were grown in soil containing different concentrations: 0%, 0.5%, 1.0%, 2.0% and 3% (w/w) of Abura crude petroleum oil. Growth parameter such as shoot number, shoot length, leaf area and biomass accumulation were evaluated. The results showed that crude oil imp...
