Phenolic (vanillic, p-coumaric, ferulic and p-hydroxybenzoic) acids inhibited corn seedling radicle elongation in bioassay studies, especially at solution concentrations exceeding 1.0 × 10−4M. Radicle growth inhibition among hybrids was different when p-coumaric or ferulic acids were assayed, suggesting that corn sensitivity to phenolic acid phytotoxicity may be hybrid dependent. Key words: Allelopathy, phenolic acids, radicle growth inhibition, corn, Zea mays L., hybrid response

Sites co-contaminated with organic and metal pollutants are common and considered to be a more complex problem, as the two components often have a synergistic effect on cytotoxicity. This study investigated the dissipation mechnisms for pyrene in cadmium co-contaminated soil in which maize (ZEA MAYS L.) was grown in a greenhouse experiment. Results showed the growth response of maize may be affected by the co-contamination due to the interaction between the heavy metal and organic pollutants. Pyrene in both planted and unplanted soil diminished significantly at the end of 60-day culture, accounting for 21-31% of the initial extractable concentration in unplanted soil and 12-27% in planted soil, which indicated that the dissipation of pyrene was enhanced by the presence of vegetation. Although the presence of cadmium stimulated the accumulation of pyrene in roots and shoots of maize, contributions of plant off-take of pyrene to the total remediation enhancement in the presence of vegetation was less than 0.3%. A significant positive correlation was observed between soil enzyme activities (dehydrogenase, polyphenol oxidase) and the removal ratio of pyrene. Plant root exudates appear to promote the number of rhizosphere microorganisms and enzyme activity, thereby improving biodegradation of pyrene.
