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.

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.

Conservation systems of production are promoting yields and profitability, intercropping systems aim at sustainable maximization of soil and water use, and have become an alternative for regions characterized by relatively short rainy periods and high temperatures. The objective of this work was to evaluate the influence of the intercropping system between maize (Zea mays L.) and C. juncea (Crotalaria juncea L.) on soil temperature and humidity for the municipality of Tangará da Serra in Brazil. The treatments consisted of the single crop of maize and crotalaria, as well as their intercrop cultivation, the soil temperature was evaluated at depths of 0.10, 0.20, 0.30 and 0.40 m and soil moisture at depths of 0.20 and 0.40 m. The components of grain production and yield of maize were also evaluated, for crotalaria, height, diameter and dry mass of the plants were evaluated. The highest soil temperature occurred at 14 h with an average of 21°C for all three treatments. The intercropping of maize with crotalaria gave the soil a lower amplitude of the soil temperature and kept the soil moisture high with values of 0.3 m3 m-3 in the depth of 0.20 m. The development stage presented the lowest mean thermal amplitude and higher humidity for the intercrop system. The yield of maize in an intercrop was reduced by 42.7% compared to a single crop.
