Changes in the activities of oxidative enzymes (indole acetic acid oxidase, peroxidase and catalase), endogenous hormones (gibberellic acid (GA3), indole acetic acid (IAA), abscisic acid (ABA) and cytokinins (AsZeatin), photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids), total carbohydrates, total soluble sugars, amino acid proline and vegetative growth parameters were used as indicators to explain the physiological role of the growth retardant prohexadione-calcium on Vicia faba seedlings 40 days after sowing under salinity stress for 30 days. The obtained results show that soaking faba bean seeds prior to sowing at different concentrations of prohexadione-calcium (0, 10, 20 and 30 ppm) significantly increased the activities of indole... |

This research aimed to evaluate the potential of several native white rot fungi (WRF) isolated from subtropical environments of Misiones (Argentina) to produce different ligninolytic enzymes. Coriolus versicolor f. antarcticus BAFC 266, Pycnoporus sanguineus BAFC 2126 and Phlebia brevispora BAFC 633 showed the highest phenoloxidase activity. Ganoderma applanatum strain E, P. sanguineus BAFC 2126 and P. brevispora BAFC 633 revealed marked laccase and peroxidase activity. C. versicolor f. antarcticus, G. applanatum (strain A) and Trametes villosa, gave high positive reactions with 2,6-dimethoxyphenol oxidation at the lowest tested pH. C. versicolor f. antarcticus, G. applanatum strains D and F, T. elegans BAFC 2127and T. villosa, showed the highest manganese... |
