| Cucurbita pepo | the treatment of 5-day-old cotyledons with different concentrations of each of indole-3-acetic acid, indole butyric acid, indole propionic acid and naphthalene acetic acid results in a significant increase in the urease activity, compared to control. Indole-3-acetic acid is the most effective in stimulating urease activity. Optimal urease activity is observed in cotyledons subjected to 0.5 mM indole-3-acetic acid, it is about 3.5fold higher than the control. A gradual increase in urease activity is detected in cotyledons treated with various concentrations (0.2-1.0 mM) of 28-homobrassinolide, in relative to control. A substantial increase in urease activity is observed in cotyledons subjected to different concentrations of triazole (10-60 mg/l), containing either triadimefon or hexaconazole, compared to control | up |
