title: Changes in antioxidant enzymes activities and proline, total phenol and anthocyanine contents in Hyssopus officinalis L. plants under salt stress.
abstract: The relationships between salt stress and antioxidant enzymes activities, proline, phenol and anthocyanine contents in Hyssopus officinalis L. plants in growth stage were investigated. The plants were subjected to five levels of saline irrigation water, 0.37 (tap water as control) with 2, 4, 6, 8 and 10 dSm(-1) of saline water. After two months the uniform plants were harvested for experimental analysis. Antioxidant enzymes activities and proline, phenol and anthocyanine contents of the plants were examinated. Enhanced activities of peroxidase, catalase and superoxide dismutase were determined by increasing salinity that plays an important protective role in the ROS-scavenging process. Proline, phenol and anthocyanine contents increased significantly with increasing salinity. These results suggest that salinity tolerance of Hyssopus officinalis plants might be closely related with the increased capacity of antioxidative system to scavenge reactive oxygen species and with the accumulation of osmoprotectant proline, phenol and anthocyanine contents under salinity conditions.
