Özet

Objective: The growth of plants during recovery period after freezing stress is more important for winter cereals to survive frost. However, little research has been done on physio-biochemical changes in response to recovery or rewarming conditions in cereals. In this study, the changes in oxidative stress intensities and antioxidant enzyme activities were thus examined under cold acclimation (CA), short-term freezing stress (F) and rewarming (R) conditions in barley cultivars differing in cold tolerance in order to assess the changes in Reactive Oxygen Species (ROS) scavenging system.
