Chilling stress is an abiotic stress including meteorological dynamics that happens at low temperatures. Chilling stress was introduced as the most important limiting factor in tropical and subtropical plants. In antioxidant activity, catalase, malon di-aldehyde and peroxidase enzymes were treated at temperatures of 20 ° C (control), zero degrees and 5 ° C in three Thymus vulgaris, Thymus daensis and Thymus kotschyanus thyme cultivars. The composite analysis was carried out with 3 replications. The results showed that there was a significant variation among the Thymus cultivars in terms of how to respond to temperature stresses, and the rate of enzyme changes in each of 3 significant factors justifying the role protecting them against environmental changes. Only in the amount of activity of catalase activity, the interaction of cultivars with treated temperatures was not particularly significant at 20 ° C (control) and zero degree, indicating the equality of the mode of reaction of thyme cultivars to the two treated temperatures.
