The enzymatic and non-enzymatic antioxidant responses and the levels of some reactive oxygen species in leaves were measured. <strong>Results:</strong> The high ascorbate content and high ascorbate peroxidase activity found in some almond species contributed to the decrease in H<sub>2</sub>O<sub>2</sub>. Generally, catalase activity increased after the cold treatments, whereas superoxide dismutase activity and OH• levels varied markedly among the species.<strong> Conclusions:</strong> The differences in antioxidative traits among the almond species support the hypothesis of their importance in cold tolerance and could provide an useful probe to identify tolerant genotypes in breeding programs.</p>}, number={1}, journal={Free Radicals and Antioxidants}, author={Adriano Sofo and Shakiba Rajabpoor and Hamid Yaghini and Maryam Shirani and Azin Archangi and Seyed Ehsan Sangi and Farahnaz Tavakoli and Mehdi Khodai and Karim Sorkheh}, year={2014}, month={Feb.}, pages={70–74} }
