Özet

Under field conditions, growth parametres like fresh weight and leaf number, superoxide dismutase (SOD), catalase (CAT), ascorbic peroxidase (APX) enzymes in the antioxidant defence sytems are analysed on 12 lines and two cultivars of pea seedlings which are specified as tolerant against cold. Besides the relationship between the protection mechanisms from abiotic stress conditions (change on the antioxidant enzymes) on the pea plant is tried to be revealed. In terms of macro and microelement accumulation, considering control plants, the effect of low temperature application is not observed in Mn, Mg, Cu microelements. However, approximately ten times decrease is observed on Fe and Zn accumulations. It is also observed that there is not a change on K and Ca accumulation of the plants considering control plants. It is seen that with the low temperature application, there are significant increases on CAT, APX and SOD enzyme activities which are among the antioxidant enzymes of the plants.
