Perioxidases play important roles in abscisic acid (ABA)-simulating photosystem II (PSII) thermostabilty of apple tree rootstock leaves
Original language description
Leaf photosynthetic activity limited by summer heat stress represents large constraint to production process of fruit trees. To cope with this problem, we tested photosystem II (PS II) thermostability in clonal apple tree rootstocks with different growthintensity - semi-vigorous-MM106 and dwarfing-J-TE-F experiencing summer heat stress, and related antioxidative activity and phytohormonal balance. The expanded leaves were collected and utilized for determination of 3-indoleacetic acid (IAA), cytokinins(CKs), abscisic acid (ABA) concentrations, and superoxide dismutase (SOD), total peroxidases (POX), catalase (CAT), total antioxidative activity (TAA) and PS II thermostability before and after 30 min dark exposition to temperature of 42°C. We can conclude that in PS II heat-hardening of apple tree rootstock leaves, which is at least partly provided by enhanced peroxidases activity, ABA plays the central role and J-TE-F rootstock can be recomended to heat stress in the prone regions.
