Cadmium induced oxidative stress and its interrelationships with physiological characteristics in wild and cultivated species of safflower Nasibeh Pourghasemian Najafabadi E mail address n poorghasemian@ag iut ac ir Date of submission January 2013 Department of Agronomy Plant Breeding College of Agriculture Isfahan University of Technology Isfahan 84156 83111 Iran Parviz Ehsanzadeh ehsanp@cc iut ac ir Morteza Zahedi Hossien Shariatmadari College Graduate Program Coordinator Mehdi Majidi Assoc Prof and Assist Prof respectively Department of Agronomy Plant Breeding College of Agriculture Isfahan University of Technology Isfahan Iran Prof Department of Soil Science College of Agriculture Isfahan University of Technology Isfahan Iran Abstract In order to study the cadmium induced oxidative stress and its interrelations with different physiological characteristics of cultivated Arak 2811 Saffire C111 and AC Sterling and wild safflower Arak Shiraz Isfahan and Azari genotypes as well as absorption and translocation of and tolerance to cadmium Cd under different temperatures four experiments were conducted Results of the first and second experiments indicated that Cd translocation from roots to the shoots for the cultivated safflower genotypes was greater than for the wild genotypes Among the cultivated and wild genotypes AC Sterling and Arak were defined as the tolerant and non tolerant genotypes to the Cd stress respectively An increase in temperature from 18 to 23 C led to increases in Cd absorption translocation from roots to the shoots and negative impact on safflower tolerance for all genotypes except for the AC Sterling According to the results of the third experiment the greatest root and shoot Cd concentrations were found in the Saffire and the smallest in the AC Sterling The greatest Cd translocation from roots to the shoots was observed in AC Sterling At the 1 m level of CdCl2 the greatest and smallest amounts of cell wall bound Cd were found with AC Sterling and Arak respectively Maximum superoxide dismutase SOD activities at the roots and shoots for Saffire and Arak were observed at the 1 m and for Ac Sterling at the 20 m levels of Cd No significant differences were found between the safflower genotypes for the root cation exchange capacity CEC and in the suberization associated with the casparian band in the roots According to the results of the fourth experiment Ac Sterling Isfahan and Arak 2811 were ranked tolerant to the Cd stress The greatest activities of ascorbate peroxidase APX and catalase CAT were observed to be at the 5 mgkg 1 level of the Cd contamination The tolerant genotypes indicated a greater increase in their APX and CAT activity compared to the non tolerant genotypes The non tolerant genotypes appeared to have a greater activity of glutation reductase GR compared to the tolerant genotypes Key words cultivated safflower wild safflower cadmium antioxidative activity
