Effect of auxin type on some antioxidative enzymes during in vitro root induction of saffron (Crocus sativus L.) was investigated to reveal the variation of activities and isoenzyme banding patterns during root induction of saffron (C. sativus L.). Indole-3- butyric acid (IBA) and naphtalene acetic acid (NAA) at different concentrations were added to the solidified MS or B5 medium. Corm explants of saffron were placed on root inducing media and enzyme levels in explants prior or after adventitious root formation were measured and compared. Percentage of root formation on B5 medium containing 2.46 ìM IBA was highest; however the maximum number of root per explant and per cm2 observed on MS medium with 19.6 ìM IBA. Significant changes occurred in the activities of these enzymes. Some polymorphisms occurred in patterns of lactate dehydrogenase and esterase during root induction in different treatments.
