Abstract :Brassinosteroids insert ignore into journalissuearticles values(BRs); are steroid phyotohormones that play roles in plant growth, secondary metabolite accumulation, stress response, and adaptation. Saffron insert ignore into journalissuearticles values(Crocus sativus L.); is an important plant with significant pharmacological effects due to its rich phytochemical content. Crocin, the main pigment of the saffron stigma, is a natural food colorant and has anti-cancer activity. In this study, the effects of 24-Epibrassinolide insert ignore into journalissuearticles values(EBL); at different concentrations insert ignore into journalissuearticles values(10-6, 10-7, 10-8 and 10-9 M); on corm insert ignore into journalissuearticles values(mother corm); and aerial part related parameters as well as the level of crocin in saffron were investigated. The experiment was conducted in a plant growth cabinet as randomized plots design with 3 replications. 24-Epibrassinolide treatments did not affect the rates of shoot emergence from saffron corms, while 10-8 and 10-9 M EBL treatments increased the number of active nodium and cormlet insert ignore into journalissuearticles values(daughter corm); as compared to control. All the applied EBL concentrations significantly increased the root and shoot lengths of saffron plants. The maximum number of flowers per plant was observed as a result of the 10-8 M EBL treatment. Exogenous treatment of 10-9 M EBL enhanced the crocin level by 96.0% compared to the control. This is the first study to evaluate the effects of BRs in saffron.
