Influence of thidiazuron and sucrose on enzyme activity and postharvest longevity of two rose cut flowers
چکيده


Abstract One of the main problems in rose cut flowers, is a short postharvest life. For the study of thidiazuron and sucrose on enzyme activity and vase life of two rose cut flowers, the expriment as a factorial on based completely randomized design with three replications and each replication consisted of three cut flowers was conducted in postharvest Lab. Factors include two cultivars of roses ‘High Magic’ and ‘Nablus’, thidiazuron (TDZ) at three levels (٠, ٣٠ and ٦٠ μmol) and sucrose at three levels (٠, ١ and ١٫٥ percent). The results showed that the concentration of ٦٠ μmol thidiazuron has greatest influence on survival, flower diameter, leaf and petal relative water content (RWC), catalase and peroxidase activity in two cultivars.Control and ١٪ sucrose had the least effect on survival of flowers. Overall, we can say that thidiazuron more effective than sucrose concentration, so it is useful to extend the vase life of rose cut flowers.
