چکیده مقاله:
In this research, the effect of different concentrations of Nickel (0, 1.5 and 2.5 mM), Salicylic acid (0, 1 and 2 mM), Cobalt (0, 1 and 2 mM) and sucrose (0, 2.5%) on flower longevity, Acc-oxidase activity,anthocyanin leakage, microbial population, water uptake and SPAD value as a measure of leaf greenness of Lilywas investigated. To evaluate the effect of these treatments, a study was carried out based on the randomizedcomplete design with five replications. Results of this experiment showed that the best treatment in extending the longevity of the flowers were solutions containing 2 mM SA, 2 mM SA+ 2.5% sucrose and 2.5mM Ni+ 2 mM SA+2 mM Co with 2.5% sucrose. SA, Ni and Co decreased the anthocyanin leakage, whereas the highest concentrations of SA, Ni and Co reduced ACC-oxidase activity. The Maximum of chlorophyll content was observed for flower kept in solution containing 2 mM SA and 2 mM SA+ 2.5% sucrose compared to the control and solution containing Ni and Co. Ni and Co treatments had no positive effect on increasing the water uptake and fresh weight of Lily. Overall, the results suggest that SA, Ni, CO and sucrose increase the vase-life by improving the membrane stability and reducing the oxidative stress damages during Lily flower senescence
