Effect of Ni, CO, SA and Sucrose on Extending the Vase-Life of Lily Cut Flower
In this research was investigated 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 mea...

| Summary: | In this research was investigated 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 Lily. To evaluate the effect of these treatments was carried out a study based on randomized complete 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 anthocyanin leakage whereas the highest of 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 than control and solution containing Ni and Co. Ni and Co treatments had no positive effect on increasing Water uptake and fresh weight of Lily. Overall, the results suggest that SA, Ni, CO and sucrose increases vase life by improving the membrane stability and reducing oxidative stress damages during Lily flower senescence. |
