“…Also, showed that the vase life of lisianthuses was significantly extended with the application of 2 mM SA, but when SA was applied at the rate of 4 mM, the vase life was shortened. Moreover, Cavasini et al (2015) found that a dose of 1000 mg L -1 of SA was detrimental to the vase life of cut lisianthus. The negative effect of high levels of SA on the vase life and related traits has also reported for cut carnation and chrysanthemum (Mansouri, 2012), which is consistent with our findings.…”

Lisianthus is a major cut flower, but it has a short vase life. To prolong postharvest longevity and improve quantitative and qualitative traits of cut lisianthus flowers, an experiment was conducted on the basis of a Completely Randomized Design with eight treatments on 120 flower sprays in three replications. The experimental treatments included salicylic acid (SA) at the rates of 50, 100 and 200 mg L-1, cerium nitrate [Ce(NO3)3] at the rates of 20, 40, 80, and 200 μM, and control (distilled water). The results revealed that the flowers treated with 40 μM Ce(NO3)3 and those treated with 100 mg L-1 SA had the longest vase life of 15.42 and 15.20 days, respectively. Also, these treatments were most effective in improving water uptake, reducing microbial load at the stem end, and enhancing petals’ protein content. The lowest malondialdehyde (18.65 nmol g-1fresh weight) was related to the treatment of 40 μM Ce(NO3)3 and 100 mg L-1 SA. These treatments showed the lowest polyphenol oxidase (PPO) activity, too. The activity of ascorbate peroxidase (APX) and peroxidase (POD) antioxidant enzymes was significantly higher in the flowers treated with 40 μM Ce(NO3)3 and 100 mg L-1 SA. The treatment of 200 mg L-1 SA had negative effects on all the recorded traits. So, it can be concluded that the treatment of cut lisianthus flowers with 40 μM Ce(NO3)3 and 100 mg L-1 SA can prolong their postharvest longevity by reducing lipid peroxidation and increasing the activity of antioxidant enzymes.

The demand for flowers and ornamental plants has significantly increased in recent years. However, in most cases, the production of such species is accompanied by inappropriate postharvest handling, which is responsible for significant losses of marketed flowers. Lilium pumilum, a member of the family Liliaceae, is one of the ornamental species with economic potential as potted or cut flower, which features long stalks containing orange inflorescences with several flower buds and numerous smooth as well as linear leaves. Due the high perishability of this product, appropriate techniques that extend flower longevity should be employed. The present study was developed to evaluate the effect of salicylic acid (SA) on the postharvest preservation of L. pumilum inflorescences. Stalks were kept in maintenance solution with different concentrations of SA (0, 1, 5 and 10 mM) for 0, 6, 12, 18 and 24 h. The L. pumilum flowers had longevity decreased by 57.8 and 63.1% when kept in 5 and 10 mM SA, respectively, compared with control. This effect may be associated with the observed decrease in the percentages of flower opening and chlorophyll content as well as the damping-off of stalks, indicating phytotoxicity. Therefore, the use of 5 and 10 mM SA is inefficient to extend the longevity of L. pumilum.
