“…Salicylic acid, sodium nitroprusside and spermidine delay the senescence of owers by inducing the activity of antioxidants and strengthening the antioxidant system of cells and control the reduction of sugar and soluble protein. In con rmation of the results of this study, in relation to the effect of spermidine on the amount of protein and soluble sugar, studies have shown that polyamines increase the amount of photosynthetic pigments and carbohydrates in the plant, and decrease the protein hydrolysis of cut owers of lily, gerbera and carnation and delayed senescence (Amorim et al 2017;Vieira et al 2017). Research has also shown that salicylic acid increases protein levels in plants by preventing the destruction of cell structures and increases carbohydrate (Apostolova et al 2008).…”

“…Salicylic acid can reduce ROS with its antioxidant properties, and on the other hand, by reducing the activity of the lipoxygenase enzyme, it reduces the degradation of membrane lipids (Ershad Langroudi et al 2020). The positive effect of polyamines in reducing ion leakage of hydrogen peroxide and malondialdehyde with their ability to bind to membrane phospholipids and other membrane anion components can be explained by increasing the stability of the plant cell structure and inhibiting the activity of the lipoxygenase enzyme, preventing the lipid destruction of the membrane (Vieira et al 2017). Polyamines also prevent the activity of reactive oxygen species and free radicals with their antioxidant activity and increase the activity of antioxidant enzymes, thus reducing the amount of hydrogen peroxide and malondialdehyde in the cell (Kamiab and Zamanibahramabadi, 2016).…”

Post-harvest senescence is one of the crucial challenges limiting the commercialization of cut flowers. Long vase life is the most important factor determining the economic value of cut flowers. Major factors limiting the vase life of lisianthus cut flower included sensitivity to ethylene, inability to absorb water resulting in bending and suppression of bud opening and coloring, which must be considered at the post-harvest stage. Therefore, the present study was carried out to investigate three types of growth regulators, salicylic acid (SA), sodium nitroprusside (SNP) and spermidine (Sp), each with four concentrations and in four replicates, on the vase life and quality of Lisianthus cut flowers in post-harvest stage. The three regulators have a positive effect on the longevity of Lisianthus cut flowers and reduce ion leakage, malondialdehyde and hydrogen peroxide and increase the activity of the antioxidant enzymes, ascorbate peroxidase and guaiacol peroxidase, and preserving the degradation of lipid membrane and cell stability. The most appropriate concentrations in this study included 1- and 2-mM salicylic acid and/or spermidine as well as sodium nitroprusside concentrations of 40 and 60 µM.

The polyamines, putrescine, spermidine and spermine, are low-molecular weight substances, synthesized in eucariot cells from their immediate precursor, ornithine. The polyamines are found in fruits and vegetables, foods of animal origin and fermented food products. As plant growth regulators, are believed to be involved in several physiological processes. Gibberellins are plant hormones that regulate growth and influence various developmental processes and are derived via the ent-gibberellane skeleton. Gibberellins are synthesized by the terpenoid pathway in plastids and then modified in the endoplasmic reticulum and cytosol until they reach their biologically-active form. Here, we show the importance gibberellin and polyamines functions in plant growth, development, and postharvest senescence of various ornamental plants. Studies initiated on the application of the polyamines and gibberellins in ornamental plants should improve our knowledge in the future.

“…Moreover, decrease in membrane seepage due to polyamine application has also been found to be associated with flower longevity as reported in cut rose flowers (Ghorbani et al, 2018). Polyamine mediated increase in vase life has been also reported in Rosa hybrida, Nicotiana plumbaginifolia and Dianthus caryophyllus (Nisar et al, 2015;Vieira et al, 2017;Karimi et al, 2017). The floral diameter also registered an increase in polyamine treated spikes.…”

“…Generally, ethylene and polyamines have antagonistic roles in relation to flower senescence due to their competition for the common precursor, S-adenosyl methionine (SAM) (Davarynejad et al, 2021). Polyamines are purported as effective anti-senescence chemicals with convincing role in regulation of senescence as observed in Rosa and Gerbera (Vieira et al, 2017;Ghorbani et al, 2018). Polyamines improve vase life by reducing ethylene output, respiratory rate and color fading of petals (Tiburcio et al, 2014;Karimi et al, 2017).…”

Polyamines accentuate vase life by augmenting antioxidant system in cut spikes of Consolida ajacis (L.) Schur.

Postharvest senescence is one of the crucial challenges limiting the marketability of cut flowers. Pertinently, recent investigations implicate extensive role of polyamines in regulation of flower senescence. The present study was envisaged to test the efficacy of poylamines in preserving the postharvest quality of Consolida ajacis (C. ajacis) cut spikes. The cut spikes of C. ajacis were subjected to various treatments of polyamines viz, 4 mM Spermine (SPM), 6mM Putrescine (PUT) and 6 mM Spermidine (SPD). A separate set of spikes held in distilled water represented the control. Our results authenticate a significant improvement in vase life of cut spikes of C. ajacis as compared to control. The increment in vase life was commensurate with the higher concentration of sugars, proteins and phenols in the tepal tissues. Polyamines amplified the activity of various antioxidant enzymes viz, superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) to overcome the deleterious effects of reactive oxygen species (ROS). The membrane outflow of tepal tissues was profoundly reduced due to attenuated lipoxygenase (LOX) activity. These findings reveal conspicuous role of polyamines particularly SPM in modulation of flower senescence in cut spikes of C. ajacis.
