“…In this study, MeJA treatment was more effective for prolonging the vase life of foxtail lily as compared to salicylic acid application. In agreement with these results, the effectiveness of SA and spermine was varied on prolonging of vase life of cut alstroemeria flowers (Langroudi et al, 2020). Also, in the research of Hemati et al (2019), SA was more effective on prolonged the day to bent stem in gerbera cut flowers as compared with MeJA.…”

“…In this study, SA treatments, especially in 200 mgL -1 concentrations, significantly prolonged the vase life of cut foxtail lily inflorescences as compared to control. In agreement with these results, several previous studies reported that pre or post-harvest exogenous application of salicylic acid (SA) delayed considerably senescence and prolonged the vase life of different cut flowers such as rose, alstroemeria, and chrysanthemum (Mansouri, 2012;Kazemi et al, 2018;Langroudi et al, 2020).…”

“…However, most of these commercial agents still have some disadvantages, such as no ideal effect, poor stability, environmental pollution and toxicity (Li et al, 2017). In this context, nanosilver (NS), due to strong antibacterial activity and wide activity spectrum and safety, recently gained attention as a promising antimicrobial agent (Li et al, 2017;Langroudi et al, 2020).…”

Eremurus spectabilis is a new, commercially valuable specialty cut flower, but little is known about the applicable treatments to extend the vase-life and maintaining the ornamental quality of this flower. Therefore, the present study was aimed at investigating the impacts of nano-silver, essential oils, and chemical treatments on keeping ornamental quality and vase-life of cut inflorescences of Foxtail lily. The cut inflorescences were placed in different vase solutions containing salicylic acid (100 and 200 mg L-1), methyl jasmonate (25 and 50 mg L-1), silver thiosulfate (0.1 mM) plus isothiazolinone (0.001 and 0.005 mL L-1), nano-silver (5, 10, and 15 mg L-1), thymol (75 and 120 mg L-1), and menthol (75 and 120 mg L-1), which were applied as continuous and pulsing methods. According to the results, all treatments considerably improved the post-harvest performance of Foxtail lily cut flowers. Although there were no significant differences among nano-silver (NS) treatments, the cut inflorescences kept in vase solution containing 10 mg L-1 of NS exhibited the longest vase life (~14 days) and the best ornamental quality. Nano-silver treatment followed by silver-thiosulfate significantly improved solution uptake by flowering inflorescences, thereby delaying the water balance loss and keeping relative fresh weight. Furthermore, 50 mg L-1 methyl jasmonate- and 75 mg L-1 menthol-treated cut inflorescences exhibited significantly higher vase-life longevity by ~ 6 and 4 days, total soluble solutes by 28.38% and 19.12%, and solution uptake rate by 76.46% and 140.6%, respectively, as compared to control. Overall, 10 mg L-1 NS can be recommended as a commercial preservative solution to delay flower senescence and improve the vase life and keeping the quality of foxtail cut inflorescence.

“…The mechanism of action of silver in nanoparticles is not completely understood and only partial explanations of its mode of action in cut flowers have been published 17,18 . There are numerous reports that it prolongs the flower vase life 7,[14][15][16][17][18] . Here, in cosmos, it also increased flower longevity, by as much as 50% relative to water, but its effect was not statistically different from that of the 8-HQC.…”

To prolong their vase life, cut flowers are commonly kept in holding solutions. These must include a biocide to retard bacterial growth. In this study, the effect of nanosilver (NS) on certain aspects of senescence in cut garden cosmos (Cosmos bipinnatus) flowers was compared to that of the commonly used 8-hydroxyquinoline citrate (8-HQC). In combination with sucrose, both biocides prolonged cosmos vase life but did not prevent the occurrence of stem blockages. NS was more effective in limiting a reduction in endogenous soluble carbohydrates. The malondialdehyde (MDA) contents increased in senescing ray florets, both in intact and control cut flowers held in water. Both biocides were comparably effective in limiting this effect. The hydrogen peroxide content tripled in intact flowers but dropped in flowers held in water or the 8-HQC solutions; in flowers kept in NS solutions its increase was moderate. Also, the catalase activity increased in intact flowers but dropped in all cut flowers. Both biocides had similar effects on the enzyme activity, in both pure solutions and with sucrose. Most of these parameters were not significantly correlated with vase life. Overall, the effect of nanosilver on senescence in cut cosmos flowers was similar to that of 8-HQC. Growing consumer interest in new cut flower species drives field production of seasonal, locally grown flowers 1. Garden cosmos-also known as lace cosmos because of its delicate pinnate foliage-is gaining popularity not only as a garden or a bedding plant but also as cut flowers. Diversity of forms and colors make the species popular among florists and customers but its postharvest longevity is short, usually 4-6 days 1. However, this longevity can be doubled by making use of the so-called flower food, i.e. holding solutions containing a biocide and a sugar 2. These two components are crucial in extending the vase life as they delay flower senescence. Senescence usually occurs faster in cut flowers than in those left on mother plants. This was clearly illustrated by de Stigter 3 on cut and intact hydroponically grown 'Sonia' roses observed under the same environmental conditions and confirmed by subsequent studies on rose 4 , lilac 5 , clematis 6 and peony 7. The processes of senescence are accelerated mainly by water stress caused by improper water balance in cut stems. Such stems, even when held in water, are unable to absorb sufficient amounts of water to compensate for the transpiration losses. Vessels in cut stems become obstructed by blockages of various nature, with the presence of microbes in vase water being the most common 8. For this reason, biocides in holding solutions are crucial for the postharvest longevity of cut flowers. For over a half a century the esters of 8-hydroxyquinoline have been used as potent biocides, in mixtures with sucrose. This is called the standard preservative 9. Nanosilver [NS] has emerged as a new biocide for cut flowers after the use of toxic silver nitrate had been outlawed 10. Though it was enthusiastically accepted in ...

“…The use of AgNPs in agricultural and horticultural fields has recently increased due to their contribution to plants physiological improvements (Byczyńska, 2017a). The positive effects of AgNPs increased vase life in cut alstroemeria (Alstroemeria 'Summer Sky') (Langroudi et al, 2020), extended post-harvest life of cut 'White Parrot' Tulipa flowers (Byczyńska, 2017b), supported growth and enhancement of inflorescences in Carthamus tinctorius (Zari et al, 2015). AgNPs treatment by decreasing stem blockages delays the senescence of cut Antirrhinum flowers (Rabiza-Świder, 2020).…”

The use of silver nanoparticles (AgNPs) in the fields of agriculture and horticulture has been increasing recently due to contribution to seed germination, plant growth and development, flowering, yield, and physiological improvements. This research aimed to investigate the effects of silver nanoparticles on the growth and flowering characteristics of the 'Santander' lily (Lilium L.) variety and to determine its potential for use in cultivation. Before planting the plant bulbs immersed in AgNPs solutions of 0 (control), 50, 75, 100, 125 and 150 ppm. After harvest; weight, circumference, height, root length, fresh and dry weight, stem root length, fresh and dry weight of stem, plant height, plant stem diameter, fresh plant weight, bud number and vase life were determined. As a result; it has been indicated that AgNPs solutions in different concentrations increased the quality and quantity of cut flowers and bulbs in lily plants. AgNPs increased an average of 26.29% when compared with control in all morphological characteristics except for the vase life. In the light of these findings, AgNPs applications can be preferred as a method that can be used on lily cultivation and reproduction. Nevertheless, considering the deficiency of treatments of AgNPs in lily plants and their poorly known effect on plants, further detailed studies are necessary.
