“…Positive effect of cytokinins on prolonging the vase life of cut Alstroemeria flowers has previously been demonstrated (MUTUI et al, 2001;CHAMANI et al, 2006;FERRANTE et al, 2009;HATAMZADEH et al, 2012). External treatment of cytokinins delays cut flowers senescence (LOUBAUD; VAN DOORN, 2004).…”

“…Some studies showed that cytokinins are able to retard chlorophyll degradation (FERRANTE et al, 2004). External applications of BA had been effective on retarding senescence of various cut flowers by arresting degradation of protein and chlorophyll (MUTUI et al, 2001;HATAMZADEH et al, 2012). The data on chlorophyll content showed the positive role of CHI, coconut water and BA on preserving the leaves by lowering the percent of weight loss and inhibiting the chlorophyll degradation.…”

“…Results obtained by HATAMZADEH et al, (2012) showed that the pulse treatment of cut Alstroemeria flowers with 10 µM TDZ (a cytokinin-like PGR) delayed petal abscission (3.3 days) and leaf yellowing (25.7 days) compared to the untreated flowers. External application of BA had been effective on delaying senescence of various cut flowers by arresting degradation of protein and chlorophyll (MUTUI et al, 2001). BA effectively increased the vase life of cut Anthurium flowers (PAULL; CHANTRACHIT, 2001;FERRANTE et al, 2009).…”

“…Cytokinins KIN and BAP markedly delayed senescence and prolonged longevity and flower quality in CHI sprayed cut Hemerocallis fulva flowers (GULZAR et al, 2005). Cytokinins treatment delay leaf senescence and improve the keeping quality of many cut flowers (EMONGOR et al, 2000;MUTUI et al, 2001). HASSANPOUR; KARIMI (2010) showed that BA extended the vase life of cut Eustoma grandiflora flowers at all concentrations.…”

“…Senescence of many flowers is coordinated by a rise in ethylene biosynthesis (HASSANPOUR; KARIMI, 2010). Pulse treatment with cytokinins like BA delayed ethylene production and extended the vase life of cut Alstroemeria flowers and some other flowers (MUTUI et al, 2001). Also, BA could delay the change in fresh weight, respiration rate and water uptake (KITTISIRIPAT; TECHAWONGSTIEN, 2007;HATAMZADEH et al, 2012).…”

Early leaf yellowing in cut alstroemeria (Alstroemeria aurantiaca) flowers before flower development and petal abscission is an important limiting postharvest quality and vase life factors. Early leaf senescence reduces postharvest longevity of cut flowers and promotes petal's wilting. A study was made to evaluate the response of cut alstroemeria flowers at varying concentrations of cycloheximide (CHI) (50, 100 and 200 mg l -1 ), coconut water (5, 10 and 20%) and 6-benzyladenine (BA) (50, 100 and 200 mg l -1 ). CHI, coconut water and BA extended the vase life at all concentrations compared to the control, but coconut water at 5% concentration (with 17.39 days) was the most effective treatment. Control cut flowers showed the least vase life (10.76 days). Ethylene production in cut flowers promoted flower senescence. All concentrations of CHI, coconut water and BA delayed ethylene production compared to the control. Treatment of cut flowers with coconut water at concentration of 5% maintained the highest fresh weight of flowers and increased the content of water uptake. The chlorophyll degradation was significantly reduced by the application of CHI, coconut water and BA. The maximum content of membrane's lipid peroxidation and antioxidant enzymes activity (super oxide dismutase and peroxidase) was obtained in control cut flowers. Thus, 5% fresh coconut water has the potential to be applied as vase solution (preservative medium) due to prolongs of cut alstroemeria flowers.

Leaf yellowing is the major postharvest crisis for cut alstroemeria flowers. Most studies have focused on hormone application to overcome this problem, while other important aspects of postharvest treatment such as vase solution microbial contamination and biocide effects have been ignored. Therefore, this study aims at evaluating the vase life and physiological performance of 'Vanilla' alstroemeria cut flowers in response to biocide application and microbial flora during postharvest handling. During two experiments flowers were treated with environmentally friendly and safe to use biocides such as citric acid (as acidifying agent) and sodium hypochlorite (as chlorination agent). Subsequently postharvest physiological parameters, namely vase life, side effect, weight change, solution uptake, chlorophyll content, and microbiological features of the vase solution such as microbial population, proliferation, and composition were studied. The results of the physiological study indicated a beneficial effect of chlorination on the vase life and most physiological parameters, especially chlorophyll content, and consequently, the green appearance of the leaves. Vase solution acidification, however, did not have a long lasting beneficial effect on physiological properties. Furthermore, microbiological studies show the efficacy of chlorination in reducing the vase solution microbial population and proliferation. By contrast, the vase solution acidification with citric acid was not able to control microbial proliferation. Microbial identification indicated Bacillus bacterial contamination as the dominant microbial vase solution flora.

The rapid yellowing of the leaves on cut flowers with leafy stems severely limits their vase life and commercial value. In this study, the effect of a composite of multi-walled carbon nanotubes (MWCNTs) and polyvinyl pyrrolidone (PVP) on the longevity of cut Alstroemeria flowers (Alstroemeria hybrida) was investigated to obtain a solution to this problem. A range of MWCNTs/PVP composite concentrations (0, 3, 6, and 9 mg L−1) was applied in a vase solution (for 24 h) as pulse treatments. Our findings indicate that the composite of MWCNTs and PVP exhibits excellent dispersibility in a vase solution. The results demonstrate that a 3 mg L−1 MWCNTs/PVP concentration was the most effective, extending the vase life of cut Alstroemeria flowers by up to 27 days. Pulsing with MWCNTs/PVP delayed the onset of floret abscission and leaf yellowing by 5 and 18 days, respectively. Additionally, when MWCNTs/PVP solution was applied to cut stems, water uptake remained consistently greater than that of the control. Additionally, MWCNTs/PVP increased the total chlorophyll content, soluble protein content, and POX enzyme activity of leaves while decreasing the malondialdehyde (MDA) content. The results indicate that this composite exhibited antimicrobial activity against gram-positive and -negative bacteria, particularly at a concentration of 3 mg L−1. This study demonstrated that adding MWCNTs/PVP to a vase solution of Alstroemeria cut flowers increased their longevity with minimal leaf yellowing symptoms compared to untreated cut stems. As a result, this nanocomposite can be used safely and effectively in vase solutions and in combination with other preservatives.
