Alstroemeria is one of the most popular cut flowers in European Union owing to its postharvest longevity and broad color spectra. Nevertheless, premature wilting decreases the esthetic value of flowering branches even before the opening of the secondary florets in the fluorescence. The present study evaluated different biochemical and morphological traits of Alstroemeria cut flowers in order to screen the longevity of eight cultivars of Alstroemeria cut flowers including (Topaz, Chicago, Mayfair, Onyx, Frosty, Bellevue, Samantha, and Dimension). Traits such as longevity, wilting, water uptake, chlorophyll content, total soluble solids, relative water content, catalase activity, peroxidase activity, and protein content were evaluated. Data were subjected to the statistical and cluster analysis. The results showed that Mayfair and Frosty cultivars have the greatest distance from another. Mayfair had the lowest longevity. Frosty exhibited the most significant difference and was the most different cultivar from other cultivars in terms of biochemical traits, so that it was clustered in a separate group. As a result, two cultivars with the longest and the shortest longevity was determined. Maximum peroxidase activity was related to Frosty, differing significantly from that of Mayfair.

Alstroemeria (Alstroemeria hybrida) is one of the most important cut flowers in the world. The aim of this study is investigating on the effect of dill and cumin essential oils on physiological and microbiological traits of alstroemeria cut flowers. Hydro-distillation method and GC isolated the essential oils of seed and GC/MS examined the chemical compositions of the samples. This experiment carried out as factorial based on completely randomized design with two factors of essential oils of dill and cumin (50 and 100 ppm). The second factor was used of methods (pre-harvest, post-harvest). The results showed that the dill essential oil treatment (100 ppm) in pre-harvest was the best treatment for all known traits. 11 colonies of bacteria were identified in stem end of cut alstroemeria flowers; which are E-coli, Enterobacter, Klebsiella, Proteus, Serratia, Citrobacter, Pseudomonas, Staphylococcus aureus, Streptococcus, Bacillus cereus and Actinomycetes. Due to the positive impact of dill essential oil (100 ppm) in the pre-harvest method in improving traits associated with vase life of cut alstroemeria flowers, these treatments are recommended.

In order to improve the quality of cut rose ‘Dolce Vita’, an investigation was performed with 20 treatments, 3 replications, and 2 plants in each replicate in a greenhouse with the open soilless culture system. The treatments included control (distilled water), putrescine (Put) at the rates of 1, 2 or 3 mM, spermidine (Spd) at the rates of 0.5, 1 or 1.5 mM, spermine (Spm) at the rates of 1, 2 or 4 mM, calcium sulfate (CS) at the rates of 2.5 or 5 mM, and the combined treatments of Put + CS and Spd + CS. The traits such as stem height, flower length and diameter, stem fresh weight, vase life, and leaf mineral uptake including N, P, K, Ca, Fe and Zn were measured. According to the results, the combined application of polyamines (PAs) with CS had a significant influence on increasing the parameters such as stem height, flower length and diameter, stem fresh weight, and vase life. The rose flowers treated with Put 2 mM + CS 2.5 mM, Spd 0.5 or 1 mM + CS 5 mM showed the highest vase life (16.2, 16 and 16 days, respectively) compared to other treatments. The combined application of PAs and CS enhanced the uptake of minerals when compared to their individual application. The plants sprayed with Spd and CS exhibited the highest Ca uptake. Generally, the results showed that PAs and CS increased quantitative and qualitative characteristics of rose flower ‘Dolce Vita’ in soilless culture system due to the increased uptake of minerals. It can be inferred that the foliar application of PAs and CS sulfate can be effective in improving the quantitative and qualitative traits of this cultivar.

This research performed as a factorial experiment based on a completely randomized design with three replications under 23 ± 2 °C, 60 ± 5% RH and 12 µmol m−2 s−1 light intensity (cool white florescent tubes) under a daily light period of 12 h. Results showed that 125 mg L−1 silver nanoparticles without sucrose or with 2% sucrose had the lowest stem end bacteria. Pulse treatments with silver nanoparticles at all concentrations improved solution uptake, maintenance of the relative fresh weight, flower diameter and chlorophyll fluorescence ratio (Fv/Fm) as compared to control. The highest amount of flower opening with the largest flower diameter was observed in 75 mg L−1 pulsed silver nanoparticles with 2% sucrose solution on day 9 of vase period. Control flowers (deionized water) without or with 2% sucrose exhibited the shortest vase life. The concentrations of 75 and 125 mg L−1 with 2% sucrose or without it had the longest vase life as compared to other treatments.

In this study, characteristics such as vase life, dry matter, increasing ° Brix, the percentage of flower opening, chlorophyll a and b and ionic leakage were evaluated. The results showed that coconut juice at a concentration of 5% has the maximum vase life (17.39 days), although it has no significant difference with different levels of benzyladenine and 10 and 20% coconut juice treatments. 10% coconut juice with 2.58 and 0.88 has the highest ° Brix and flower opening index, respectively. Treatments of 50 mg l-1 benzyladenine, 5 and 10% coconut juice had the maximum impact on the amount of dry matter. The most successful treatments for reducing ionic leakage are two treatments of 5% coconut juice and 100 mg l-1 benzyladenine. All treatments cause maintenance of chlorophyll a and b compared to the control, and two treatments of 50 mg l-1 cycloheximide and 5% coconut juice had the highest content of chlorophyll a and b, respectively among treatments. According to the obtained results, using 5% coconut juice in the vase solution can effectively improve the vase life of alstroemeria cut flowers.

In order to improve the postharvest quality and the export ability of cut rose (Rosa hybrida L.) cvs. Happy Hour and Bordeaux, the effect of 1-methylcyclopropene (1-MCP) as an ethylene inhibitor, was investigated. 1-MCP was used at 0.3, 0.4, 0.5 and 0.6 g m-3 for 18 h at 8 °C to simulate the transport of flowers. 1-MCP treatment significantly prolonged the vase life and minimized the weight loss of both cultivars compared to the control, however the response of Happy Hour cultivar was higher than the Bordeaux cultivar. 1-MCP treatment enhanced the relative water content (RWC) of flowers. The treatment of 1-MCP significantly retarded the degradation of chlorophyll and carbohydrate contents during vase life evaluation in both cultivars. The ethylene production was significantly decreased by applying 1-MCP treatment. The membrane stability index (MSI) was maintained while malondialdehyde (MDA) was decreased in response to 1-MCP treatment. The best treatments in this concern were 1-MCP at 0.4 and 0.5 g m-3 for Happy Hour and Bordeaux cultivars, respectively. 1-MCP treatment was recommended to inhibit the negative effects of ethylene on rose cultivars tested.

Stem and peduncle bending by the weight of the flower is one of the main postharvest problems in gerbera (Gerbera jamesonii Bolus.) and sometimes caused stem crushing or water loss. In this research, silicon and salicylic acid were applied to enhance the mechanical strength of inflorescence stem, and the results revealed that stem curving was decreased by silicon and salicylic acid treatments. Shear strength and lignin content were increased by SA treatments at both upper and lower parts of the stem. It seems that lignin content was associated with shear strength at upper part of stem. Additionally, silicon content of flower stem was significantly increased under silicon application and mechanical strength of the lower part of stem has correlation with silicon content in stem tissue. These results suggested that silicon and salicylic acid application could enhance the mechanical strength of inflorescence stem and improve the cut flower quality in gerbera.

This experiment was conducted to determine the effect of foliar spray with polyamines on postharvest life of chrysanthemum cut flowers in the horticulture laboratory of Islamic Azad University of Rafsanjan in 2015. For this purpose, an experiment was conducted based on a completely randomized design with three replications with spermidine, spermine and putrescine treatments at 1, 2 and 3 mM concentrations. Different parameters such as vase life, quality, weight loss, dry matter percentage, chlorophyll, total soluble dissolved, protein, water uptake, ACC oxidase and SOD were measured. The results showed that all treatments significantly increased the survival and quality of flowers as compared to control. Spermidine (3 mM) resulted in maximum vase life so that after 9 days, the flowers of this treatment were of a good quality. The lowest weight loss and highest level of dissolved solids were observed in 3 mM spermidine and then, in 2 mM spermidine. ACC oxidase enzyme activity was reduced by a factor of quarter in 3 mM spermidine treatment as compared to control. On the other hand, superoxide dismutase activity in this treatment was 3 times higher than that in control. The highest amount of chlorophyll was observed in the treatment of 3 mM spermidine and putrescine. Solution uptake was increased when polyamines were applied so that the highest solution uptake was observed in the first stage of measurement in relation to 3 mM putrescine. But in the second stage of measurement, 1 mM spermine outperformed. Treatments had no significant effect on dry matter percentage and protein amount in leaves of cut flowers. So, according to the results of this test, treatment with 3 mM spermidine is recommended as the best treatment to enhance the quality and vase life of chrysanthemum (Chrysanthemum morifolium cv. 'Bright Golden Ann') cut flowers.

Tuberose (Polianthes tuberosa) is one of the most important cut flowers with fragrant buds. To prolong vase life of tuberose, proper preservative solution applying is necessary. For this purpose, two types of chemical and natural treatments were used. Applied treatments were benzyladenine (50, 100, and 150 mg l-1), the extracts of rosemary and Eucalyptus (12, 25 and 50%) and sour orange fruit extract (3, 4, 5 and 6 ml l-1). Sucrose 4% was used in all solutions. Measured characteristics included the vase life, the percentage of opening of the buds, the relative fresh weight, the solution absorption, the total soluble solids, chlorophyll a, b and total chlorophyll. The results showed that the maximum vase life was obtained in benzyladenine treatment of 50 mg l-1 (11.66 days) and the minimum vase life was obtained in the control treatment and rosemary extract of 50% (6.33 days). The highest percentage of buds opening was related to the benzyladenine treatment of 150 mg l-1. The maximum relative fresh weight and solution absorption were obtained in the benzyladenine treatments of 100 and 50 mg l-1, respectively and the maximum amount of total soluble solids was obtained in Eucalyptus extract treatment of 12 %. In addition, the maximum amount of chlorophyll a, b and total was related to the treatment of sour orange fruit extract of 4.5 mg l-1. In general, the results showed that benzyladenine had the maximum vase life but, natural compounds especially the extracts of Eucalyptus and sour orange had the significant effect on the vase life and the other traits of tuberose cut flowers and they can be used as simple, healthy and cheap compounds.

Gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in Iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. To increase vase life of gerbera cut flowers cv. ‘Alain Ducasse’, the essences of Eucalyptus and Rosa damascena, the combination of these two essences at a concentration of 200 mg L-1 with 4% sucrose and only 4% sucrose were used as treatment and distilled water was used as control treatment. In current study, the characters of vase life, wet weight, total soluble solids, solution uptake and bent neck were examined. Maximum and minimum of vase life were achieved in Eucalyptus essence treatment (12.33 days) and control (7 days), respectively. Although, Rosa damascena essence and its combination with Eucalyptus essence also increased the vase life. The maximum fresh weight and solution uptake was obtained treated with Eucalyptus oil. The maximum fresh weight and absorption of solution were obtained in treatment with Eucalyptus essence. The maximum amount of soluble solids was obtained in the treatment of sucrose. In addition, control treatment has the maximum bent neck. The overall results showed that the use of Eucalyptus and Rosa damascena essence in combination with sucrose can be used as a preservative solution of gerbera cut flowers.

The anti-senescence biogenic polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) are involved in plant growth processes and responses to stress. The physiological mechanism of exogenous Put to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM Put and then held at 25 ◦C up to 12 days. Exogenous Put supply at 2 mM extended vase life, which was associated with reduced electrolyte leakage and MDA content. Put treatment also reduced activity of lipoxygenase (LOX), is responsible for membrane lipid peroxidation. Put treatment also enhanced activities of catalase (CAT) and ascorbate peroxidase (APX) and decreased H2O2 accumulation during vase life. Thus, exogenous Put supplycould maintain membrane integrity by increasing antioxidant system activity, thereby retarding the senescence of cut lisianthus flower during vase life.

The aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment involving the pulsing treatment with gibberllic acid (GA3) at 0, 20, 40 and 60 mg L-1, for 24 hours, and holding them in sucrose at 0, 2 and 3% with 250 mg L-1 of 8- HQS as an antimicrobial agent for all holding treatments was conducted. The study was performed as a factorial experiment based on a randomized completely design (RCD) with three replication for each combination treatment. Applying GA3 pulse treatment alone at all concentrations increased significantly vase life and its effect enhanced with sucrose holding at 2 and 3% compared with control. The effect of GA3 pulsing in increasing of stem relative fresh weight (RFW) and solution uptake (SU) was hastened by sucrose holding treatment at 2 and 3%. Highest amount of flower opening and petal water content during vase life period was observed in 60 mg L-1 of GA3 pulsing and sucrose 3% holding treatment which had been longer flower diameters and greater petals. Gibberellic acid pulsing alone and along with sucrose holding treatment at all concentrations caused to prevention of leaf chlorophyll degradation compared with control. In conclusion, GA3 pulsing at 40 mg L-1 along with sucrose 2% holding treatment had a significant effect on improving vase life and other qualitative attributes of cut rose flower cv. Velvet.

In this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of Alstroemeria ҅Modena҆ cut flowers. The experiment was done in a factorial experiment based on RCD with 16 treatments, 3 replications and 48 plots. The flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μM) and salicylic acid (0, 100, 200, and 300 mg l-1) for 24 hours. Then cut flowers were put in a preservative solution containing 3% sucrose and 300 mg l-1 8-HQS.Then, vase life and quality traits such as fresh weight, dry weight, water uptake, amount of soluble solids (˚brix) and cell membrane stability (electrolyte leakage) were evaluated during examination. The results showed that the concentration of 200 mg l-1 salicylic acid, has the highest water uptake and lowest reduction of fresh weight in comparison with the other treatments. In all treatments except for the control, dry weight and soluble solids increased.Also, 20 μM thidiazuron and 100 mg l-1 salicylic acid showed the greatest stability of the cell membrane compared to the control treatment.

The present study has assessed the effect of Cola in increasing flower longevity of flower and delaying aging of cut Alstroemeria ‘Balance’. Distilled water was used as control. Traits of flower diameter, solution absorption ,anthocyanins, total soluble solids and chlorophyll were measured at 3 times and vase life was measured daily. Based on the results, flower diameter, anthocyanins and chlorophyll were significant at 1% level and solution absorption was significant at 5% level. The highest flower longevity was related to concentration 500 ml L-1 Cola with 16 days, while the control was 9 days. The highest solution absorption rate belonged to 250 ml L-1 treatment of Cola. Cola concentration of 375 ml L-1 had the greatest flower diameter and chlorophyll. According to the results of means comparison, amount of anthocyanin in different concentrations of Cola was the same. In general, Cola delayed aging Alstroemeria flowers due to having compounds such as citric acid, phosphoric acid, sugar,sodium benzoate, etc., and by providing flowers with required carbohydrates and antimicrobial effect.

The abscission of Alstroemeria petals is the serious problem at the industry of cut flowers of this plant. In this study, cut Alstroemeria cv. Bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg L-1), -5-sulfosalicylic acid (1 and 1.5 mM) and sucrose (5 and 10%) for 24 hours. The distilled water was used as control. After treatment, the flowers were placed in distilled water, and maintained at temperature of 22±2oC, 70±5% relative humidity, and 15 mmol m-2 s-1 light intensity 12 hours per day. The results showed that 50 and 100 mg L-1 gibberellic acid could significantly delay flower senescence with 3.33 and 3 days, respectively as compared to the other treatments. The highest petal anthocyanin content was found at gibberellic acid (50 and 100 mg L-1), benzyladenine (100 mg L-1) and 5-sulfosalicylic acid (1.5 mM) than other treatments. Conversely, lipid peroxidation content and catalase enzyme activity was lower in these treatments as compared to the control. The protein content of gibberellic acid (50 and 100 mg L-1) pulse treated flowers was higher than other treatments. In contrast, the flowers treated with 100 mg L-1 gibberellic acid showed the lowest peroxidase enzyme activity. Overall, the vase life of Alstroemeria cut flowers cv. Bridal increased in both gibberellic acid treatments (50 and 100 mg L-1) than other studied solutions.

Maintaining quality and longevity of cut flowers is one of the critical issues in the floriculture industry, especially in cut flowers; and one of the most important problems in chrysanthemum, as one of the most popular cut flowers. Therefore, an experiment was conducted based on completely randomized design as pulse treatment with the three factors: tea extracts with 4 levels (5, 10, 20, and 40 %), 8-hydroxy quinoline sulfate with 4 levels (100, 200, and 400 mg l-1), and rifampicin with 3 levels (100, 200, and 400 mg l-1) on spray chrysanthemum (cv. Purple) with three replications. According to the results, the 20% tea extract treatment and 100 mg l-1 8-hydroxy quinoline sulfate treatment showed the highest vase life, petal protein, total chlorophyll, water absorption, and petal carotenoid.

Chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. In order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a RCD with 10 treatments: Artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), Rifampin at 3 levels (100, 200 and 300 mg l-1) and the control plants in 3 replications. Analysis of variance showed that effect of treatments on measured traits was significant at p£0.05 or p£0.01. Mean comparisons also revealed that 30% of Artemisia oil, 200 mg l-1 amoxicillin and 200 mg l-1 rifampin caused the longest vase life, the highest preservative solution uptake. petal's soluble protein contents, leaf chlorophyll and maximum fresh weight.

Ten gerbera cultivars (‘Labinel’, ‘Lilla’, ‘Alp’, ‘Alberino’, ‘Bonnie’, ‘Avemaria’, ‘Mammut’, ‘Lexus’, ‘‘Terramixa ’ & ‘Sarolta’) were evaluated for their growth, yield and quality characteristics under protected conditions during 2011. Among the cultivars studied, there were highly significant variations observed for growth, yield and quality parameters. Longest stalk length (60.3 cm) was exhibited by the cultivar ‘Alberino’ followed by ‘Lexus’ (59.0) and ‘Mammut’ (54.0 cm). The same cultivar also produced flowers with maximum diameter. With respect to vegetative parameters like number of leaves per plant and plant spread were also more in the same cultivar. Maximum number of flowers 135 per square meters was recorded in cv. ‘Avemaria’ (135) followed by ‘Alberino’ (125). Maximum vase life was recorded in cultivars ‘Alberino’ and ‘Lexus’ (6.6) followed by ‘Mammut’ (5.6) and ‘‘Sarolta’’ (5.6). Excellent quality flowers were observed in cultivar ‘Alberino’ (4.8) followed by ‘Lexus’ (4.4). Cultivar ‘Alberino’ and ‘Lexus’ were found superior with respect to growth, yield and vase-life characteristics under protected conditions.

The postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. Cut roses were obtained from commercial area of Siliguri. To assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (CA) (300 mg/ml) and 8-hydroxyquinoline (8-HQ) (200 mg/ml) with various concentrations (1% to 8%) of sucrose solution. Each treatment consisted of 3 replicates. Cut roses were treated with different solutions and were kept at normal room temperature (20o C) under normal day light and natural ventilation. The biochemical parameters such as phenol, flavonol content, total soluble sugar, reducing sugar, non-reducing sugar, and for antioxidant property 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity was determined in flowers treated for 0, 2, 4, 6 and 8 days, respectively. The physiological parameters such as vase life, water uptake, transpiration rate and water balance were also observed. The results demonstrated that the flowers which were treated with 5% of sucrose extended the vase life of cut flower from 4 to 8 days by improving the carbohydrate supply and reducing oxidative stress mediated damages during rose flower senescence.
