Cut snapdragons (Antirrhinum majus L. cvs. Fujinoyuki, Oakland, and Bismarck) were harvested at three different stages and pulsed with silver thiosulfate (STS). Then, the flowers were treated with several preservative solutions to test the effects on vase life and flower quality. Proper storage methods were also investigated. The best harvesting time of snapdragon was when seven to nine florets were opened in a spike. The flowers harvested at this stage had more fresh weight, increased number of opened flowers per spike, and longer vase life than those harvested at earlier stages. Pulsing with 0.2 mM STS for 16 h improved flower quality and prolonged vase life. The preservative solution containing 2% sucrose + 150 ppm 8-hydroxyquinone citrate (HQC) + 25 ppm AgNO3 prolonged vase life. However, this solution caused longer internode between florets and excessive elongation of spike. The preservative solution containing 2% sucrose + 150 ppm HQC + 25 ppm AgNO3 + 50 ppm daminozide improved flower quality by prolonging vase life, reducing the length of internode between florets, and preventing excessive elongation of spike. The flowers held in 50% 7-Up had 2 times prolonged vase life compared to water control. The flowers held in 4% ethyl alcohol also had prolonged vase life and increased fresh weight. Ethylene caused floret abscission and STS pretreatment prevented this floret abscission. Ethylene production in cut snapdragons maintained 2 to 6 nl/g fresh weight per h during vase life. The prolonging storage at low temperature (1C) shortened vase life. The flowers pretreated with STS, and then held in preservative solution during cold storage, had better flower quality and longer vase life than those in plain water.

Introduction: The procedure to synthesize silver nanoparticles (SNPs) from Prunus cerasoides leaf extract and their effect on vase life and flower quality of cut carnation were investigated. Methods: SNPs were bio-synthesized from Prunus cerasoides leaf extract and characterized by using UV-Vis technique, TEM, and SEM images. The postharvest responses of carnation cut flowers to the biosynthesis SNPs were evaluated through vase life, relative fresh weight, vase solution uptake, flower diameter of cut carnation. Results: SNPs were synthesized under optimum conditions, including using the extract of leaf heating at 60 oC in 30 min, 4 mM of silver nitrate, pH of 11, and 180 min of reaction time. SNPs exhibited antimicrobial activity and then alleviated the bacterial development in the preservative solution. All treatments with SNPs had improved the vase life and quality of cut carnation compared to the control. A vase solution containing 2% sucrose enhanced the carnation cut flowers. Conclusions: The preservative solution containing 25 ppm SNPs and 2% sucrose showed the best effect. SNPs could be used as a promising antibacterial agent applied in the preservative solution for cut carnation flowers.

Several pulse solutions were tested for their effectiveness in preventing leaf senescence on four cut oriental lily cultivars (Lilium sp. `Acapulco', `Kissproof', `Noblesse' and `Star Gazer'). Stems were pulsed 24 hours after harvest for 1 hour, stored in boxes in the dark for 5 days at 3 °C (37.4 °F) then evaluated in postharvest conditions. A new commercial product called Chrysal BVB, a proprietary mixture manufactured by Pokon & Chrysal (Miami) containing cytokinine and gibberellic acids, was the most effective product tested. Chrysal BVB [1 mL·L–1 (0.1%)] prevented leaf chlorosis and abscission on `Acapulco' and `Noblesse' and significantly reduced it by 82% on `Star Gazer' and by 69% on `Kissproof'. Stems pulsed in Fascination, a commercial mixture containing 1.8% gibberellins (GA4+7) and 1.8% benzyladenine [5.4 mg·L–1 (ppm) each], virtually prevented leaf chlorosis on `Noblesse', reduced it by 50% or more on `Acapulco' and `Star Gazer', and significantly delayed it 8 days on `Kissproof'. A 10 μm (2 ppm) pulse in thidiazuron, a substituted phenylurea with cytokinin-like properties, delayed leaf chlorosis on `Star Gazer' but to a lesser extent compared to BVB and Fascination. Chrysal SVB, a propri-etary mixture manufactured by Pokon & Chrysal containing gibberellic acid, had no effect on reducing leaf chlorosis on `Star Gazer'. None of the pulse solutions had adverse effects on bud opening, flower quality or vase life. Maintaining stems in a bulb flower preservative significantly reduced leaf chlorosis and abscission in all cultivars when stems were not pretreated with a pulse solution or when a pulse solution was ineffective.

The short vase life is the major problem in the cut flower industry. This study was conducted to evaluate the role of different vase solutions and oils in enhancing the quality and vase life of lily cut flowers. Salicylic acid (SA; 300 mg L−1), citric acid (CA; 300 mg L−1), gibberellic acid (GA; 100 mg L−1), and clove oil (200 mg L−1) were used as vase solutions. These treatments were applied after pulsing with preoptimized sucrose 5%. It was found that SA (300 mg L−1) + sucrose (5%) improved the performance of cut flowers, which further increased the longevity of all tested lily cultivars up to eight days and the longest vase life by 17.6 days. The maximum change in fresh weight (5.60 g), increase in chlorophyll contents (3.2 SPAD value), highest protein content (6.1 mg g−1 FW), and increase in the activities of superoxide dismutase (SOD) (51.0 U g−1 protein), catalase (CAT) (36.3 U g−1 protein), and peroxidase (POD) (41.6 U g−1 protein), were recorded with the CA (300 mg L−1) + sucrose 5%. Among the cultivars, “Zambesi” performed best compared to “Sorbonne” and “Caesars”. The maximum anthocyanin contents (198%) were recorded in “Caesars”. In conclusion, among the different preservative solutions, SA performed best to prolong the vase life and quality of lily cut flowers.

The present investigation was carried out with the aim to find out the effect of integrated nutrient management on flower quality of French marigold (Tagetes patula L.) cv. Pusa Arpita at the Horticultural Research Centre, Department of Horticulture, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, U. P., India, during the year 2019-2020. The study consisted of organic manures (FYM and Vermicompost), Bio-fertilizers (PSB and Azotobacter), and the recommended dose of inorganic fertilizer (RDF) (150:60:60 kg NPK/ha). The combined application of ½ RDF + ½ PSB+ ½ Vermicompost showed significant influence on quality parameters that include; maximum flowering duration (60.66 days), circumference of flower (22.51 cm), number of florets per flower (136.55), length of flower stalk (6.44 cm), and the vase life of flowers were enhanced by up to 7.47 days over the control that was recorded in the same treatment. The study concluded that there was a significant influence of the combined application of organic manure, bio-fertilizer and inorganic fertilizer on French marigold to enhance the flowering quality and their characters.

Gladiolus is an important cut flower in the world, and its preference in Pakistan is next to roses. But the main problem that occurs in gladiolus is that it has short vase life. The present experiment was conducted with an objective to investigate the effect of four preservative solutions [distilled water, Sucrose (3%), AgNO3 (250 ppm), AgNO3 (250 ppm) + Sucrose (3%)] and packaging material on postharvest quality of three gladiolus varieties, “Tissue, White Prosperity and Alexandra”. Packaging material consists of control treatment (without packaging), packaging of cut spikes with 100 ppm acetic acid soaked cotton and packaging of polyethylene sheet after sucrose pulsing. The experiment was arranged as two factorial laid out according to completely randomized design (CRD) having three replications. Results showed that preservative solution having combination of AgNO3 (250 ppm) + Sucrose (3%) significantly improves days to open basal floret, floret opening percentage (%), bloom spread (inch), floret length (inch), floret diameter (inch), fresh spike weight (g), dry spike weight (g), fresh weight loss (%) and vase life (days). Moreover, this treatment was also effective in reducing the wilting (%) in all gladiolus varieties. However, for solution uptake (mL/spike) and solution balance (ml/spike), AgNO3 (250 ppm)alone gives the best results. For packaging treatment, the pulsing of a cut spike with 20% sucrose followed by polyethylene sheet wrapping proves to be effective. Among the varieties, Alexandra performed better for all quality parameters in comparison to White Prosperity and Tissue
