ABSTRACT This experiment was conducted to study the effectiveness of different preservative solutions on vase life and quality of angelica cut inflorescences cv. Single. The concentrations of citric acid at 100, 200 and 300 mg L-1, sucrose at 3% and 4% and H2O2 at 0.1%, 0.2% and 0.3% were used as preservatives, while distilled water was used as control. The single factor experiment was laid out in a completely randomized design (CRD) with three replications. Citric acid and H2O2 solutions effectively inhibited bacterial growth-related blockage in the vascular tissues, but had adverse effects on the vase life. The inflorescences stored in sucrose (3% and 4%) solutions remained fresh up to 10 days after preservation (DAP), maintaining good solution uptake, controlling transpiration loss and gaining higher relative fresh weight. Different quality parameters like floret diameter and number of opened florets were also significantly higher in inflorescences preserved in sucrose (3% and 4%) solution, followed by control, citric acid and H2O2, respectively, in different DAP. Overall, the inflorescence of cut tuberose preserved in sucrose, particularly at 4% solutions, showed better postharvest quality than other preservatives and maximum vase life.

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

Abstract Quality of cut flowers is an important issue at postharvest as well as an important factor contributing to marketing of and profitability from the tuberose. In this study, the effects of citric acid (CA) and hydrogen peroxide (H2O2) added to the vase water on postharvest quality of tuberose cut flowers were investigated. CA was applied in concentrations of 50, 100, 200, 400 mg·dm−3 and H2O2 in concentrations of 10, 20, 40 and 80 mg·dm−3 and distilled water as control treatment. Results showed that both compounds had significant positive effects on solution uptake, wilting and abscission of florets, relative water content, chlorophyll content, and vase life duration. The effects of 100 and 200 mg·dm−3 of CA and 20 and 40 mg·dm−3 of H2O2 proved to be more effective than other treatments. Both compounds increased the vase life of tuberose cut flowers and CA at concentrations 100 and 200 mg dm−3 and H2O2 at concentrations 20 and 40 mg dm−3 doubled this time up to 14-17 days.

ABSTRACT This study was carried out to assess the postharvest quality preservation of feijoa(Acca sellowiana Berg) flowers in response to treatments with different preservative solutions and 1-methylcyclopropene (1-MCP). Recently opened feijoa flowers were harvested in the morning (between 8h and 10h) and immediately after pulsed with preservative solutions of salicylic acid, ascorbic acid and sucrose, all at doses of 0 (control), 2, 5 or 10%, and treated with 1-MCP at doses of 0 (control), 250, 500 or 1,000 nL L-1. Each trial with preservative solutions or 1-MCP treatment was a distinct experiment conducted in a completely randomized design with four replicates, each replicate with four flowers. After the treatment, the flowers were stored for 12 days at 10±1 oC and 85±5% RH. At every two-days intervals the flower petals were visually evaluated for wilting and darkening according to a hedonic scale varying from 1 (less intense) to 5 (more intense). Petal color was ranked from 1 (intense pink) to 5 (white). The 1-MCP at 500 nL L-1 and the salicylic acid (regardless of the dose) delayed the changes of petal color for up to eight and six days of storage, respectively. Flowers treated with salicylic acid, 1-MCP or ascorbic acid had a more substantial delay in petal wilting. Flowers treated with salicylic acid had wilting rank of 2 after six days of storage when treated with doses of 5% or 10%, and after eight days when treated with the dose of 2%, while flowers treated with 1-MCP at 500 and 1,000 nL L-1 and ascorbic acid at 2% and 5% had wilting rank of 2 after four days of storage. The most substantial delay of petal darkening (until the fourth day of storage) was achieved with 1-MCP at 500 nL L-1.

ABSTRACT: This study aimed to verify the best storage temperature in the postharvest quality conservation of inflorescences of gerberas cv. 'Intenza'. Inflorescences were kept in distilled water and stored at the temperatures of 22ºC (control); 12ºC; 8ºC and 4ºC. The experiment was conducted in a completely randomized design in split plot with two factors: 4 treatments (temperatures) X 4 evaluation dates (0, 3, 6 and 9 days). It was used three replicates, with three inflorescences each. It were evaluated the variation of fresh mass, relative water content, soluble and reducing sugars content and longevity. Results were submitted to analysis of variance and means compared by Tukey test at 5% of probability. The inflorescences of gerbera maintained at 4ºC, 8ºC and 12ºC showed a greater postharvest life compared with the inflorescences of the control, highlighting those kept at 4ºC which presented less loss of mass and higher soluble sugar content; thus, maintaining the quality of gerberas for a longer period, with vase life of approximately 15 days.

This study aimed to verify the effect of the association between refrigeration and packaging on the preservation of postharvest quality of pitombas during storage. The fruits were harvested, transported to the laboratory, where they were selected, washed with neutral detergent and drinking water, and left to dry. Subsequently, the fruits packed in polypropylene (PP), low-density polyethylene (LDPE), polyethylene terephthalate (PET), polyvinyl chloride (PVC) + expanded polystyrene (EPS), and no packaging (Control). After this process, they were stored at temperatures of 6, 8, 10, 12, and 14±1 °C at 75±5% relative humidity (RH). The fruits were evaluated during 12 days for postharvest preservation, firmness, soluble solids content, pH, hue angle and chroma of the peel, with three replications of 10 fruits each, using a completely randomized design in a 5 × 5 × 7 factorial scheme (5 temperatures × 5 packages × 7 days of analysis). The results were subjected to analysis of variance (P≤0.05) and, when significant, the means were compared using the Scott-Knott test and regression at a 5% significance level. The use of LDPE packaging associated with refrigeration at 6 °C can be used to store pitombas for 12 days, as these conditions preserved the evaluated parameters, guaranteeing fruit quality.

An experiment with Hippeastrum flower (Hippeastrum hybridum Hort.) cv. ‘Apple Blossom’ comprising three sucrose concentrations viz. 0 (control), 2 and 4 % and five aluminium sulphate concentrations viz. 0 (control), 0.25, 0.50, 0.75 and 1.0 mM at the Horticulture Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh during the period from April 01 to April 30, 2009. The experiment was laid out in a Completely Randomized Design (CRD) with three replications. Sucrose, aluminium sulphate and their combinations had significant influence on most of the parameters studied. Transpiration loss and water uptake ratio decreased significantly with the increased sugar levels and aluminium sulphate upto 0.75 mM beyond which they were increased. Transpiration loss and water uptake ratio was found minimum in the vase solution containing 4% sucrose (0.78) and 0.75 mM aluminium sulphate (0.80), which ultimately resulted in an enhanced vase life (9.2 days for sucrose and 9.11 days for aluminium sulphate) of cut Hippeastrum flower. A linear relationship between water uptake and vase life of flowers was found (y = 0.056x + 5.791). Sucrose 4% and aluminium sulphate 0.75 mM in combination gave maximum total water uptake, maximum days to onset of deterioration, the highest average fresh weight of single scape at 6th and 10th day after setting the trial. Transpiration loss and solution uptake ratio was found maximum in the combination of 4% sucrose and 0.75 mM aluminium sulphate (0.48) with the longest vase life of 10.33 days of cut Hippeastrum flower cv. ‘Apple Blossom’.Bangladesh J.

This study aimed to evaluate the influence of homeopathic products in diets of quails in the egg quality when submitted to different storage periods. In the trial we used 200 Japanese quails in a completely randomized design with 4 diets: reference diet, vehicle used in homeopathic products and 2 homeopathic products - Fertsigo® and Ovosigo® with ten replicates of three eggs in each. Egg quality parameters were evaluated during 3 storage periods. Data were evaluated as repeated measures in time, the effects of the interactions between treatments and time as well as their isolated effects were verified. There was the interaction between homeopathic products and storage time in the parameters of albumen and yolk height, Haugh unit, and yolk index, in which a reduction was obtained over time. For egg weight, yolk, albumen and shell, percentage of albumen, and percentage of eggshell there was a significant effect only for homeopathy. The inclusion of homeopathic additives increased egg weight. It is indicated the addition of the product with homeopathic basis Ovosigo® and FertSigo® in diets of Japanese quails in the laying phase resulting in better egg and components but did not influence the quality maintenance of eggs of Japanese quails in the periods evaluated.

Mabolo (Diospyros blancoi A. DC) is an underutilized fruit in the Philippines. To add value and maximize the utilization of this nutritional fruit, the potential of mabolo for the production of highly saleable baked products, such as tarts, was explored. Specifically, the study aimed to formulate a custard tan filling with mabolo flesh as a flavorant using a single factor experiment arranged in a Completely Randomized Design (CRD). Six levels of mabolo flesh (0, 15, 30, 45, 60, & 75% w/w) were used. The sensory attributes for color, taste, aroma, texture, flavor, and general acceptability, were evaluated. The optimum formulation of the tart filling was determined using Regression analysis. Results showed that mabolo custard tart filling had yellowish-brown to brown color, moderately sweet to sweet taste, and soft to slightly fibrous texture. The mabolo fruit aroma and flavor in the tarts ranged from having none to perceptible. The Analysis of Variance revealed that different levels of mabolo flesh cause a significant effect on the color (p<0.01). The optimum formulation and the recommended level of mabolo flesh in custard tart filling production was 80.54% w/w.

Two experiments were conducted to evaluate the effect of different preservative solutions on maintaining postharvest quality of red roses cultivar ‘Carola’. The treatments evaluated in both experiments were five preservative solutions: (S) sucrose (1%) (SAC) sucrose (1%) + citric acid (0.2 g L-1), (SACH) sucrose (1 %) + citric acid (0.2 g L-1) + sodium hypochlorite (1%) (SACA) sucrose (1%) + citric acid (0.2 g L-1) + rosemary oil (Rosmarinus officinalis L.) (100 uL L-1), (SACG) sucrose (1%) + citric acid (0.2 g L-1) + Oil Ginger (Zingiber officinale) (100 uL L-1). In the first experiment the rods were maintained for 10 days in refrigerator at 3 ± 1 °C and in the second experiment were maintained for five days in refrigerator (3 ± 1 °C) and five days at ambient conditions (19 ± 1 °C) . The variables evaluated were swelling, curvature of the floral stalk, browning petals, floral opening and colored petals, in both experiments, and coloring of the petals in the second experiment. The evaluations were performed every two days during the storage period in experiment 1, and daily during the shelf period in experiment 2. The experimental design in both experiments was a randomized complete block design with four replications and two branches each. In the first experiment, the use of sucrose was shown to be as effective as the other preservative solutions, preserving the roses up to 10 days in cold storage at 3 ± 1° C. In the second experiment, for the solution containing sucrose alone, the use of sodium hypochlorite, rosemary oil, and ginger oil showed the best results in maintaining the quality of the rods, and essential oils gave better preservation of roses.
