“…Initially, citric acid maintained a higher diameter of floret, which could be due to the fact that this chemical reduced bacterial growth and prevented vascular blockages, but, later on, could not supply respiratory substrates for the opening florets. Similar results had been recorded by Kumari et al (2018) in cut tuberose cv. Calcutta Single.…”

“…Overall sucrose (3% and 4%) solution performed better to maintain the diameter of florets, as this solution provided adequate food sources or carbohydrates, resulting in higher floral diameter. Similar improvement was reported by Kumari et al (2018) in the opening of florets with high sucrose concentration in cut tuberose cv. Calcutta Single.…”

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.

“…Maximum length (7.41 cm) of floret was observed in treatment T 9 (sucrose 2% + AgNO 3 50 ppm + citric acid 100 ppm) (Table 3). Similar finding is given by Kumari et al, (2018) in cut tuberose that, maximum floret length (3.84) was observed in treatment with Sucrose 5% + AgNO 3 at 25ppm whereas minimum floret length (3.20) was observed in Control. Findings were in similar with Talukdar and Barooah (2010) on effect of pulsing and different holding solutions on flower quality and vase life of tuberose (Polianthes tuberose L.) cv.…”

Background: Arka Amar is a most popular variety of gladiolus which is used as cut flower and cut flowers are highly perishable materials and pregnable to large post-harvest losses. There is an immense post-harvest losses in value of cut flowers which is seen all along the marketing channels and it can be up to 40-50%. So, an experiment was carried out to find out the best combination of preservative solutions to enhance the vase life of Gladiolus (Gladiolus grandiflorus L.) var. Arka Amar. Methods: In this laboratory study during March 2022 to April 2022, different preservative solutions were analyzed to find out the maximum longevity of spikes. The experiment was laid out in C.R.D. with nine different combinations of sucrose, Al2 (SO4)3, AgNO3 and citric acid including control (distilled water). Result: The study revealed that the treatment T9 (Sucrose 2% + AgNO3 50ppm + citric acid 100 ppm) increased the percentage of water uptake both in weight and volume basis, minimize the days taken for opening of 1st floret (4.83 days), increase the length (7.41 cm) and diameter (13 cm) of floret, increase the percentage of opening of florets/spike (96.92%), maximize the longevity of floret (22 days) and flowering duration of spike (14.66 days). Visual scoring on appearance (8.71) and freshness (8.93) were also found significant for the above treatment combination.

“…Sucrose along with other various functions also helps in stomatal closure thus preventing water loss ultimately increases fresh weight (Abdulrahman et al, 2012). Germicidal and ethylene inhibition properties of AgNO3 increased the fresh weight of cut tuberose and rose 'Red One' when their cut stem was treated with silver nitrate solution and sucrose solution (Mirjalili, 2015;Kumari et al, 2018). Senescence in cut flower is mainly attributed to petals wilting that occur due to an imbalance between uptake of water and transpiration loss along with decreasing supply of food (carbohydrates).…”

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
