“…Studying different preservatives in postharvest of lisianthus (Eustoma grandiflorum), Cavasini et al (2015) observed a decrease in total protein levels during the evaluation period. Similar results were reported by Vieira et al (2016) working with bird paradise stems (Strelitzia reginae). Eason et al (2002) also found that there was a decrease in protein content during the senescence of Sandersonia aurantiaca.…”

“…Postharvest senescence may be due to several factors, such as reactive oxygen species (ROS), presenting as discoloration and petal curvature (Trippi and Paulin, 1984). Many studies involving antioxidant properties were carried out with the aim of increasing longevity of the flowers (Reviewed by Amorim et al, 2017;Panavas and Rubinstein, 1998;Vaslier and Van Doorn, 2003;Gerailoo and Ghasemnezhad, 2011;Fan et al, 2015;Vieira et al, 2016;Fonseca et al, 2017).…”

Chrysanthemum is one of the most commercialized cut flowers on world market. After cutting, it becomes highly perishable due to the increased metabolic activity that leads to senescence. Thus, the experiment was carried out in order to evaluate action of maintenance solutions on the postharvest physiology cutting chrysanthemums of the cultivar Framint. A completely randomized design was used in the factorial scheme composed of two factors: four postharvest treatments and seven evaluation times. The flowers remained in the following maintenance solutions: citric acid solution, solution with boric acid, and salicylic acid solution at concentrations 100 mg. L-1 for both treatments in combination with 1% ethanol. During postharvest period, following analyzes were performed: fresh mass loss, volume of water absorbed, luminosity (petals), activity of the enzymes ascorbate peroxidase (APX), catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), total protein and total carbohydrate content. The treatment with citric acid + ethanol was the most adequate to conserve the quality and to prolong longevity of the flowers, being confirmed by the smaller loss of fresh mass, respiratory activity, better maintenance of carbohydrate and protein content.

It had as objective to evaluate the effect of 8-hydroxyquinoline and chlorine, isolated and mixed in and conservation of the stem stick of the emperor. Twenty of the stem torch ginger (Etlingera elatior), variety Red Torch were harvested, transported, and immersed in standardized solutions containing biocides for 48 hours. The biocide used were 100 mg L -1 of chlorine; 250 mg L -1 of 8-(HQC); 500 mg L -1 of 8-(HQC) and 50 mg L -1 of chlorine + 50 mg L -1 of 8-(HQC), the control corresponded to water. The stems stay immersed in water for nine days at 20 ± 4 ºC. Every 24 hours, the water in the container was replaced. During nine days, some measurements were realized of pH of the water in which the stems stay immersed, in the same way, it was measured the consumption/loss volume of the water for each 24 hours in the containers. The stems were weighed and also samples were taken from the base of the stems and pear ligule determination of peroxidase activity. In general, the use of solutions of 8-(HQC), 250 and 500 mg L -1 , make easier the flux of water in the vases, measured by the consumption of water; provided lower peroxidase activity at the base, independent of the pH of the solution and maintained lower peroxidase activities in the ligule. Thus, with the results obtained, it demonstrated promise the use of 8-(HQC), in the highest concentrations tested (250 and 500 mg L -1 ) for quality maintenance of cut stems of Etlingera elatior, variety Red Torch.
