“…A massa fresca em flores de corte indica que quanto mais próximo de 100% maior é a conservação de suas reservas (SANCHES et al, 2016). A perda de massa fresca deve-se ao processo de transpiração e também à redução da condutividade de água durante o processo de senescência da haste floral (DIAS-TAGLIACOZZO et al, 2005).…”

O copo de leite é muito apreciado tanto como flor para uso em arranjos florais bem como em jardins, contudo, os aspectos relacionados à determinação do ponto de colheita e o prolongamento da sua vida útil pós-colheita ainda são bem escassos na literatura. Diante disso o presente trabalho tem por objetivo avaliar a relação entre o estádio de abertura floral das espatas de copo de leite e a sua conservação em solução de pulsing a base de ácido cítrico. Para tanto adotou-se um delineamento experimental inteiramente casualizado em esquema fatorial 3 x 4 x 6; três estádios de abertura floral, quatro concentrações de ácido cítrico e seis tempos de armazenamento com cinco repetições e três hastes por parcela experimental. As análises de qualidade e perda de massa fresca (%) ocorreram a cada dois dias e revelaram interação significativa entre os três fatores analisados (p<0,05). Concluiu-se que o uso de ácido cítrico a 30% mantém a qualidade das hastes florais independente do estádio de colheita. A vida útil das amostras foi de 4, 6 e 8 dias para espatas colhidas totalmente abertas, 1/3 abertas e totalmente fechadas, respectivamente.

The sunflower (Helianthus annuus L.) is an ornamental plant of great acceptance in the market, however, as cut flower has its limited useful life, about 3 to 5 days at room temperature. In order to prolong shelf life and preserve post-harvest quality was evaluated the effect of maintenance solutions on sunflower cv. Oasis for 10 days storage at 25 °C. O experimento foi conduzido em delineamento inteiramente casualizado em arranjo fatorial 5x6, correspondendo a cinco tratamentos/soluções de manutenção (distilled water (control), sucrose, citric acid, gibberellic acid and benzylaminopurine to 5%) and six evaluation times (0, 2, 4, 6, 8 and 10 days). The effect of treatments on fresh mass, inflorescence turgescence, stem curvature, relative petal water content, respiratory rate and carbohydrate content was investigated. The results showed that the solutions with sucrose and gibberellic acid significantly (p<0.05) preserved the quality of the inflorescences as a function of the control of respiratory activity and water absorption, thereby reducing the physiological processes related to senescence. It is recommended to use sucrose 5% as a maintenance solution due to the low cost to producers and consumers.

“…Several formulations of coatings have been developed based on starch that may be obtained from various plant sources, such as cereals, roots and tubers, fruits, and vegetables. Cassava starch has been applied to fruits, vegetables, some flowers, and roots due to its ability to form films without the addition of additives (Sanches et al, 2016). Coatings have had satisfactory effects in cherries, inhibiting peroxidase activities, preventing fruit browning, and delaying lipid peroxidation while maintaining membrane integrity (Pasquariello et al, 2015).…”

“…Coatings have had satisfactory effects in cherries, inhibiting peroxidase activities, preventing fruit browning, and delaying lipid peroxidation while maintaining membrane integrity (Pasquariello et al, 2015). The use of cassava starch-based films (4%) in ornamental ginger inflorescences maintains a better appearance of the flowering stems (Sanches et al, 2016).…”

Starch-based films for Red Torch ginger inflorescences postharvest conservation

et al. 2023

Different products have been tested to increase the vase life of cut flowers after harvest such as the biodegradable films. These products have been used in fruits since the application on the surface may provide the modification of the atmosphere around it, although, there is no information for flowers. The objective was to evaluate the effectiveness of cassava starch films as a postharvest product for Red Torch Ginger inflorescences. On the first experiment, different starch concentrations in the solution were tested and in the second experiment starch, concentrations with plasticizers and adjuvants were evaluated. The application of the biodegradable film in Red Torch stems acted as a barrier to the gases, as observed by their water absorption rate and the maintenance of fresh weight, maintaining postharvest quality up to Day 6. The visual quality was better in the inflorescences treated with 6% starch and in the films without additives. The use of 6% starch films led to lower contents of hydrogen peroxide and lipid peroxidation and higher levels of primary-metabolism macromolecules up to Day 6, delaying senescence and increasing postharvest durability. The addition of glycerol plasticizer to the different film concentrations improved the film resistance characteristics. It is recommended the use of films based on cassava starch at a concentration of 6%. The use of the adjuvant is not essential since it changed the film’s characteristics, leaving it less transparent and more viscous, hindering drying.
