Alstroemeria flowers have shown great importance in the world trade of cut flowers due mainly to its beauty and wide variety of colors. However, the durability of its inflorescences is usually hampered by the rapid yellowing of the leaves, which impairs their decorative quality. Cut flowers require the use of technologies to improve postharvest quality and floral longevity. This research aimed to study the postharvest conservation of inflorescences of Alstroemeria cv. Ajax at different storage temperatures. Floral stems were placed in containers with distilled water and stored at four temperatures (4, 8, 12, and 22ºC) for 12 days. The following analyses were performed: fresh mass variation, respiratory activity, relative water content, soluble and reducing carbohydrate contents, polyphenol-oxidase and peroxidase enzymes, pigments (anthocyanin and carotenoids), and longevity. The experiment was conducted in a completely randomized design, the results were submitted to analysis of variance (ANOVA), and the effect of treatments submitted to F-test. Significant differences were compared using the least significant difference (LSD) at 95% confidence interval (p ≤ 0. 05). The temperatures of 8 and 12ºC were effective in maintaining the postharvest quality of inflorescences during storage period, as they remained turgid due to transpiration reduction caused by low temperatures, and longevity reaching 46 and 22 days, respectively.

The effect of STS and 1-MCP on the postharvest quality of carnation and rose cut flowers was studied. Cut flowers of Dianthus c..aryophyllus L. cv. Asso and Rosa hybritia cv. Baroness were treated with silver thiosulfate (STS) at 0.4 mM with sucrose at 50 g 1-t and 1-methylcyclopropene ( I -MCP) at 0.5 g m-3 for 611. Pretreatment with STS and 1-MCP significantly extended the vase life and minimized the % loss of initial weight of carnation and rose cut flowers comparing to the untreated control. The two chemicals applied inhibited the chlorophyll degradation and carbohydrate loss and hence, significantly improved the postharvest quality of carnation and rose cut flowers comparing to the control. Ethylene production by cut flowers was inhibited as a result of using these chemicals. In general, there were no differences between STS and (-MCP but the later does not have the heavy metal implications of STS treatment, and hence, using 1-MCP pretreatment for extending the vase life of carnation and rose cut flowers was recommended.

Abstract Accurate quality classification is one of the requirements of the flower market, which is becoming increasing more sophisticated and demanding. However, there is a lack of information regarding how such classification is performed, and it is often conducted in a less empirical and more subjective way. Therefore, this work aimed to compare the efficiency of personal classification (in-person) and using digital images to determine the quality of anthurium cv. Tropical (Anthurium andraeanum Lind.). Three experiments were performed regarding the recording of the images and the display mode of the images and comparing three methods of classifying postharvest quality of anthurium. It was concluded that measurements of colorimetric parameters can be performed anywhere on the spathe, but the period in which the parameters are measured does affect. Evaluators differ in the thoroughness with which they assign grades, and there is no need for prior knowledge to assess quality using images. The L* parameter measured by the colorimeter presented higher correlation with the evaluation of postharvest quality of Anthurium andraeanum Lind. ‘Tropical’. Classification by images can be performed using different electronic devices, and in-person classification is more rigorous than classification conducted using digital images.
