“…We used as core scale ranging from 5 to 1, wherein, score 5 (maximum): 100 closed and turgid flowers, 100 green leaves, and 100% attached anthers; score 4: 75 opened and turgid flowers, 75 green leaves, and 75% attached anthers; score 3: 50 opened and turgid flowers, 50 green leaves, and 50% attached anthers; score 2: 25 opened and turgid flowers, 25 green leaves, and 25% attached anthers; score 1:100% opened and wilted flowers, and fully yellowed leaves, and absence of anthers. This method was described by Galati et al (2015), who considered a score3 as trade limiting.…”

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.

“…For this evaluation was given a rating scale ranging from 5 to 1, where: Note 5 (maximum score): the flowers were 100% closed and 100% turgid, the leaves were 100% green, and had 100% of the anthers; Note 4: 75% of flowers opened and 75% turgid, leaves 75% green and had 75% of the anthers; Note 3: the flowers were 50% opened and 50% turgid, the leaves 50% green and 50% had anther; Note 2: 25% of flowers opened and 25% turgid, 25% of green leaves and had 25% of the anthers; Note 1: 100% of flowers opened and wilted and the leaves completely yellowed, and there was no presence of anthers on the flowers, according to the methodology described by Galati et al (2015). The completion of this evaluation occurred when the flowers presented darkening, abscission, withered petals and yellowing of the leaves.…”

Postharvest conservation of alstroemeria ‘ajax’ using 1-methylcyclopropene

et al. 2017

Cut flowers deteriorate quickly and require postharvest technologies to increase their durability, which is usually around 8 days. Due to the scarce information related to postharvest physiology of Alstroemeria cut flowers, this study aimed to verify the best dose of 1-methylcyclopropene (1-MCP) to the postharvest conservation of inflorescences of Alstroemeria cv. Ajax, considering the factors associated with floral senescence and loss of the decorative life. The stems were submitted to four doses of 1-MCP (0; 100; 250; 500 ppb), then placed in containers with distilled water and stored at room temperature (22 ºC). The treatments were performed in triplicate containing three stems per replicate. The evaluations were performed every three days for a total of 12 days of storage. An F test was conducted, and the means were compared by the Tukey test (p≤0.05). Among the applied treatments the dose of 500 ppb of 1-MCP reduces the loss of water of the stems of alstroemerias during the storage period, keeping the petals turgids and the levels of carotenoids and anthocyanins high, however, this was not enough to keep the decorative quality of the flowers, once the 1-MCP did not solve the problems of yellowing of the leaves and floral openning, which are important characteristics for its commercialization.Index terms: Ethylene; longevity; pigments; enzyme activity. RESUMOAs flores de corte se deterioram muito rapidamente e necessitam de tecnologias pós-colheita para aumentar a durabilidade, que é normalmente em torno de 8 dias. Devido às escassas informações relacionadas à fisiologia pós-colheita de flores de Alstroeméria, a presente pesquisa teve como objetivo verificar qual a melhor dose de 1-metilciclopropeno (1-MCP) na conservação pós-colheita de inflorescências de Alstroemeria cv. Ajax, considerando os fatores associados à senescência floral e perda da vida decorativa. As hastes foram submetidas a quatro doses de 1-MCP (0; 100; 250; 500 ppb), posteriormente foram colocadas em recipientes com água destilada e armazenadas em temperatura de ambiente (22 ºC). Os tratamentos foram realizados em triplicata contendo três hastes por repetição. As avaliações foram realizadas a cada três dias perfazendo um total de 12 dias de armazenamento. Foi realizado um teste de F, e as médias comparadas pelo teste de Tukey (P≤0,05). Entre os tratamentos aplicados a dose de 500 ppb de 1-MCP reduziu a perda de água das hastes de alstroeméria durante o período de armazenamento, mantendo as pétalas túrgidas e os níveis de carotenoides e antocianinas altos, entretanto, isso não foi suficiente para manter a qualidade decorativa das flores, uma vez que o 1-MCP não resolveu os problemas de amarelecimento das folhas e abertura floral, que são importantes características para sua comercilização.Termos para indexação: Etileno; longevidade; pigmentos; atividade enzimática.

“…Each species or cultivar responds differently to the sucrose concentration [55]. Chemical pulsing treatments include silver thiosulfate (STS) [18,61,62], hydroquinone (HQ) [34,58,63], 8-hydroxyquinoline sulfate (8-HQS) [39], silver nitrate (AgNO 3 ) [64], aminooxyacetic acid (AOA) [65,66], calcium dichloride (CaCl 2 ) [67], cobalt chloride (CoCl 2 ) [60], aluminum sulphate (Al 2 (SO 4 ) 3 ) [68], chlorine dioxide (ClO 2 ) [69], and benzyladenine (C 12 H 11 N 5 ) [70,71]. High concentrations of silver nitrate solution have been used in studies on the pulsing treatment of many cut flowers, including gerbera [72], gladiolus [73], chrysanthemum [74], carnation [74,75], Persian buttercup [64], herbaceous peony [63], and rose [76].…”

Cut flowers have become an export income in the global floriculture market. They have multiple uses, such as for home beautification, in ceremonies (including weddings and funerals), and as symbols of love, appreciation, respect, etc., in humane society. Each type of cut flower has a different vase life and the longevity of their freshness is linked to preharvest, harvest, and postharvest tools and conditions. The postharvest quality and vase life must be considered in order to obtain the desirable qualities of cut flowers, and factors that affect this are important in the floral industry. The use of floral preservative solutions is good practice for prolonging the vase life of cut flowers. Currently, the eco-friendly solutions, which are used as floral preservatives for extending cut flower vase life, have been discovered to be a low-cost and organic alternative as compared to chemical solutions. However, there are certain problems associated with the use of chemical and eco-friendly solutions. In this review, we summarize several potential approaches to improve flower vase life and discuss the best choices for holding-preservative-solution practices.
