“…It is because lower temperatures reduce transpiration rate, thereby reducing the loss of water (Vilas Boas, 2000). These findings are following Santos et al (2012), who observed a gain of fresh mass in Epidendrum ibaguense flowers placed in water and kept at 10ºC.…”

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 example, in inflorescences of heliconia 'Golden Torch', senescence anticipation occurs only when high doses of ethephon are used (100 and 1,000 mg L -1 ); therefore, the application of ethylene inhibitors in the postharvest of this species is not justified (SOUZA et al, 2014). However, for the tropical orchid Epidendrum ibaguense, the use of ethylene inhibitors is recommended (SANTOS et al, 2012).…”

The climatic characteristics of the country favor the cultivation of tropical flowers. The continued expansion of this market is due the beauty, exoticit nature and postharvest longevity of flower. However, little is known about the postharvest of tropical plants. Therefore, this paper provides information on harvest, handling and storage of cut tropical plants. Keywords: postharvest, storage temperature, conditioning solution. RESUMO Manutenção da qualidade de plantas tropicaisAs características climáticas do país favorecem o cultivo de flores tropicais A continua expansão deste mercado é devido à beleza, exoticidade e longevidade pós-colheita das hastes florais. No entanto, pouco se sabe sobre a pós-colheita de plantas tropicais. Portanto, este artigo fornece informações sobre colheita, manuseio e armazenamento de plantas tropicais cortadas.

“…The previous findings were documented by Hutchinson et al, (2003) who suggested that STS and sucrose can improve tuberose vase life and floret opening through improvement of the water balance. Furthermore, Santos et al, (2012) declared that vase life of Epidendrum ibaguense spikes was increased to 6.5 days when pulsed with 2 mM STS for 30 min. The STS applied before cold storage reduced the rate of flower abscission and improved the ratio between transpiration and water uptake.…”

and 2013 seasons to explore the effect of silver thiosulphate solution (STS) applied as foliar spray or as immersing solution for 10, 20 and 30 minutes (control spikes were immersed in distilled water), cold storage at 5 C, vertically or horizontally for 2 or 4 days, beside control treatment in which spikes were kept at room temperature and their interactions on water relations, longevity and quality of Gladiolus hybridus cv. "White Prosperity" cut spikes. After each treatment, the bases of spike stems were held in 10 % sucrose solution till the end of the experiment. The obtained results showed that STS pulsing treatments caused a significant increment in the amount of water uptaken by cut Gladiolus spikes, and significantly decreased, the amount of water loss compared to control in most cases of the two seasons. These treatments were also improved floret diameter, vase life, spike fresh and dry weights, dry weight %, opening %, leaf content of chlorophyll a, b and reducing sugars % in the leaves petals, and decreased wilting %, and carotenoids content in the leaves and total sugars % in the leaves and petals. However, the prevalence was for immersing in STS solution for 10 min treatment, which gave the best values in most previous characters with few exceptions in both seasons. Storage at room temperature or at 5C, vertically or horizontally for 2 or 4 days alternated improving means of previous characters with the mastery of horizontal cold storage treatment for 2 days, which recorded the best results in most cases. The interaction treatments also induced a marked improvement in most measurements, but the dominance was for the combining between immersing in STS solution for 10 min. and horizontal cold storage for 2 days, as this combination gave the best water relations, the longest vase life and the highest quality compared to the other individual and combined treatments. Accordingly, it is recommended to immerse the cut spikes of Gladiolus cv. "White Prosperity" in STS solution for 10 min and then holding them in 10 % sucrose solution at room temperature for local marketing or storage them after immersing in STS solution, horizontally for at least 2 days at 5 C for shipment abroad.
