Conservação pós-colheita de flores

Abstract: Após a colheita de flores, processos fisiológicos e fatores ambientais aceleram sua deterioração, entretanto o aumento da vida útil pode ser obtido com a utilização de adequada tecnologia de conservação. Esta revisão analisa as causas da deterioração pós-colheita e aborda as principais medidas e técnicas para aumentar o período de conservação e retardar a senescência de flores de corte ou de vaso.

“…The lisianthus pre-exposed in cold chamber (9 ± 2 °C) for 24 hours (Tables 2, 4 and 6) had higher carbohydrate levels during the storage period than those stored at room temperature (24 ± 2 °C) (Tables 1, 3 and 5). Low temperatures decrease respiration and transpiration, slow sugar reserves degradation, reduce ethylene production, prolong flowers durability (SONEGO and BRACKMANN, 1995), and consequently slows down degradation of carbohydrates (Srivastava et al, 2015). Oncidium varicosum 'Samurai' inflorescences kept at 5 and 10 ºC maintain the soluble carbohydrate contents constant, indicating that carbohydrates were little used during the senescence process and resulted in a longer vase life (MATTIUZ et al, 2010).…”

“…The development of postharvest technology should include the evaluation of different storage alternatives used to achieve a gain of days in the flower conservation period (Sonego & Brackmann, 1995). The aim of the present study was to evaluate the effect of the cold storage of flowering stems of Heliconia bihai cv.…”

“…A queima da bráctea é um processo natural que ocorre com o amadurecimento, desidratação e a senescência da inflorescência; a senescência é desencadeada sobremaneira pela síntese do etileno (conhecido como hormônio do estresse). A presença do Si diminui a perda de água reduzindo, por conseguinte, a produção de etileno (Sonego & Brackmann, 1995;Brackmann et al, 2008). Paulino et al (2013) também constataram que a queima de bráctea decresceu de forma linear com o aumento da dose de Si; assim, o silício contribui para manutenção da qualidade das flores através da redução da senescência.…”
