Resumo: | Floral opening stage during harvest and use of postharvest techniques, such as inflorescence coating with carnauba wax, may influence quality maintenance for commercialization. The aim was to evaluate the carbohydrate content of torch ginger inflorescences harvested at two different opening stages and treated with different concentrations of carnauba wax. The inflorescences were harvested with semi-open (basal bracts beginning their expansion process) and open bracts (fully expanded basal bracts and opening of the smaller bracts on interior of the inflorescence) and received the application of carnauba wax at concentrations of 0.75%; 1.5% or 3.0%, in addition to a control treatment, without wax application. After the treatment, the floral stems were maintained at 16 and 21 oC for 20 days. During the storage period, five bracts samples (external and internal bracts separately - in open inflorescences, external and internal bracts together - in semi-open inflorescences) were carried out every three days for evaluation of total soluble sugars and starch content. Contents of total soluble sugars and starch differed between the different types of bracts collected and throughout the storage period evaluated, and could indicate a remobilization of reserves. The concentration of 3.0% carnauba wax induced higher total soluble sugar content. However, this content does not affect the longevity of torch ginger at the two evaluated floral opening stages. |

Assim, objetivou-se avaliar o conteúdo de carboidratos em inflorescências de bastão-do-imperador colhidas em dois diferentes estádios de abertura e tratadas com diferentes concentrações da cera de carnaúba. As inflorescências foram colhidas com brácteas semiabertas (brácteas basais iniciando seu processo de expansão) e abertas (brácteas basais totalmente expandidas e abertura das brácteas menores do interior da inflorescência) e receberam a aplicação de cera de carnaúba nas concentrações 0,75%; 1,5% ou 3,0%, além de um tratamento controle, sem aplicação da cera. Após o tratamento, as hastes florais foram mantidas a 16 e 21 o C por 20 dias. Ao longo do período de armazenamento realizaram-se cinco amostragens de brácteas (brácteas externas e internas separadamente – em inflorescências abertas; brácteas externas e internas em conjunto – em inflorescências semiabertas), a cada três dias para avaliação dos teores de açúcares solúveis totais e amido. Os teores de açúcares solúveis totais e amido diferiram entre os diferentes tipos de brácteas coletadas e ao longo do período de armazenamento avaliado, podendo indicar uma remobilização de reservas. A concentração de 3,0% de cera de carnaúba proporcionou um maior teor de açúcares solúveis totais, entretanto esse teor não interfere na longevidade do bastão-do-imperador nos dois estádios de abertura floral avaliados.International Society for Horticultural Science (ISHS)2019-06-11T18:44:36Z2019-06-11T18:44:36Z2018-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMATTOS, D.
