ABSTRACT:The ornamental Ginger is a tropical plant widely used in gardens or as a cut flower in floral arrangements; however, there are no studies on its post-harvest conservation associated with the stem cutting size and the use of cassava starch. Thus, this study aims to determine the optimal stem cutting size and the effect of cassava starch biofilms in order to increase shelf life. The stems were collected in three sizes: 10, 15 and 20 cm and subjected to five treatments with cassava starch: control, 2, 4, 6 and 8%. Authors evaluated every four days fresh weight loss and quality of inflorescences. The cutting size, when associated with the different cassava starch concentrations, showed different values over the storage time. The stems harvested with 10 cm had a lower percentage of weight loss and higher quality score. The concentration of 4% starch reduced weight loss and preserved the quality of stems regardless of the cutting size and it is, therefore, the recommended concentration for the conservation of ornamental ginger by favoring commercial life of up to 16 days. Keywords:Zingiber spectabile, cassava starch, tropical flowers, post-harvest.Tamanho do corte da haste e do biofilme na longevidade de gengibre ornamental RESUMO: O gengibre ornamental é uma planta tropical muito utilizada em jardins ou como flor de corte em arranjos florais, todavia, não se tem estudos sobre sua conservação pós-colheita associada ao tamanho de corte da haste e o uso da fécula de mandioca. Assim, o presente trabalho tem por objetivo determinar o tamanho ideal de corte das hastes e o efeito do biofilme de fécula de mandioca visando o aumento da vida de prateleira. As hastes foram colhidas em três tamanhos: 10, 15 e 20 cm e submetidas a cinco tratamentos com fécula de mandioca: Controle, 2, 4, 6 e 8%. Avaliou-se a cada quatro dias a perda de massa fresca e a qualidade das inflorescências. O tamanho do corte quando associado as diferentes concentrações de fécula de mandioca apresentaram valores diferentes ao longo do tempo de armazenamento. As hastes colhidas com 10 cm apresentaram menor percentual de perda de massa e maior índice de qualidade. A concentração de fécula a 4% reduziu a perda de massa e preservou a qualidade das hastes independente do tamanho de corte avaliado sendo, portanto a recomendada para a conservação de gengibre ornamental por favorecer vida útil comercial de até 16 dias.

Unemoto et al (2011), em estudo pós-colheita com bastão-do-imperador, observaram variações na massa fresca entre 11% a 30%, ao longo de 15 dias de avaliação, sendo que nas hastes tratadas apenas com água ocorreu uma perda de 16%. A perda excessiva de massa fresca (água) pela transpiração e/ou obstruções dos vasos do xilema, causam murcha e, consequentemente, redução da durabilidade pós-colheita.…”

RESUMOAs espécies tropicais apresentam grande importância no mercado de flores, mas informações sobre colheita e procedimentos pós-colheita ainda são limitados. Para a maioria das espécies tropicais, existem poucas informações sobre soluções a serem utilizadas para condicionamento ou manutenção após a colheita. Assim, objetivou-se avaliar a durabilidade e qualidade pós-colheita de hastes florais de bastão-do-imperador em concentrações de sacarose na solução de condicionamento e diferentes estádios de abertura floral. Hastes florais foram colhidas no início da manhã e tratadas com solução de condicionamento com sacarose nas concentrações 0 (controle), 10, 20, 30% por 24h, nos três estádios de abertura floral: inflorescências com as brácteas 1/3, 2/3 ou totalmente abertas. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 4x3x6, com 3 repetições em parcela subdividida no tempo. As avaliações foram realizadas em intervalos de 3 dias, determinando-se a massa fresca das hastes florais e avaliação de qualidade das inflorescências por meio de notas, em escala de 0 a 4. Observou-se que a durabilidade comercial das hastes florais é maior (10 dias) quando as inflorescências são colhidas com 1/3 das brácteas abertas. Recomenda-se a realização de condicionamento em hastes florais de bastão-do-imperador com concentração de 20% de sacarose por 24h para inflorescências colhidas com 1/3 e 2/3 das brácteas abertas.

ABSTRACT Developmental stage and pulsing in inflorescences of torch gingerTropical species are very important in the flower market, but information in harvest and postharvest procedures are not enough. There is not enough information on pulsing or holding solutions for most tropical species. The objective was to evaluate the durability and quality of postharvest torch ginger flower stems (Etlingera elatior) at sucrose concentrations in pulsing solution and different flower opening stages. Flower stems were harvested early morning at three flower opening stages: inflorescences with 1/3, 2/3 and completely open bracts, withal the stalks were pulsed with sucrose solution at concentrations of 0 (control), 10, 20, and 30% for 24h. Experimental design was completely randomized in a 4x3x6 factorial with 3 replications in a split plot in time. Evaluations were performed every 3 days, determining the fresh weight of flowers and assessing inflorescence quality through scores on a 0-4 point scale. Commercial vase life of stalks is longer (10 days) when inflorescences are harvested with 1/3 bracts opened. It is recommended to carry out pulsing in torch ginger flower stems with concentration of 20% sucrose for 24h for inflorescences harvested with 1/3 or 2/3 of the bracts opened.

“…de Araújo et al (2018) proposed that cultivar IAC 41 and IAC Camburi were chosen as the suitable cultivars for the breeding program based on their flower appearance and vase life where 8 and 5 days were observed, respectively. On a positive note, application of 1-Methylcyclopropene (1-MCP) and Florissant® were reported to be successful in prolonging the durability of the blooming inflorescence up to five days (Bayogan & Gratuito, 2015;Unemoto, de Faria, Takahashi, de Assis, & Lone, 2011).…”

Etlingera elatior or torch ginger is a species under the Zingiberaceae family, primarily distributed in tropical forests and humid, shady places. It is a coarse herb often growing in large colonies, characterized by elongated leafy stems up to 5 m height arising from underground rhizomes. It is known as kantan in Malaysia and kecombrang in Indonesia. The inflorescence is famous as an ingredient in Malay, Indonesian and Thai dishes. The extract from its stem is used to reduce swelling, and post-partum women use the leaves while the fruits are used to treat earache, diarrhea, coughs, and mouth sores. Because it has a beautiful appearance, it is also widely marketed as a promising floriculture and horticulture plant. Recently, the rising demand from customers for the versatility and durability of cut flowers has made farmers and the horticulture industry search for new cultivars. Thus, researchers are keen to generate cultivars with various colors, shapes, yields, and longer vase life. This could be done through different techniques such as intensive germplasm collection, hybridization programs, and plant biotechnology techniques. Towards achieving these aims, this review provides current insight on E. elatior from botanical, physiological growth, breeding, taxonomy, ecology, commercial potential, postharvest, medicinal, and food nutritional aspects.
