“…In cut orchid flowers of Epidendrum ibaguense, treatment with 1-MCP increased longevity by reducing flower abscission and wilting (FINGER et al, 2008). Fumigation with 1-MCP has been effective in blocking the negative effects of ethylene different flowers, including some varieties of roses, geranium, phalaenopsis, diantus, gentian and inflorescences of Oncidium varicosum (SEGLIE et al, 2010;SHIMIZU-YUMOTO & ICHIMURA, 2012;MATTIUZ et al, 2012). In this research, 1-MCP was applied to prevent abscission and yellowing of leaves in potted ornamental pepper cultivar 'Calypso' applied at post production shelf stage.…”

Longevidade de hastes florais de Oncidium baueri mantidas em soluções conservantes

Orchids have been gaining prominence in the cut flower market due to the exoticism and the singular beauty of its flowers. However, techniques which help to keep the floral quality are needed, since the commercial success is tied to the flowers longevity after cut. Thus, the aim of this study was to evaluate preservative solutions on postharvest longevity of Oncidium baueri floral stems. Floral stems, with 60 cm of length and 90% of open flowers were submitted to pretreatment in a pulsing solution, sucrose-based, for 12 and 24 hours, and placed in maintenance solutions containing sucrose and/or Flower®; keeping the control treatment, with distilled water only. These solutions were added with 0.5% of sodium hypochlorite. The evaluation to verify the quality of the flowers was performed daily using a criterion of notes, ranging from 4 to 0. From third day of evaluation, the floral stems submitted to pretreatment with pulsing solution presented statistically lower averages and at the fourth day of evaluation were considered inadequate for marketing. Increased longevity and quality of the flowers can be obtained by keeping the floral stems in distilled water or in maintenance solutions, which are 1% sucrose-based.

“…Agrotec., Lavras, v. 39, n. 4, p. 315-322, jul./ago., 2015 Orchid flowers are very sensitive to ethylene Mayak, 1981), and because ethylene production is an autocatalytic process, larger quantities are produced when flowers are in the presence of senescent flowers. Compounds that can be used to prevent ethylene production in cut flowers include silver thiosulfate, naphthalene acetic acid (Gago;Monteiro, 2012), and 1 methylciclopropene (1-MCP) (Mattiuz et al, 2012a).…”

The orchid Oncidium varicosum is a tropical plant with significant commercial value due to the beauty of its yellow inflorescences. Several authors have observed a reduction in the water content of cut flowers, consequently, wilting and senescence of petals are the main reasons for the termination of the decorative life of cut flowers. In this research, we studied the effects of several chemical compounds on the postharvest life of cut inflorescences of Oncidium varicosum 'Samurai'. These chemicals are as follows: sucrose (5%) plus 8-hidroxiquinoline citrate (8-HQC) (100 mg L -1 ) plus silver nitrate (AgNO 3 ) (50 mg L -1 ); sucrose (5%) plus citric acid (75 mg L -1 ); quaternary ammonia at 30% (50 mg L -1 ); and sucrose (5%) plus quaternary ammonia at 30% (50 mg L Index terms: Physiology; orchids; flowers; carbohydrates; carotenoids; relative water content. RESUMOA orquídea Oncidium varicosum é uma planta tropical com destacada importância comercial, em razão da beleza de suas inflorescências de coloração amarela. A redução do conteúdo de água de flores cortadas tem sido constatada por diversos autores e, como consequência, o murchamento e a senescência das pétalas são as principais razões para a redução da vida útil de flores cortadas. Na presente pesquisa, foi estudado o efeito de diferentes compostos químicos (sacarose (5%) + 8-hidroxiquinolina (8-HQC) (100 mg L -1 ) + nitrato de prata (AgNO 3 ) (50 mg L -1 ); sacarose (5%) + ácido cítrico (75 mg L -1 ); amônia quaternária a 30% (50 mg L -1 ); sacarose (5%) + amônia quaternária a 30% (50 mg L -1 ) sobre a vida pós-colheita de inflorescências cortadas de Oncidium varicosum 'Samurai'. Os maiores valores médios do conteúdo relativo de água, carboidratos redutores e açúcares solúveis foram registrados nas flores em solução de sacarose 5% + 8-HQC (100 mg L -1 ) + AgNO 3 (50 mg L -1 ). A redução da intensidade da cor foi mais acentuada, após 12 dias de vida pós-colheita e o conteúdo de carotenoides apresentou maior redução para as flores mantidas em água destilada. Os menores números de flores abertas nas inflorescências de Oncidium, aos 12 e 15 dias de vida de vaso foram observados nas hastes mantidas em água destilada e nas duas soluções com amônia quaternária, ou seja os outros tratamentos favoreceram a antese. As flores de Oncidium tratadas com sacarose+HQC+AgNO 3 obtiveram maior número de flores abertas nas inflorescências, e alcançaram maior longevidade floral (22 dias).
