“…Flower stems stored for 2 days at 1 °C remained more turgid, compared to those maintained for 6 days at the same temperature (Figure 3). Plants maintained in cold chambers for long periods show an increase in ethylene production rates, as well as increased membrane permeability, leading to flower senescence (FARAGHER et al, 1984). Similar results were observed in calla lily inflorescences removed from the cold chamber at 4 °C after 10 days of storage (ALMEIDA et al, 2008).…”

The loss of commercial quality during storage and transportation of roses is one of the factors that reflect on production costs, leading producers to preventively apply harmful chemicals, mainly to hamper Botrytis cinerea development and reduce further losses. An alternative to increase flower longevity without contaminating the environment with harmful chemicals is the use of natural products, such as essential oils, which have fungistatic and insecticide properties, as well as low toxicity. The objective of this study was to evaluate the effect of essential oils on the vase life of Rosa cv. Avalanche: 12 treatments were tested, resulting from the combination of 5 types of essential oils plus the control in two cold storage periods (2 to 6 days) at 1 °C, 90-95% RH. The essential oils tested were eucalyptus, cinnamon, lemongrass and peppermint (1%), clove (0.1%), plus a control with distilled water. Application was made by spraying the flower buds. After storage at low temperatures, the flower stems were kept in a room (16 °C, 70% RH) during 10 days for evaluation. Flower stems stored for 2 days in a cold chamber showed better means for darkening, turgor and bent neck, as well as a lower weight loss by the stems. The application of lemongrass essential oil at 1% caused burns on the petals, compromising quality and pot life. The essential oils of peppermint and eucalyptus allowed flower quality maintenance until the 10th day of evaluation. It is possible to conclude that post-harvest spraying with peppermint or eucalyptus essential oil at 1%, combined with cold storage for 2 days, provided greater longevity and quality for cv. Avalanche roses.

Uma das alternativas para aumentar a durabilidade das flores de forma ecologicamente correta é a utilização de produtos naturais, como os óleos essenciais, que apresentam características fungistáticas e inseticidas, além de baixa toxicidade. O objetivo deste trabalho foi avaliar o efeito da aplicação em pós-colheita de diferentes óleos essenciais na durabilidade de hastes de Rosa cv. Avalanche em 2 períodos de armazenamento em câmara fria. Foram testados 12 tratamentos resultantes da combinação de 5 tipos de óleos essenciais mais a testemunha associados à dois períodos de armazenamento refrigerado, 2 e 6 dias, sob 1 ºC e 90-95% UR. Foram testados óleos essenciais de: eucalipto, canela, capimlimão e hortelã-pimenta (a 1%), cravo-da-índia (a 0,1%), e a testemunha, com água destilada. A aplicação foi feita por meio da pulverização nos botões florais. Após o armazenamento refrigerado, as hastes florais foram mantidas em uma sala ...

“…The process of rose flower bud development and subsequent flower opening is irreversible petal growth and reflection in which existing cells expand and fresh and dry weights (DW) increase Evans & Reid 1988;Faragher et al 1984). In Gaillardia × grandiflora, cell division of the petals seems to stop at a much early stage of flowering, with no increase in the number of abaxial epidermal cells (Koning 1984).…”

Roses are the most important crop in the floriculture industry and attract both pollinators and human admirers. Until now, a lot of research focusing on postharvest physiology including flower senescence has been conducted, leading to improvement in vase life. However, few studies have focused on the physiology of petal growth, the perception of light by petals, and the relationship between petal growth and environmental conditions. Regarding roses, whose ornamental value lies in the process of blooming from buds, it is also important to understand their flowering mechanisms and establish methods to control such mechanisms, as well as focus on slowing the aging process, in order to achieve high quality of postharvest cut roses. Elucidation of the mechanisms of rose flower opening would contribute to enhanced quality and commercial production of floricultural crops as well as greatly advance basic scientific knowledge regarding plant biology. In this review, we describe the progress and future prospects in the study of petal growth physiology of cut roses.

“…In the Asiatic hybrid lily (Lilium hybrid), flower opening proceeded irregularly if it was kept in continuous darkness, indicating the importance of changing from light to darkness for the timing of flower opening (Bieleski et al, 2000). Rose-flower opening is a process of irreversible petal growth and reflection in which existing cells expand and fresh and dry weights increase Reid, 1986, 1988;Faragher et al, 1984). In hybrid tea rose, flower opening showed a diurnal rhythm under a 12 h photoperiod, but proceeded irregularly if it was kept in continuous darkness Reid, 1986, 1988).…”

Some flowers including rose open in a rhythmic fashion during specific times of the day. We used time-lapse cinematography to understand the mechanism of rhythmic opening and perception of light in cut rose flowers. Cut rose flowers exposed to a 12 h light/12 h dark photoperiod started opening shortly before the light period had begun and stopped during the light period even when their leaves were removed, indicating that petals and/ or sepals perceive light and synchronize flower opening to photoperiods. This rhythmic opening could be seen in constant darkness even though the time of flower opening shifted to an earlier point in constant darkness compared with the 12 h photoperiod, but it was not observed in constant light. We also evaluated the effect of exposing cut flowers first to a 12 h photoperiod and then shifting them to an 18 h photoperiod. During the 12 h photoperiod, flower opening started shortly before the light period had begun and stopped during the light period, while in the 18 h photoperiod, it proceeded in the middle of the dark period. These results suggested that changes of light to darkness or vice versa were important signals for the start and maintenance of rhythmic flower opening. In addition, we found that even a petal removed from a rose flower showed rhythmic growth when exposed to a 12 h light/12 h dark photoperiod, showing that petals could perceive light and synchronize their growth to the photoperiod.
