“…The flowering of adult plants was influenced by several factors, such as fertilizer, light duration and quality, temperature, and plant growth regulators (PGRs), which affect flower induction, development, and flower characteristics. Flower diameter as well as the inflorescence length increased in response to increasing nitrogen and potassium fertilization during the adult vegetative stage in Cymbidiums grown at low light intensity and artificially induced inflorescence, while flower quality decreased in those grown at high light intensity [22]. Barman et al [23] maintain that water-soluble fertilizers significantly affected the growth and reproductive stages of Cymbidiums.…”

Cymbidium is an economically important genus in the orchid family (Orchidaceae) that has a pronounced medicinal and ornamental value. Medicinally, the plant is employed as a tonic to treat weakness in chronic diseases, dizziness, eye problems, burns, and wounds, etc. Cymbidiums are highly prized for their graceful flowers and sweet fragrance and are among the top ten most popular cut flowers. They are one of the most important commercial orchid groups and account for 3% of cut flowers in floriculture. Some orchid species in this genus are particularly threatened by excessive harvesting, so conservation measures are needed. Several enthusiastic organizations (e.g., The Cymbidiums Society of America, The Cymbidiums Club in Australia, The Golden Gate Cymbidiums Society, Alameda, CA, etc.) are dedicated to propagating, conserving, promoting, appreciating, and disseminating information about these beautiful and charming orchids. Through organogenesis (direct and indirect) and somatic embryogenesis, extensive propagation techniques for Cymbidiums have been developed to create protocols for synthetic seed production leading to large-scale propagation and long-term ex situ and in vitro conservation. This review highlights the medicinal uses, flower trade, conservation, and massive propagation techniques of Cymbidium orchids.

“…In our previous study, NI in winter during 2 years promoted vegetative growth and consequently hastened flowering within 2 years compared to the 3-4 years of general cultivation with natural light conditions in Cymbidium 'Red Fire' and 'Yokihi' (An et al, 2012;Kim et al, 2011). However, no experiments were performed regarding summer environment controlling methods of Cymbidium flower induction and development in commercial greenhouses.…”

“…Different species of orchids exhibit sensitivity to daylength in various ways, and yet small changes in daylength are critical for the growth and flowering of plants in the genera Cattleya, Dendrobium, and Phalaenopsis (Bhattacharjee, 1979). Cattleya ladiata and Zygopetalum Redvale 'Fire Kiss' flowered under short-day (SD) (Lopez and Runkle, 2005), while artificial lighting during the middle of the night (night interruption, NI) promoted the growth and/or flowering of Cymbidium 'Red Fire' and 'Yokihi' (An et al, 2012;Kim et al, 2011) as well as some herbaceous long-day (LD) plants (Blanchard and Runkle, 2010;Oh et al, 2008;Yamada et al, 2008).…”

Growth and flowering of Cymbidium 'Red Fire' and 'Yokihi' plants were examined in a greenhouse with cooling systems in summer, and with night interruption (NI) lighting in winter as a forcing culture system. The greenhouse was divided into two sections with separate cooling controls during the summer season. One section was cooled by a mist system (mist), while the other section was cooled by a shade screen (shade). During the winter, the greenhouse was redivided into three sections within each cooling system. Plants were grown with NI either at a low light intensity of 3-7 µmol･m -2 ･s -1 (LNI) or a high light intensity of 120 µmol･m -2 ･s -1 (HNI) using high-pressure sodium lamps during the 22:00-02:00 HR. The control plants were grown under 9 h short-day condition. NI for 16 weeks and cooling for 9 weeks were employed twice during the 2 years of the experimental period. The air temperature was approximately 2°C lower in the mist than in the shade and the relative humidity was 80 ± 5% in the mist compared to 55 ± 5% in the shade. The daily light integral in the mist section was 48% higher than in the shade section. The time from initial planting to flowering pseudobulb emergence decreased with both LNI and HNI for both cultivars, regardless of the cooling treatments. Under NI conditions, however, between 60% and 100% of plants of both cultivars flowered in the mist, whereas no or 20% of 'Red Fire' or 'Yokihi' plants, respectively, flowered in the shade treatment over 2 years. Plants grown under the mist had bigger pseudobulbs than those grown in the shade under both NI treatments. These results show that commercial use of NI in winter and a mist cooling system in summer would decrease crop production time to 2 years and increase profits in Cymbidium forcing culture.
