“…It also protects cardiac cells by reducing the release of lactate dehydrogenase from H9c2 cardiomyocytes exposed to oxidative stress [14]. Isovitexin, on the other hand, possesses effective anti-oxidant, anti-inflammatory, and anti-neoplastic properties [15] and accumulates in the tissues of seedlings exposed to blue light [16,17].…”

This study evaluated the anti-oxidant activity of avicularin and isovitexin from Lespedeza cuneata using 2,2-diphenyl-1picrylhydrazyl (DPPH) and hydroxyl (OH) scavenging assays. The results showed that among the four fractions, the highest OH radical scavenging activity was exhibited by the n-butanol fraction. The DPPH radical scavenging activities of avicularin and isovitexin were higher than 50% at a concentration of 100 μg/mL. Moreover, one hundred micrograms per liter of avicularin and isovitexin exhibited effective anti-oxidant activity, with the OH radical scavenging rates being 87.54 and 91.48%, respectively. These results suggest that Lespedeza cuneata would be useful anti-oxidant agents from natural sources.

“…Para a obtenção de qualidade fitoquímica, fatores do ambiente de cultivo in vitro devem ser otimizados, como a composição espectral da luz. Em laboratórios de micropropagação, lâmpadas fluorescentes brancas ainda são as mais utilizadas, no entanto, os diodos emissores de luz (LEDs) têm sido aplicados com sucesso [4].…”

Os objetivos deste trabalho foram investigar a influência da qualidade da luz no crescimento e no acúmulo de constituintes voláteis de Mentha spicata cultivada in vitro. Segmentos nodais de plântulas já estabelecidas foram mantidos sob lâmpadas fluorescentes e diodos emissores de luz (LEDs) com as regiões espectrais nas cores verde, amarelo, vermelho, azul e branco, e nas combinações entre vermelho e azul (1:1; 2:2 e 2:1). Após 45 dias, parâmetros de crescimento, área foliar, índices de crescimento, pigmentos fotossintéticos e análise da composição química volátil de folhas por headspace – CG/FID foram avaliados. A combinação 1:2 proporcionou maiores biomassas seca de folhas, raiz e total. As plântulas dos tratamentos verde, amarelo, fluorescente e vermelho apresentaram características de estiolamento. Em relação à composição química volátil, os constituintes majoritários α-pineno, sabineno, β-pineno, mirceno, 1,8-cineol e carvona foram identificados. Plântulas crescidas sob LEDs verde e amarelo resultaram maior acúmulo de carvona. Assim, este estudo contribuiu para o entendimento das alterações causadas pela qualidade de luz no crescimento in vitro e na composição química volátil de hortelã. Conclui-se que a micropropagação de Mentha spicata sob LEDs na combinação entre vermelho e azul 1:2 é o mais favorável para o crescimento e teor de carvona e de 1,8-cineol.

“…Phalaenopsis cultivars include interspecific hybrids as well as intergeneric hybrids between the orchid genera Doritis and Phalaenopsis (Dor x Phal), and new Phalaenopsis varieties are being continuously developed by the horticulture industry (Pablo, 2008). The importance of Phalaenopsis orchids to the horticultural industry has raised the issue of how to protect the variety rights or intellectual property rights of new plants (variety, cultivar, or hybrid), as it is easy to reproduce an orchid plant by clonal propagation based on tissue culture (Kwon et al, 2018). However, long-term in vitro propagation of plants results in somaclonal variation, which impedes the creation of true to type plants during clonal propagation.…”

“…However, most of the current cultivars are made in Taiwan and the payment of royalties is becoming a burden. Moreover, flavonoid formation was found to be favored in PLB-derived plantlets under all lighting system (Kwon et al, 2018) and in Phalaenopsis Blume, interspecific and intergeneric hybridization has long been used for breeding superior hybrids (Bolanos-Villegas et al, 2008).…”

A new Phalaenopsis cultivar, 'Yellow Green', was bred at Kangsan Orchid, Korea. The new cultivar has small, deep-yellow flowers with a red lip, and was introduced by artificial crossing of the Phalaenopsis cultivar 'Sogo Pride F-1016' and the Phalaenopsis cultivar 'Tzu Ching Glint'. The elite individual KS-752-1, later named as 'Yellow Green', was selected among 300 individual progenies through over three years (2008)(2009)(2010) of intensive selection for excellent vegetative and flowering characteristics. In the 1st (2011-2013) and 2nd (2014-2015) years of breeding, characteristic analysis was performed through stability and uniformity tests. 'Yellow Green' has flowers that are deep-yellow (RHS#: 5A) with a red lip (RHS#: N74A) and are small in size, measuring 4.6 cm in length and 4.9 cm in width. The flowers are light-green at the beginning and gradually turn to deep-yellow. Also, the flower buds are produced easily. 'Yellow Green' flowers are a compound raceme type, suitable for pot cultivation. Its leaves grow horizontally and are about 17.5 cm in length and 6.2 cm in width. This cultivar is characterized by the absence of genetic variation, fast in vitro propagation, and vigorous growth that facilitates cultivation. This cultivar was registered (Reg.#:6268) with the Korea Seed & Variety Service (KSVS) on July 18, 2016, and the plant breeder's right is currently owned by the Kangsan Orchid Company, Korea.
