“…Effect of CW was tested at 0, 5, 10, 15 and 20 % 12-h PP, 1000 lux, 23 ± 2°C 20 % CW was optimal for longest and most pseudobulbs, most and longest leaves and roots, and highest plant fresh weight Soares et al (2013) D. wangliangii The authors referred to the structures as PLBs, but in fact they were protocorms Plant Cell Rep for Dendrobium, mainly because each mature capsule contains 2-3 million seeds with a high percentage of viable seeds that can germinate under in vitro asymbiotic conditions (Paul et al 2012). Another commercially important application of asymbiotic germination is in breeding programmes aimed at accelerating the speed at which new cultivars are obtained (Cardoso 2012). This review aims to examine the available literature (53 studies; Table 1) related to asymbiotic in vitro Dendrobium seed germination (covering 37 species and multiple hybrids; Table 2) in a bid to identify those trends that could assist researchers better formulate a study or conservation programme for commercial or for rare species and hybrids.…”

“…Lone et al (2008) also observed a variation of 4.23-6.89 cm in plant height, 5.2-12.87 roots/plantlet, and 0.23-0.63 g of total fresh weight/plantlet after 109 crosses using D. phalaenopsis. Seed propagation is commonly used for conservation of endangered species, and for breeding purposes (Faria et al 2004b;Lone et al 2008;Cardoso 2012). In these cases, genetic variation is a positive factor expected for conservation or development of new cultivars.…”

The ability to germinate orchids from seeds in vitro presents a useful and viable method for the propagation of valuable germplasm, maintaining the genetic heterogeneity inherent in seeds. Given the ornamental and medicinal importance of many species within the genus Dendrobium, this review explores in vitro techniques for their asymbiotic seed germination. The influence of abiotic factors (such as temperature and light), methods of sterilization, composition of basal media, and supplementation with organic additives and plant growth regulators are discussed in context to achieve successful seed germination, protocorm formation, and further seedling growth and development. This review provides both a basis for the selection of optimal conditions, and a platform for the discovery of better ones, that would allow the development of new protocols and the exploration of new hypotheses for germination and conservation of Dendrobium seeds and seedlings.

“…To have an idea of the importance of this genus in the expansion of world floriculture, only in the Dutch market, the largest in the world, in 2014, 121 million pots of Phalaenopsis were sold generating approximately US$ 500 million [6]. In addition to Phalaenopsis, other genera of economic importance to floriculture include the genera Cattleya, Dendrobium, and Oncidium and their hybrids [7][8][9] as well as Cymbidium and Vanda used for production of potted or even cut flowers.…”

The process through induction, proliferation and regeneration of protocorm-like bodies (PLBs) is one of the most advantageous methods for mass propagation of orchids which applied to the world floricultural market. In addition, this method has been used as a tool to identify genes of interest associated with the production of PLBs, and also in breeding techniques that use biotechnology to produce new cultivars, such as to obtain transgenic plants. Most of the molecular studies developed have used model plants as species of Phalaenopsis, and interestingly, despite similarities to somatic embryogenesis, some molecular differences do not yet allow to characterize that PLB induction is in fact a type of somatic embryogenesis. Despite the importance of species for conservation and collection purposes, the flower market is supported by hybrid cultivars, usually polyploid, which makes more detailed molecular evaluations difficult. Studies on the effect of plant growth regulators on induction, proliferation, and regeneration of PLBs are the most numerous. However, studies of other factors and new technologies affecting PLB production such as the use of temporary immersion bioreactors and the use of lighting-emitting diodes have emerged as new tools for advancing the technique with increasing PLB production efficiency. In addition, recent studies on Phalaenopsis equestris genome sequencing have enabled more detailed molecular studies and the molecular characterization of plantlets obtained from this technique currently allow the technique to be evaluated in a more comprehensive way regarding its real applications and main limitations aiming at mass propagation, such as somaclonal variation.

“…However, commercial blooming in this hybrid, with higher number of flowers and longer inflorescences were obtained in the second blooming (plants with approximately 1.5 to 2 years after acclimatization), compared with the first ones. This characteristic of rapid flowering has importance for commercial production of orchids because allow the production of flowers in competitive period compared with other commercial genera as Dendrobium and Phalaenopsis orchids (CARDOSO, 2012;CARDOSO et al, 2016).…”

Orchids are considered one of the most important potted-flowering in the world. Oncidium genus, as well their hybrids group (OHGs) has used for the flower market as pot or cut flower. However, some horticultural characteristics require improvements, e.g. the production of precocious cultivars, independent-season blooming or easy flowering induction, high quality and durability of flowers and variations in color of flowers, to compete with Phalaenopsis and Dendrobium orchids, as other flower groups. Aiming this purpose there were used hand-crossing pollination between the Oncidium 'Sweet Sugar' and Ionopsis utricularioides, a Brazilian wild species, for evaluate the capacity of crossing and to select progenies with interest of use in floriculture as new cultivar. The seeds obtained from this cross were seeded on in vitro conditions, followed by acclimatization and cultivation on greenhouse conditions until de flowering time. One of the plants obtained presented interesting characteristics, as good and rapid vegetative development and high quality of blooming. This hybrid obtained from an intergeneric crossing resulted in a plant with vegetative and flower type characteristics and color similar of Oncidium female parent, but with larger number of ramifications in inflorescence and number of flowers (60% and 219,4%, respectively) than Oncidium parent (♀), and with more similarity with Ionopsis (♂). This hybrid cultivar, called Ionocidium 'Cerrado 101' is one more option of OHGs in this competitive market and can be used either for pot and also for cut orchid flowers production, main because it longer inflorescence (83 cm). Keywords: Oncidium, Ionopsis utricularioides, breeding, progenies selection, new hybrid. RESUMOIonocidium 'Cerrado 101': hibrido intergenérico de orquídea com alta qualidade de floração. As orquídeas estão entre as mais importantes flores de vaso do mundo. O gênero Oncidium, assim como seus híbridos (OHGs), são plantas com grande potencial para o mercado de flores de corte ou vasos. Entretanto, esse grupo ainda requer a melhoria de algumas características horticulturais, como florescimento precoce, produção de inflorescências independente das estações do ano ou com facilidade na indução e controle do florescimento, além de alta qualidade e durabilidade das flores e produção de cultivares com colorações diferentes daquelas existentes. Essas condições são necessárias para que os Oncidium possam competir no mercado com orquídeas de outro gênero como Phalaenopsis e Dendrobium, bem como outras espécies de vaso e corte. Para tanto, foram realizados cruzamentos entre Oncidium 'Sweet Sugar' e uma espécie nativa do Brasil, Ionopsis utricularioides com o objetivo de determinar a capacidade de cruzamento por polinização manual controlada, e selecionar progênies de interesse para propagação clonal e uso na floricultura como nova cultivar. As sementes obtidas do cruzamento foram colocadas para germinação e desenvolvimento das plântulas in vitro, seguido do cultivo em casa de vegetação até o momento do...
