UEL 6: nova cultivar de Dendrobium

Abstract

médio de flores por pseudobulbo é de 15, tendo sido observadas até 31 flores por pseudobulbo. UEL 6 apresenta flores com duração média de 20 dias, perío-do superior ao Dendrobium nobile selvagem, conhecido como "olho-de-boneca", cujas flores têm duração de onze dias. MANUTENÇÃO E DISTRI-BUIÇÃO DE PLANTASPlantas da cultivar UEL 6 são mantidas pelo Depto. de Agronomia da UEL. REFERÊNCIAS

Morphological effects of induced polyploidy in Dendrobium nobile Lindl. (Orchidaceae)

“…The diploid and tetraploid plants had flowers with an average duration of 11 days, which was the same duration of wild D. nobile flowers (Faria et al 2009). In this study, the tetraploid plants had greater flower heights (4.54%) and lip widths (18.46%) when compared to diploid flowers ( Figure 1 and Table 1).…”

“…The increased number of internodes (region between two nodes) proved to be a morphological variable that is economically viable because the orchid has lateral inflorescence starting on pseudobulb nodes forming several groups with two or three flowers each (Faria et al 2009). …”

“…The value of D. nobile depends on the sales of specific visual patterns transferred by genetic inheritance, such as color, size and shape of the flower. Breeding programs for Dendrobium aim at obtaining plants for the market with desirable characteristics, for example, pseudobulbs with high vigor, upright flowers, a large number of flowers and variability of colors and shapes as well as an extended flowering season (Faria et al 2009). In Brazil, however, there have been few studies on breeding orchids due to the long cycle of plants in the Dendrobium genus, which leads to an average flowering development of three to four years.…”

Cattleya forbesii x Cattleya bowringiana: a new hybrid of Cattleya orchid

“…Faria et al (2009), Faria et al (2011), and Faria et al (2013, working with Dendrobium crosses, were successful in obtaining three new cultivars (UEL 6, UEL 7 and UEL 8), which expressed the desired characteristics of mother plants such as flower size, flower coloration, flourishing period, number of flowers, plant height, among others. also obtained a hybrid of Oncidiuns which, besides presenting desirable agronomic characteristics for a hybrid, gave more balance and symmetry to the flowers, between the floral whorls.…”
