Potencial ornamental de Schomburgkia crispa Lindl

Abstract

Orchids are one of the plants groups with greater potential of commercialization, since they present the best characteristics of the forests more valued in the sector of the flowers and ornamental plants. However, as the most commercialized species are exotic, and the native ones are still little explored as to their ornamental potential. Thus, the aim of this work is describing the aspects of the morphology of Schomburgkia crispa Lindl., in order to evaluate its ornamental potential. The study was carried out in twelve - year old plants, from the State Park of the Várzeas do Rio Ivinhema - MS. The plants were allocated in a screened greenhouse (PAR = 235.1 μmol m-2 s-1) located in the Orquidário of the Faculty of Agricultural Sciences - FCA / UFGD. For the evaluation of the ornamental potential of the species, six individuals were chosen, of which the quantitative traits were evaluated in all plants, totaling fifty pseudobulbs and eightyeight flowers. During flowering a more representative plant was chosen for the visual evaluation of the plant's morphological aspects by means of photographs. To portray the morphology of flowers was an elaborate floral diagnosis plug, from photos of fresh flowers, keeping the maximum of morphological details. At the end of the trial period were calculated the average and standard deviation for each of the traits. The S. crispa had on average plants with 46.17 cm in length, 31.50 cm in width and 88 cm in diameter. As for the characters of flowering species, generally presented flowers per plant 16.50, and 14.67 and 4.66 per flower stem flowers open daily, with average duration of 32 days. Thus, it was possible to conclude that S. crispa presents high ornamental potential for use in ornamental horticulture.
