Propagação por sementes de Schlumbergera truncata (Haw.) Moran (flor-de-maio) em diferentes substratos

Abstract

Schlumbergera truncata (Haw.) Moran (Cactaceae), known as “flor-de-maio”, is a Brazilian endogenous herbaceous epiphytic species, much appreciated as ornamental for the beauty of its flowers. This species is multiplied by seeds, but commercially it is propagated by cuttings and grafting. The aim of this research was to evaluate the germination of four varieties of colors of this species (pink, red, white and yellow) in five substrates (vermiculite, de-fibered tree ferns, sand, commercial substrate Rendmax® Floreiras and a mixture of 50% of the commercial substrate Rendmax® Floreiras + 50% tree ferns). The results showed that this species can be easily reproduced by seeds. The commercial substrate Rendmax® Floreiras provided the best germination result.
