Propagation of Dyckia vicentensis, an endemic bromeliad of the Pampa biome, Brazil
Abstract Dyckia vicentensis is an endemic species of the southwestern region of Rio Grande do Sul (RS, Brazil), which presents high ornamental and economic value. Thus, the aim of this study was to test in vitro and ex vitro conditions for its propagation. For in vitro germination, disinfested seeds...
