| Sumario: | The flower market is characterized by being
both eager for novelties and highly competitive.
The exploration of native species with ornamental
potential represents a remarkable area of research,
since it entails the introduction and development
of novel promising ornamental crops. The genus
Glandularia, widely distributed in Argentina, holds
an enormous ornamental potential, due to the
variety of colors of its inflorescences (red, violet,
white, rose and lily), and extended flowering
period. There is little information on tissue culture
of Glandularia, thus highlighting the relevance of
this research. In this work, the conditions for in vitro
multiplication of G. peruviana were optimized. It
was concluded that WPM supplemented with TDZ,
in concentrations ranging from 1.1 to 9.0 μM,
was the most adequate treatment, rendering a
multiplication rate of approximately 10 de novo
shoots per explant. This paper presents a protocol
for the in vitro propagation of this species and
introduces interesting prospects in the application
of biotechnological tools to breed Glandularia.
