GARCIA-ALBARADO, J. Cruz et al. Wild herbaceous species propagation with potential for landscaping. Rev. Mex. Cienc. Agríc [online]. 2013, vol.4, n.spe5, pp.1043-1047. ISSN 2007-0934.

In this research we evaluated the sexual (by seed) and asexual propagation (by cuttings) of Ruellia nudiflora, Centratherum punctatum and Salvia coccinea, in different combinations of substrates based on vermicompost, peat, sand and vermiculite. Vermicompost and peat volumes ranged from 50 to 100% (v/v), while the sand and vermiculite did it from 0 to 50% (v/v). With respect to the seeds, the species that responded more efficiently to the treatments was S. coccinea, achieving up to 90% germination on substrates containing 100% vermicompost or peat, while R. nudiflora only reached 6% germination rate using 60% peat in the substrate, and C. punctatum achieved 36.6% germination in substrates with 50% vermicompost. Regarding the cuttings, C. punctatum achieved 60% of surviving in the mixture containing 80% peat, and S. coccinea only achieved 40% with 100% of peat as substrate, while R. nudiflora had no response to this treatment at all. We concluded that under the experimental conditions tested, these three species are able to spread, which is the first step in establishing protocols for their use for landscaping.
