  In the present study, we screened endophytic fungi in roots of mature plants of the epiphytic orchid Cattleya skinneri to test their potential to improve seed germination in C. skinneri and growth and development in acclimatizing plantlets of C. aurantiaca and Brassavola nodosa. We isolated 108 fungal colonies belonging to 11 genera and statistical differences were not found between samples according to season or orchid substrate. Germination experiments were carried out using three methods and eight strains that proved to be manageable under laboratory conditions. None of these strains proved to be promoters of seed germination in C. skinneri. For ex vitro plants of C. aurantiaca, three strains (Trichoderma IBTZ-0200F, Epulorhiza IBTS-0200G and Botrytis IBTZ-0200A) showed mycorrhizal characteristics, whereas none of the evaluated strains promoted plant growth in B. nodosa. Fungal strain specificity and their function as mutualists, neutral or latent pathogens are discussed in the light of the results obtained.

  In Central America, native bromeliads are an alternative for productive diversification in coffee plantations; however, first, a census in each area should be carried out and inventories must be up-dated. During 2004 and 2005, field explorations were carried out in the Soconusco region, on the Mexico/Guatemala border, in order to collect live specimens and to create a reference collection of plants in the University (UNACH, Universidad Autónoma de Chiapas, Tapachula). To verify if the collected species were native or not, an ethnobotanical study was carried out, with semi-structured interviews applied to people from the visited communities; the information was then compared with the literature. The study revealed few uses of native bromeliads. To date, we have 186 accessions which had been characterized and classified in 6 genera and 29 species. This number of species comprises only 22.8% of the bromeliads of Chiapas, but represents a high density of species (3.113 species/1000 km2). Most of the accessions are from middle altitudes (500-1500 m.a.s.L.). We present the first inventory of the flora Bromeliaceae for the region of Soconusco.
