Resumen
Inglés Español
Plants are colonized by an array of microorganisms that have deletereus, neutral or beneficial effects on growth of the host plant. In order to obtain preliminary information about the leaf-associated bacteria of the orchid Lycaste aromatica, leaves exhibing foliar necrotic spots from ten plants were collected in Comitan, Chiapas; Cuetzalan, Puebla, and Cordoba, Veracruz, Mexico. Forty two isolates were obtained; their genera and proportion were as follows: Bacillus, 38% (Cuetzalan 9%, and Cordoba 29%); Enterobacteriaceae, 36% (Comitan 10%, Cordoba 24%, and Cuetzalan 7%); Pseudomonas, 7% (Comitan 5%, and Cordoba 2%); Xanthomonas, 5% (Cordoba); Clostridium, 2% (Cordoba), and bacteria with coccus morphology, 12% (Cuetzalan 5%, and Cordoba 7%). None of the isolates were pathogenic and based on the total indol production test, none were plant growth promoters through auxin production; however, Bacillus, Enterobacteriaceae, and Pseudomonas are known for their antagonistic capacities against other microorganisms.
