Gontijo,Júlia Brandão; Andrade,Gracielle Vidal Silva; Baldotto,Marihus Altoé; Baldotto,Lílian Estrela Borges.
ABSTRACT: Inoculants containing bacteria which promote growth in plants can increase productivity and both the economic and the environmental cost in plant crop systems. Similarly, in the flower and ornamental plant sector, the use of diazotrophic bacteria is a promising approach for improving orchid propagation from tissue culture to the ex vitro environment. We isolated diazotrophic bacteria from the roots and leaves of Cymbidium sp. The isolates were used to inoculate Cymbidium sp. plantlets during acclimatization in the nursery. After 150 days, plants were collected and their morphological and nutritional characteristics assessed. Eight bacterial strains were isolated containing traits that promote plant growth: Bacillus thuringiensis, Burkholderia...
