Abstract

Among commercial plants utilized in floriculture in Mexico State, Lilium species have a great production volume, with problems associated with high use of chemical fertilizers, soil salinity and water pollution. Sustainable strategies are required to minimize impacts on the ecosystem without diminishing quality products. Main effects and the interactions of phosphorous, Glomus fasciculatum and Bacillus subtilis were evaluated under greenhouse conditions. Twelve treatments arranged in a 2x3x2 factorial with 10 replications by treatment were studied. Results showed that G. fasciculatum combined with 22 μg/ml P and B. subtilis had a positive correlation with root colonization, root dry weight, stem diameter, shoot dry weight, flowering period, flower diameter, petal width, flower dry weight, flower lifespan, net photosynthetic rate and tissue contents of Zn, Cu and Fe. Results indicate that study rhizospheric microorganisms can positively interact to promote growth and development of Lilium plants, thus improving commercial flower quality, saving chemical fertilizers and protecting soil resources.
