RUBI ARRIAGA, M et al. Interrelationship between phosphorus, Bacillus subtilis and Glomus fasciculatum with Lilium quality. Phyton (B. Aires) [online]. 2012, vol.81, n.1, pp.59-68. ISSN 1851-5657.
Lilium is an ornamental species which production and commercialization have a greater daily economical importance because of its acceptance by the market. Crop of Lilium is currently under an intensive production system based upon an indiscriminate use of chemical fertilizers, without precise plant nutrition recommendations. Because of this, producers are forced to set up sustainable production processes without affecting the quality of the product, since worldwide consumers prefer products that have been correctly harvested. Objectives of this study were to assess the main effects and the interactions of phosphorus applications and the inoculation with Glomus fasciculatum and Bacilllus subtilis, on the commercial flower quality of Lilium oriental hybrid Showwinner. In 2008, 12 treatments were assessed in a greenhouse under a factorial arrangement 2×3×2, that corresponded to the treatments: inoculated and non-inoculated and 0, 22 and 44 µg/mL of phosphorus. The treatment that combined G. fasciculatum with 22 µg/mL of phosphorus and B. subtilis showed a positive correlation with root dry weight, plant height, stem diameter, stem dry weight, petal wide, flower diameter, flower dry weight, flower color and briskness, flowering period, photosynthetic rate and stem zinc (Zn), nitrogen (N), phosphorus (P), copper (Cu) and potassium (K) concentrations. Inoculation with the study rhizosphere microorganisms plus using an intermediate phosphorus concentration interacted positively to improve Lilium flower quality.
