Quality of floral stems of lisianthus (Eustoma grandiflorum Raf.) inoculated with Bacillus subtilis and Glomus intraradices

Abstract Lisianthus (Eustoma grandiflorum) is an ornamental species used as a potted plant or cut flower, its popularity due to the diversity of colors, number flower buds, and shelf life. Nevertheless, during first phases development, problems such foliar chlorosis root diseases affects most cultivars, causing poor growth, thin stems, few flowers. The use growth-promoting rhizobacteria (PGPR) arbuscular mycorrhizal fungi (AMF) improved growth these microbes colonize system root. Therefore, in order provide better conditions for stem aim this work was evaluate individual combined effect Bacillus subtilis Glomus intraradices on postharvest quality stems lisianthus cv. Mariachi. Then commercial product Alubión-X (Bacillus fungus (Glomus intraradices) were used. variables evaluated height diameter, area, leaves postharvest, buds number, open diameter flowers dry weight. results showed significant inoculation G. size (66.92 cm) stem, well combination B. + (65.51 compared control (36.9 cm). treated with 33.35 23.9 respectively significantly higher than control. alone best option applying lisianthus, when Subtilis.
