摘要

This research was conducted to verify the in vivo effects of light-emitting diodes (LED) on propagule formation of arbuscular mycorrhizal fungi (AMF) in pots cultivated with bahiagrass and millet. A glass pot was separated into two sections, inside and outside, and placed in a paper box covered with aluminum foil. In the inner section, spores of AMF, bahiagrass, and millet seedlings were inserted, while the outer section was filled with glass beads (1 mm diameter). Spores of the AMF, Gigaspora margarita Becker and Hall, from commercial inoculums and two kinds of LED, red and blue, were utilized for this experiment with different combinations: dark (the control pot), blue, red, red+blue, red/blue (alternated every 12 h) and red-blue (red for 60 days followed by blue for 30 days). The experiment was conducted for a total of 90 days. Among LED treatments the red-blue induced higher plant growth in millet seedlings although the growth did not surpass the one of the control. This response was less notorious in bahiagrass. On the other hand, the plant growth under blue LED was always lower than the control. The red-blue and red alone treatments stimulated the formation of AMF spores in glass beads, whereas the blue treatment alone inhibited it. In summary, based on AMF colonization and sporulation, red-blue and red alone treatments were the most efficient.
