| We tested the effects of the flavonoid 3-methoxi-5,6,7,8-hydroxy-4'hydroxy flavone (NMHTV) isolated from shoots of non arbuscular mycorrhizal (AM) inoculated clover, and of the flavonoids 5,6,7,8-hydroxy-3-methoxy flavone (MH-1); 5,6,7,8-hydroxy-4'-hydroxy flavone (MH-2); and 5,7-hydroxy-3,4'-methoxy flavone (MH-3); isolated from AM clover {Trifolium repens) shoots, on spore germination, hyphal length, hyphal branches and the number of cluster of auxiliary cells or the number of secondary spores (Presymbiotic stage) and on the number of entry points and the percentage of AM colonized root of tomato (Lycopersicum esculentum) by the AM fungi Gigaspora rosea, Giaspora margarita, Glomus mosseae and Glomus intraradices (Symbiotic stage). Non significant effects... |

| Mycorrhizal associations in Smallanthus sonchifolius (Poepp. & Endl.) H. Robinson (Asteraceae), Yacon, an ancient Andean crop and Smallanthus macroscyphus (Baker ex Martius) A. Grau, wild yacon, a close wild relative are described for the frst time. Yacon fbrous roots growing under feld conditions have high levels of colonization by arbuscular mycorrhizal fungi (86 %). Other fungi colonizing roots included dark septate endophytes (45 %) and unidentifed fungi that are probably saprophytic (25 %) were observed. Only 9% of the samples analyzed were not colonized by any type of fungi. Glomus, Acaulospora, Scutellospora, Gigaspora and Pacispora were the main genera of arbuscular mycorrhiza identifed. A similar high degree of mycorrhizal colonization was... |
