Arbuscular mycorrhizal colonization of tomato by Gigaspora and Glomus species in the presence of root flavonoids
The effect of flavonoids isolated from arbuscular mycorrhizal (AM) colonized and noncolonized clover roots on the number of entry points and percentage of root colonization of tomato (Lycopersicum esculentum L.) by Gigaspora rosea, Gi margarita, Glomus mosseae and G. intrarradices symbionts was dete...
