Abstract
The influence of root exudates on colonization of arbuscular mycorrhizal (AM) fungi was evaluated. Root exudates of cucumber (Cucumis sativus ) and carrot (Daucus carota ) were supplied to each of the seedlings grown in soil containing AM fungi. AM colonization was significantly suppressed in C. sativus treated with root exudates from D. carota as well as in D. carota treated with root exudates from C. sativus . Detection (%) of AM fungi belonging to Glomus and Acaulospora and/or Entrophospora was remarkably reduced in C. sativus and D. carota treated with root exudates from D. carota and C. sativus , respectively.
