A. MAHMOOD, RUBINA IQBAL, RAIHA QADRI AND SAEEDA NAZ

Abstract: In young roots of Leucaena leucocephala infection hyphae formed appresorium, sending branches in different directions to colonize the host cell. The mycorrhizal fungus was non-septate and branched. Fungal cells (Pelotons) were observed in the root cortex. Characteristic arbuscules commonly formed by VAM fungus were visible. The main hyphae branched and the branched hyphae terminated in an arbuscule. The cortical cells of the root showed large number of vesicles which were either globular or elliptical in shape.
