Tolerance of lonkida (Nauclea orientalis L.) seedlings inoculated with mycorrhizae against drought and waterlogging stress

Abiotic stress is a limiting factor for plant growth and development. The use of arbuscular mycorrhizal fungi can reduce the negative effects abiotic stress. This study aimed to determine tolerance <em>Nauclea orientalis</em> inoculated with mycorrhizae drought waterlogging stresses. research was carried out at Indonesian Mycorrhizal Association’s greenhouse Forestry laboratory University Halu Oleo in Kendari City, Southeast Sulawesi Province, Indonesia, from March June 2019. used factorial completely randomized design consisting two factors. first Arbuscular Fungi (AMF) inoculations (A) control, AMF types <em>Acaulospora</em> <em>sp.-1</em>, <em>Claroideoglomus etunicatum. </em> secod environmental treatments (B) soil moisture 25% field capacity, 50% inundated as high polybag (9 cm high) over polybag. results showed that local effective improving growth. Interaction between inoculation sp.-1 significantly increased colonization on <em>N. roots. Inoculation <em>C.etunicatum</em> improved treatment capacity negatively influenced dry weight relative orientalis</em>.
