摘要
Arbuscular mycorrhizal （AM） technology is a soil-based fertilization practice for sustainable crop productivity. We evaluated six indigenous Arbuscular mycorrhizal fungi （AMF） strains for their symbiotic response with Piper longum （long pepper）, a non-timber forest product holding promise as a commercial crop for its medicinal fruits and roots. Piper saplings were raised in a 10 cm thick sand and soil mix inoculated with various AMF. Under field conditions, plants inoculated with AMF demonstrated better survival （〉80%） than non mycorrhizal plants （58%）. Almost all the studied AMF strains increased the plant growth, biomass and nutrient content （N and P） over the uninoculated control. Mycorrhizal inoculation with four AMF species, viz： Glomus fasciculatum, G. clarum, G. etunicatum and G. versiforme greatly enhanced long pepper growth both in the nursery and field conditions.
