10.22376/ijpbs.2019.10.1.p1-12 Volume 12 Issue 3 2021 (July-September) Physiological performance of plants in general, particularly cultured plant productivity and crop quality depend on the rhizosphere characteristic feature, an area of great interest to plants, producers, consumers and environmental health. Among the rhizosphere components, arbuscular mycorrhizal fungi (AMF) are one of the most common types of symbiotic association between some rhizospheric microorganisms and plant roots. AMF leads to the production of reactive oxygen species (ROS) which stimulates formation of highly active signaling compounds capable of triggering production of bioactive compounds (secondary metabolites) that enhances the medicinal value of the plant.The study revealed that inoculation of AMF cause significant increase in length of root and shoot, plant height, fresh and dry weight, relative water content, membrane stability index and total chlorophyll. Changes in total carbohydrate, total free amino acid, total protein content, carotenoids, tocopherol and flavonoids content were also observed. Constitutive activities of CAT, POD, DPPH and ABTS showed an enhancement due to AMF inoculation studied. AMF concomitantly increase essential oil production and biomass in an herbaceous species rich in commercially valued essential oils. Therefore, AMF potentially represent an alternative way of promoting growth of important medicinal herb, as natural ways of growing such crops are currently highly sought after in the herbal industry.
