Pelargonium graveolens, rose-scented geranium, is commonly used in the perfume industry. P. graveolens enriched with essential oils, phenolics, flavonoids, which account for its tremendous biological activities. Laser light treatment and arbuscular mycorrhizal fungi (AMF) inoculation can further enhance phytochemical content a significant manner. In this study, we aimed to explore synergistic impact of these two factors on graveolens. For this, four groups surface-sterilized seeds: (1)...
