Arbuscular Mycorrhizal Fungi Association with Some Selected Medicinal Plants
Asian Journal of Soil Science and Plant Nutrition,
Arbuscular mycorrhizal fungi (AMF) are group of fungi of the order Glomales that form symbiotic association with plant roots and enhance the uptake of nutrients, and improve plant growth and yield. This study was conducted to investigate the occurrence of arbuscular mycorrhizal fungi in the rhizospheres of some commonly grown medicinal plants in Maiduguri viz; Aloe vera, Mentha, Cymbopogon citrates and Ocimum gratissimum. The results revealed all the plants have formed mycorrhiza symbiosis. Arbuscular mycorrhizal fungi spores from five genera (Glomus, Acaulospora, Dentiscutata, Scutellispora and Gigaspora were isolated and identified. Cymbopogon citrates significantly recorded the highest total AMF spore counts (90±4.17) while Aloe vera recorded the least (54±2.28). Amongst the five mycorrhiza genus Glomus species were comparatively higher under all plant species, while, Dentiscutata and Gigaspora had the lowest spore counts. Highest percent root colonization (72±4.23%) was recorded under Cymbopogon citrates and Aloe vera recorded the least (55.5 ±2.41%). The study confirmed mycorrhiza association with all the plants, however, AMF spore counts diversity varies with plant species. Arbuscular mycorrhizal fungi could be inoculated to soils with scanty or ineffective spores for enhanced plant nutrition and growth of medicinal plants.
