Effect of Glomus intraradices spore abundance of the inoculum on percent mycorrhizal colonization and growth of Vigna mungo (L.) Hepper

Arbuscular mycorrhizal (AM) fungi are well known symbiotic microorganism found to improve the growth of host plant by mobilizing immobile nutrients, mainly phosphorus, from soil. However, effect AM on depends percentage colonization, whereas it is not clear that percent mycorrhization impacts fungal spore abundance inoculum. Therefore, current investigation was conducted know Glomus intraradices blackgram inoculated with varied numbers spores via seed biotization (1 10 per seed). Percent colonization and characteristics were recorded after 10, 20 30 days sowing (DOS). Our results revealed significantly influenced based availability richness biotized seeds, which leads altered crop growth. in roots increased increasing ranges 70 %. Moreover, colonized plants higher shoot root length, leaf area, area index, biomass production as chlorophyll content over control, conversely further directly proportional seed. one governing factors influence besides species soil condition.
