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

Arbuscular mycorrhizal (AM) fungi are well known symbiotic microorganism found to improve the growth of host plant by mobilizing immobile nutrients, mainly phosphorus, from the soil. However, the effect of AM fungi on host plant growth depends on the percentage mycorrhizal colonization, whereas it is not clear that the percent mycorrhization impacts by AM fungal spore abundance of the inoculum. Therefore, the current investigation was conducted to know the effect of percent mycorrhization of Glomus intraradices on the growth of blackgram inoculated with varied numbers of AM fungal spores via seed biotization (1 to 10 AM fungal spores per seed). Percent mycorrhizal colonization and plant growth characteristics of blackgram were recorded after 10, 20 and 30 days of sowing (DOS). Our results are revealed that the percentage of mycorrhizal colonization significantly influenced based on the availability of AM fungal spore richness of the biotized seeds, which leads to altered crop growth...
