Abstract
The objective of the study was to find out biodiversity of AM fungi associated with selected medicinal plants in Maharashtra Nature Park, which was a dumping ground of Mumbai city almost four decades ago. The ten plants selected for the study were Bombax ceiba, Bauhinia variegata, Madhuca longifolia, Piper longum, Asparagus racemosus, Ocimum sanctum, Plectranthus amboinicus, Bryophyllum pinnatum, Costus igneus and Justicia adhatoda. Root zone soil and roots were collected from a depth of 20cm during the period between March 2019 and June 2019. The soil and roots were screened for Arbuscular Mycorrhizal (AM) spore count and root colonization. Highest spore density was found in Madhuca indica (296 spores/20 g of soil), while minimum spore density was found in Asparagus racemosus (42 spores/20 g of soil). The dominant AM genera found were Acaulospora and Glomus. Gigaspora was found in two plants. Isolation Frequency of Acaulospora was 90% and that of Glomus was 70%. Spore density found was highly variable in the ten plants. Maximum root colonization (100%) was found in Bryophyllum pinnatum while minimum root colonization of 30% was found in Piper longum. Root colonization in the roots was in the form of arbuscules, vesicles, spores (intra radical and extra radical spores), hyphae and sporocarps. Another type of potentially beneficial fungi, namely dark septate endophytic fungi (DSEF) was observed associated with the roots of Asparagus racemosus.
