Abstracts |
The roots of eight plants species in six families from moderately degraded sub-tropical forest stands of Meghalaya, Northeast India were examined for arbuscular mycorrhizal fungi (AMF). All the surveyed plant species had AMF colonization in the form of arbuscules, vesicles and hyphae. The result of the investigation reveals that the percentage of AMF colonization varied in different plant species. The intensity of colonization ranges from 38.98% to 87.77%, with the lowest in Cinnamomum tamala and highest in Ophiopogon intermedius. Analysis of the rhizosphere soils showed that mycorrhizal spores were present in all locations from where the plant roots were collected. The mean spore density per 25 g of soil ranged between 38.67 and 89. Correlation analyses demonstrated that total AMF colonization shows a positive correlation (p<0.05) with spore density and also with hyphae and vesicles. The hyphal colonization had a negative correlation (p<0.05) with arbuscules and positive correlation (p<0.05) with vesicles. The present study indicated that AMF was formed in the roots of various plants in moderately degraded sub-tropical forest of Northeast India with varied rate of colonization and spore density. |
