STUDIES ON THE ARBUSCULAR MYCORRHIZAL FUNGAL DIVERSITY OF SELECTED MEDICINAL PLANT SPECIES FROM KODIKUTHIMALA, MALAPPURAM, KERALA

The present investigation has brought out the AM fungal association in some plant species of Kodikuthimala, Malappuram district Kerala. Totally, 25 plant species belongs to 15 families were analyzed for arbuscular mycorrhizal association. The root samples of all collected plant species showed mycorrhizal infection. The percentage of colonization was varied with plant species and it ranges from 12 (Commelina benghalensis) to 79% (Sida rhombifolia). Maximum spore population was observed in Gloriosa superba (574/100g of soil) and minimum in Euphorbia hirta (143/10g of soil). Totally 26 AM fungal species belongs to 13 genera were found. Among this Glomus was most dominated. In most of the plants, spores of Rhizophagus fasciculatus are seen. Present study confirms the Arbuscular Mycorrhizal association in the collected plant species.

Arbuscular Mycorrhizal Fungal

Arbuscular mycorrhizal fungal communities in northern temperate ecosystems must function during extremes in environmental conditions. However, it is not known if arbuscular mycorrhizal fungi that co-exist in soil communities have similar tolerances to stresses such as drought and freezing. The phenology of arbuscular mycorrhizal fungi was determined over one year in a community in southern Ontario, Canada. Five fungal species from the same community were then used to inoculate five plant species, in all possible combinations, and were subjected to either a freezing treatment or a drought treatment after which new seedlings were transplanted into the treated pots. The percent colonization of roots of each plant species was measured as the difference in mean colonization from the control. Freezing reduced percent colonization in almost every case, whereas drought resulted in both increased and decreased percent colonization. Fungal species responded differently to the treatments, and there was a pronounced plant × fungus effect. These results support the hypothesis that distinct functional groups of arbuscular mycorrhizal fungi exist, and these may determine plant community structure.Key words: arbuscular mycorrhizal fungi, freezing, drying, functional diversity.
