Effects of fluoride toxicity on Glomus fungi spore count and their root colonisation in Ocimum basilicum

Author(s): Nidhi Yadav
Abstract: The aim of present study was to assess the effects of different Glomus fungi on the growth of Ocimum basilicum (Medicinal and Aromatic plant) grown under salinity stress. The fluoride concentration was kept similar for all treatments while different arbuscular mycorrhiza fungi were used. Most fluoride tolerant variety of fungi found was Glomus mossae. G. mossae showed best stress tolerant results followed by Glomus fasciculatum, Glomus intraradices and Glomus aggregatum. 50ppm of NaF was used as the treatment given to plants. After 3 months, it was found that the plants in salinity stressed soils when treated with Glomus mossae fungi resulted in 15% decrease in spore count and 19% decrease in root colonisation in plants. In sodium fluoride treated plants, Glomus mossae showed better stress coping effect in comparison to other Glomus fungi resulting better plant productivity even in stressed conditions.
