ARBUSCULAR MYCORRHIZAL FUNGAL DIVERSITY AND ROOT COLONIZATION OF SOME MEDICINAL PLANTS RHIZOSPHERE SOIL OF VRIDDHACHALAM, TAMIL NADU.
Journal Title: International Journal of Pharmacognosy - Year 2015, Vol 2, Issue 1
Abstract
The present study was to analyze the occurrence of mycorrhizal diversity in 20 medicinal plants of Vriddhachalam, Cuddalore District, Tamil Nadu and to explore for structures correlated to the possible functional position of the symbiosis. Arbuscular mycorrhizal fungal colonization ranged from 24-81%. The highest infection was found in Justicia gendarussa and lowest in Naregamia alata. AM fungal spore population with a range of 140 to 620 in100 g of rhizosphere soils was detected. The maximum spore population was observed in the species, Maranta arundinaceae (620/100g of soil) and the minimum in Achyranthes aspera (140/100g of soil). The AMfungal species were isolated which belongs to four genera (Aculospora, Gigaspora, Glomus and Scutellospora) and among them, Glomus was dominant genera. The soil pH was also determined.
