Arbuscular mycorrhizal association, its potentiality to improve wasteland inside proposed Kaziranga biosphere reserve, Assam, India

摘要

The importance of mycorrhirzae in providing nutrition to most vascular plants and maintaining the health of ecosystem has been demonstrated in last parts of the 20th century (Marks and Kozlowski, 1973; Sanders et al. 1975; andTrappe and Fogel, 1977).Further, rangeland productivity along with cropland and environmental protection correlated with different mycorrhizal aspects has been dealt by Doug et al. (2008), Boomsma and Vyn (2008), Shi et al. (2007), Turjaman et al. (2006), and Bharadwaj et al. (2007). Reddy and Goud (1989) and Reddy and Bias (1990) studied in detail the mycorrhizal correlation with the physical and biological factors. Each natural soil and weed species harbour different indigenous Arbuscular Mycorrhizal (AM) fungus population.The mycorrhizal fungus translocate colonization nutrient to the host plant. The host provides photosynthates to the mycorrhizal fungi. The mycorrhizal mycelium thus serves as highly efficient extensions of the root system. About 80 per cent of the world's plant species belong to the families that are typically mycorrhizal, the great majority of these form Vesicular Arbuscular (VA) endosymbionts.
