Abstract

Five forest species viz. Bamboo, Teak, Eucalyptus, Acacia and Neem were investigated for arbuscular mycorrhizal association and its morphological characteristics isolated AM spore from three different locations viz. Nagpur, Ramtek and Umred region. AM spore isolated by using wet-sieving and decanting method. Only one type of AM spore i.e. Glomus was associated with all the forest species of three different locations of Nagpur. The shape of Glomus sp. was Globose to sub-globose elongated, irregular sometime and colour of Glomus sp. was light yellow to bright orange and brown black to dark black at maturity observed. Bamboo showed maximum number of spores in the rhizosphere at three different locations viz. Nagpur, Ramtek and Umred i.e., 18, 20, 23 per 100g soil respectively and maximum per cent root colonization and Neem showed minimum number of spores in the rhizosphere i.e., 8, 5, 7 per 100g soil of Nagpur, Ramtek and Umred, respectively and minimum per cent root colonization.

Conclusion

Mycorrhiza play crucial role in native ecosystems such as forest where fertigation of extensive land area with large quantities of phosphorous is not practical (Habte, 2000). Mycorrhiza provide wide range of services viz. nutrient uptake, leaching, contribution to soil structure and mycorrhizal fungal networks acting as hyphal highways for bacterial dispersion (Marcel et al., 2009) also, mycorrhiza able to retard pathogen development in root system due to high chitinolytic activities (Dehne,1982). Mycorrhiza play crucial role in natural forest ecosystem and also in agriculture system. The status of mycorrhizal colonization in forest species of Nagpur region had not been studied so far and hence there is urgent need to know the different mycorrhizal species associated with forest species of Nagpur region and their role for disease management in agriculture ecosystem.
