Arbuscular Mycorrhizal Fungi (AMF) have mutualistic relationships with more than 80% of terrestrial plant species. Arbuscular mycorrhizal fungal symbiosis have remarkable role in sustainable growth and development of plants as they help the land plants to acclimatize the biotic and abiotic conditions for their better survival, growth and development. In the present study surface sterilized tubers and seeds of potato were sown in earthen pots filled with sterile soil. Half the pots were inoculated with sterilized 30 AMF spores of the Glomus intraradices and G. mosseae and 10 g of maize root inoculated with the species of G. intraradices and G. mosseae. Another half represented controls with no AMF inoculation. Inoculation was done twice 3 days before sowing the tubers and seeds and on the onset of germination. Potted plants were regularly watered. After seedling emergence, the inoculated plants along with their controls were sampled at 20, 40, 60 and 80 days of growth. The observed data seems to predict that there is a net increase in the above and below ground growth of the plant with each 20 days interval after seedling emergence. The present study seems interesting since it pertains the work on modified stem vis a vis mycorrhizal relationship of a modified stem than normal root. The Chlorophyll content besides morphological growth parameters and fresh and dry weight content of both cultivars of potato plant are shown to present in higher level in the mycorrhiza infected as compared to the non-inoculated ones.
