Response of Arbuscular Mycorrhizal Fungi on Growth and Chlorophyll Content of Three Varieties of Gossypium herbaceum L

摘要

Cotton (Gossypium herbaceum L.) is an important cash crop of Gujarat and Maharashtra in India. Soil microflora play a significant role in plant growth. A large number of hybrid and Bt cotto varieties are introduced in the field. Considering the fact that not much data is available on effect of AM fungi on growth performance of cotton varieties, the present study was planned to investigate the effect of arbuscular mycorrhizal fungi on growth and chlorophyll content three different varieties of cotton. A significant increase in all the varieties (Non Bt, Ajeet-11 and Vikram-5) over control in root and shoot length and their dry weight, was recorded. Changes in chlorophyll contents of a, b and total chlorophyll were also observed. It is clear from the observation that the inoculation of cotton plants with AM fungi was helpful in enhancing the plant growth.
