The purpose of this book is to explain and summarize the beneficial role of AM fungi during normal and abiotic stresses. Now days due to increasing use of chemical fertilizer the soil became saline and barren. Another major problem is low rainfall which increasing drought prone areas. These two things directly affecting yield as well as human health. To overcome these problem microbial inoculants such as Arbuscular mycorrhizal fungi is the best solution. Role of AM fungi during abiotic stress and growth in Allium sativum. Book covering number of aspect like isolation and culturing of AM fungal species for inoculation to garlic plants, presymbiotic response during AM inoculation, beneficial role in growth, antioxidant defence response during abiotic stress and beneficial role in increasing yield. Role of AM fungi during abiotic stress and growth in Allium sativum is the only book available to inoculate and see the beneficial role of AM fungi during drought, salinity and under field conditions. It is essential reading for researchers to take methodology for using AM fungi under field conditions and also reclamation of saline and drought prone areas.
