Root Growth and Yield of Rice Plant Associated with Arbuscular Mycorrhizal Symbiosis under Salt Stress

The presence of excessive salt around root system disrupts water and nutrient uptake by root, causes inhibition of plant growth resulting in low plant yield. Arbuscular mycorrhizal (AM) symbiosis known for its mutualism towards plant by enhancing plant root growth. This study examined how AM symbios...
