Endomycorrhiza also known as a Arbusculer mycorrhiza since it forms arbuscules into the plant root cells.
It increased overall absorption capacity of plant root cells through morphological & physiological changes. It helps in better utilization of low-available nutrients & retention of soluble nutrients , thus reducing reaction with soil colloids.
It also increased mobilization & transfer of macronutrients (P,N,K) & micronutrients(Cu,Zn).
It increased establishment , nodulation & atmospheric N2 fixation capacity in legumes plants.
It modify the pathogen-plant interaction thus reducing susceptibility to soil born diseases. AM fungi detoxify the environment for plant growth.
