Description of the research topic:
Grafting has been reported to give some benefits against drought stress; however, rootstock genotype plays a key role in this tolerance. Beneficial organisms can also use to enhance plant growth and increase drought tolerance. In recent years, grafting has been found effective in overcoming abiotic stresses (i.e. salinity, drought, low temperature).
Besides the Arbuscular mycorrhizal fungi (AMF) are obligate symbionts that predominate in the roots and soils of agricultural crop plants. The interaction between the AM fungi and other soil organisms are complex; they may be inhibitory or stimulatory. The AM fungi have been shown to promote plant growth mainly by enhancing nutrient acquisition. At the present time we do not understand enough the functioning of AM fungi on grafted plants, with our research the processes can be more comprehensible.
