INTRODUCTION. The fungus root symbiotic relationship is called mycorrhizae.. All mycorrhizas have intimate contact between hyphae and plant cells in an interface where nutrient exchange occurs. All potential host fungus pairs should ideally be tested for all the following characteristics. Rapidity and extent of mycorrhization. Host response. Efficiency of inorganic nutrient uptake. Water relation.
