Outline of Final Research Achievements

Mycorrhizal fungi can play important in regulation of plant metabolism, but less is known about how the differences of mycorrhizal species and their colonization determine the variation of physiological and morphological traits of roots. Here, we measured respiration rate of one lateral root segment and specific root length with different fungus species. Root respiration was positively correlated with mycorrhizal colonization across fungus species. Relationships between physiology and morphology have significant correlations and link with fungus species characteristics and their colonization. These results indicated that the changes of physiological and morphological traits of roots could associate with fungus species and their colonization.
