- Аннотация: The effect of VA-mycorrhization of corn plants by fungi of Glomus spp. on phosphorus metabolism has been studied. Phosphorus content in the VA-mycorrhizal corn root tissues increased by 35% for the species Glomus mosseae and by 98% for Glomus fasciculatum. Phosphorus was accumulated in the root tissues as low-molecular organophosphorus compounds of the acid-soluble fraction and high-molecular compounds of the acid-insoluble fraction (RNAs). Daily dynamics of phosphorus transfer to the above ground parts of the mycorrhizal corn plants depended on the stage of plant vegetation: by the 60th day phosphorus carry-over was predominantly as orthophosphates, whereas the 70-day-old corn plants showed a significant increase of the organophosphorus content in the daily root exudate. Phosphorus nutrition of corn plants has been shown to be an essential factor of biosynthetic processes in the plant. Root infection by VAM fungi has greatly improved the phosphorus uptake, translocation and its subsequent transfer through the host plant.
