Seasonal growth dynamics of Siberian spruce ectomycorrhiza and sugar content in it

Seasonal growth dynamics of Siberian spruce ectomycorrhiza and sugar content in it Seasonal growth, dynamics of morphological and anatomical structure, and sugar content in ectomycorrhizal roots of Siberian spruce (Picea obovata Ledeb.) were studied. A variability of the root tip structure related to variations in hydrothermal conditions in soils of spruce phytocenoses was observed. A high content of mono- and disaccharides was detected in root tips in the beginning and end of the growth season. Changes in the growth pattern of spruce mycorrhizal roots were associated with changes in the sugar concentration in them, the thickness and volume of the mycelium sheath, and respiration. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

Seasonal growth, dynamics of morphological and anatomical structure, and sugar content in ectomycorrhizal roots of Siberian spruce (Picea obovata Ledeb.) were studied. A variability of the root tip structure related to variations in hydrothermal conditions in soils of spruce phytocenoses was observed. A high content of mono- and disaccharides was detected in root tips in the beginning and end of the growth season. Changes in the growth pattern of spruce mycorrhizal roots were associated with changes in the sugar concentration in them, the thickness and volume of the mycelium sheath, and respiration.
