Carbohydrate absorption by roots of Pinus taeda

Abstract

A laboratory experiment demonstrated that mycorrhizal fungi are able to produce soluble carbohydrate from cellulose in sufficient quantities to support the growth of seedlings of Pinus taeda in sand culture in the absence of photosynthesis, and also that maltose in the absence of mycorrhizas can, as a soil nutrient, substitute for photosynthetic activity to some extent.
