Abstract
WHEN young apple trees assimilate nitrogen, reserve materials are generally laid down in the tissues of the stem and root1. Only part of these nitrogenous reserves can be extracted from the stem by exhaustive treatment with 70 per cent (v/v) aqueous ethanol, and a study has recently been made both of the nature of the reserves and of their extraction from the tissues by different solvents.
