Abstract
One-year-old plants of the apple rootstocks MM. 106 and M.7 were allowed to assimilate 14CO2 in autumn, spring and summer and the distribution of the tracer within the plant over a growing season was followed. In MM.106 distribution of the tracer in two fractions of extractable carbohydrate and the residues representing structural material, was determined. The results of the radioactivity assay are discussed in relation to seasonal patterns of assimilate supply and demand in the different regions of the plant.Keywords
