A relation was found between the alkylresoroinols content and the weight of single grains, their specific weight and situation in the ear. In the group of grains with high specific weight (above 1.300 g/cm3) the relative alkykesorcinols content proved to be a constant value, whereas the total content was positively correlated with the grain weight. A negative correlation was found between the specific weight and the relative alkylresorcinols content decreasing from tip to base of ear. In the apical zone of growth grains with low specific weight (below 1.260 g/cm3) constitute 70 per cent, and in the middle and base of the ear 30 per cent of all grains in the given zone.
