A mean number of fertile scales was 88,6% and 11,4% of sterile ones in a cone. A specificity of A. alba cone structure has been revealed, lying in the presence of a transition zone between the fertile and sterile layers and comprising seeds, not having reached the normal size compared to seeds from the fertile layer, and conventionally termed by us ‘undersized’. They averaged to 16,8% of the general number of seeds in a cone, a number of seeds of a normal size (‘fullsized’ ones) being 83,2%. Further analysis of empty and full-grained seeds will allow to define tree specimens, which could serve a source of the seed material for the silver fir forests reproduction. |
