The comparative analysis between the juvenile and mature wood examined the diameter of vessels, the width and height of pith rays, and the number of vessels and pith rays per 1 mm2. The results show that the average vessel diameter, as well as the width and height of the pith rays reach statistically lower values in the juvenile wood than in the mature wood. On the other hand, no significant difference between the two woods has been found in terms of the frequency of vessels per 1 mm2. Having said that, the difference in the frequency of rays per 1mm2 between the juvenile and mature wood is far from negligible; the juvenile wood has three times as many pith rays as the mature wood. The density of the juvenile wood is higher (r12 = 726,07 kg/m3) than the density of the mature wood (r12 = 701,50 kg/m3)." . . "CZ - \u010Cesk\u00E1 republika" .
