Effect of ring width on cell wall area in Populus alba L. juvenile wood

Nowadays, white poplar (Populus alba L.), as a fast growing species, has a great breeding potential, due to its adaptation to climate changes and changed ecological conditions. For the purpose of this research, a total of ten trees from two sites along the Drava river in Croatia were selected and harvested. From each tree, five annual growth rings within juvenile wood were selected. Ring width (mm) was measured and cell wall area (%) was calculated as a percentage remain after detracting fibre lumen area, vessel lumen area and ray area. Relationship between cell wall area and ring width was analysed. As a result, statistical analyses indicated weakly negative correlation between cell wall area and ring width in juvenile wood of both Populus alba L. natural populations. Overall, no significant effect of growth rate on cell wall area was determined.
