Growth stress, cell-wall deformation, slip plane


The relationship between fiber cell-wall deformations and longitudinal growth strain is investigated in trees of Eucalyptus pilularis Sm. (blackbutt) and Eucalyptus grandis W. Hill ex Maiden (rose gum).

In E. pilularis a weak correlation (r = 0.39) was observed between the number of cell-wall deformations in fiber walls adjacent to the second marginal ray cell and field measurements of longitudinal growth strain. However, a similar relationship could not be found in E. grandis.
