The wood samples of 9 triploid clones of Populus tomentosa were cut from 9-year-old clonal stand. The oven- and air-dried samples were used to study their genetic variation in shrinkage. The results indicated that there were significant differences between clones and all the coefficients of shrinkage were found to be under strong genetic control. The vertical variation pattern within tree of shrinkage was downward with the three height.
