COMPARISONS OF YELLOW CYPRESS TREES OF SEEDLING AND ROOTED CUTTING ORIGINS AFTER 9 AND 11 YEARS IN THE FIELD

In experiment 1, Chamaecyparis nootkatensis trees of rooted cutting origin from 1-yr old donors were significantly taller than trees of rooted cutting origin from 3- and 7-yr old donors, but there was no significant difference between trees of seedling and rooted cutting origin from and of the donor groups. Experiment 2 found no significant differences between trees of rooted cutting and seedling origin in height or diameter, and no significant differences between families, though rooted cuttings had significantly fewer multiple tops than seedlings. Use of rooted cuttings is thus a viable alternative to seedlings in reforestation of yellow cypress. -from Authors
