Abstract
Trees of rooted cutting and seedling origins of yellow cypress (Chamaecyparisnootkatensis (D. Don) Spach) were compared for survival and growth in two field experiments at 9 and 11 years after establishment. Experiment 1 evaluated seedlings and rooted cuttings from 1-, 3-, and 7-year-old donors. Experiment 2 compared rooted cuttings from 2-year-old donors and seedlings from the same 10 open-pollinated families. Survival was high in both experiments, with no significant differences between propagule types. In experiment 1, trees of rooted cutting origin from 1-year-old donors were significantly taller than trees of rooted cutting origin from 3- and 7-year-old donors, but there was no significant difference between trees of seedling and rooted cutting origin from any of the donor age 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. However, in this experiment, rooted cuttings had significantly fewer multiple tops than seedlings. It is concluded that the use of rooted cuttings is a viable alternative to seedlings in reforestation of yellow cypress.
