Abstract Increasing incidence of the poplar-and-willow borer (Cryptorhynchus lapathi) in Pacific Northwest hybrid poplar plantations has resulted in reduced wood quality and stem breakage. Three replicated, 5-yr-old clone trials established in the vicinity of Pullman, WA were rated for host attack preference. Attacks by C. lapathi were found to be significant for plantation, clone, and the clone by plantation interaction. Attack rating among clones was affected by genotype. Those clones possessing P. nigra parentage, including Lombardy poplar, OP-367, and PC-6, showed significantly lower attacks across all plantations. Within the P. trichocarpa × P. deltoides (TD) hybrids, both 58-280 and 50-194 consistently exhibited lower attacks compared to the remaining four TD hybrids. Plantation, clone, and the plantation by clone interaction affected tree growth parameters significantly. Mean clone stem volume across sites from largest to smallest was: 49-177, OP-367, 50-197, 52-225, PC-6, 50-194, 58-280, 15-29, and Lombardy poplar. Attempts to correlate attack rating with any parameter of tree size were unsuccessful. Combining growth data and attack rating, OP-367 would be recommended for planting in arid regions east of the Cascade Mountains, followed by PC-6, 50-194 and 58-280. Future hybrid poplar breeding for this region should consider P. nigra as a parent. West. J. Appl. For. 18(4):276–280.

The hybrid poplar plantation management systems and objectives, some of the problems, and the results of work to date are summarized.Short-rotation poplar plantations are of regularly spaced traditional-size trees, intensively managed in monoculture. Silvicultural problems are associated with clonal selection, site selection and treatment, spacing, and planting stock type. The mean annual increments of best varieties have reached at 12 years of age 29 m3/ha (400 cu. ft./acre).Forest type poplar plantations are established in logged forest areas. These are less intensively managed.Fast growing poplar and associated shade tolerant hardwoods and conifers are planted in mixed plantations (poplar polyculture) on highly variable sites. Beneficial influences are apparent on the stem quality and phenology of associated trees. Growth stimulating effects, increased site utilization and disease resistance are expected.In mini-rotation system, average dry yields of 8 t/ha/a (3.5 tons/acre/yr) or more are produced in closely-spaced, intensively-managed 1- to 3-year-old coppice plantations. Pulping tests indicate satisfactory qualities. In addition, many other uses, from petrochemical replacement to food, have potential. The management problems under study are: clonal selection, site treatments, spacing, and mechanization.
