“…Not only had the container seedlings compensated for being significantly shorter initially, but they also had surpassed their bareroot counterparts . Owston and Seidel (1978) found that first-year height growth was best for bareroot ponderosa pine seedlings in Oregon, but after 5 years, the average height of container seedlings was greater. After 10 growing seasons, container seedlings generally were taller than bareroot seedlings .…”

Application . Survival and growth of ponderosa pine (Pinus ponderosa Dougl . ex Laws . var. ponderosa), Jeffrey pine (P. Jeffreyi Grev . & Balf .), and Douglas-fir (Pseudotsuga menziesii [Mirb .] Franco) seedlings were almost always higher if grown in containers and planted as plugs than planted as bareroot stock . If costs were similar, forest managers could consider using container stock on sites similar to those in this California study .Abstract . Ponderosa pine, Jeffrey pine, and Douglas-fir seedlings were planted in container or bareroot form at three elevations in northern California . At the lowest elevation (762 m), container seedlings of ponderosa pine were significantly taller than bareroot seedlings at ages 4 and 10, and had breast-height diameters that were significantly larger than bareroot counterparts at age 10 . Survival of Douglas-fir container seedlings was significantly greater than that of barefoot seedlings for all ages tested . At the mid-elevation site (1220 m), container seedlings of ponderosa pine and Douglas-fir were significantly larger in breastheight diameter than bareroot seedlings at age 10. Douglas-fir container seedlings survived significantly better at all ages than barefoot seedlings . At the highest elevation (1662 m), seedling height and diameter did not differ significantly, but survival of container seedlings was significantly higher than barefoot seedlings for both pine species at all ages tested .

“…In contrast, cutting roots of container-grown Pinus contorta vertically had no effect on percentage of acceptable seedlings for (Seaby and Schaible 2001). In other trials with no toppling, cutting roots reduced spiraling of roots (Persson 1978), improved the appearance of subsequent root growth (Bell 1978;Owston and Seidel 1978), and stimulated growth of geotropic sinker roots (Khurana 2001). Several root pruning trials have been conducted on container-grown pine seedlings.…”

When soil is moist and wind is at a gale force, the term used to describe blow down of old trees is windthrow. In contrast, toppling is a term used when planted pines lean more than 15° during the first decade after transplanting. Pines tend to topple more than other conifers and fast-growing species topple more than slow growing genotypes. Large areas of pine plantations have toppled before age 8 years. This paper describes some toppling events that have occurred in 18 countries and includes 16 questions about toppling.

“…Beginning in the late 1960s, field trials of container stock and comparisons with bare-root seedlings became part of the research effort. Early studies included a comparison of survival, growth, and root form of containerized Douglas-fir and noble fir (Owston and Stein 1978), how container and root treatments affected growth of ponderosa pine (Owston and Seidel 1978), and a regionwide effort to compare performance of bare-root and containerized seedlings (Owston 1990, Owston and. And, in British Columbia, the concerted effort to evaluate container seedling performance continued.…”

The Forest Service of the U.S. Department of Agriculture is dedicated to the principle of multiple use management of the Nation's forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research, cooperation with the States and private forest owners, and management of the National Forests and national grasslands, it strives-as directed by Congress-to provide increasingly greater service to a growing Nation.
