    Description

    Field tests with control (C), root-dipped (D), jellyrolled (J), and jellyrolled and acclimatized (J + A) bare-root seedlings were conducted at 14 sites in Oregon and Washington in 1984. Nine tests were conducted with ponderosa pine, four with Douglas-fir, and one with lodgepole pine. A separate test with ponderosa pine and Douglas-fir was conducted in Washington in 1983. In the 1984 test, average values of survival for ponderosa pine for the C, D, J, and J + A treatments were 82,86,85, and 87 percent, respectively. The increases in height were 16,18,17, and 15 percent, respectively..Survival of the J + A seedlings was significantly higher than that of C seedlings, but other differences among treatments for survival or growth were not significant. For Douglas-fir, average values of survival for the C, D, J and J + A treatments were 77, 72, 74, and 70 percent, respectively; height growth was 18, 19, 17, and 18 percent, respectively, with no significant differences. Survival of lodgepole pine was 99 percent for all treatments, and height growth ranged from 28 to 34 percent.
