Sloan, John P. 1994. Root dipping of conifer seedlings shows little benefit in the Northern 

 Rocky Mountains. Res. Pap. INT-RP-476. Ogden, UT: U.S. Department of Agriculture, 

 Forest Service, Intermountain Research Station. 12 p. 



In the growth chamber, in the greenhouse, and in field studies, root dipping of bareroot 

 lodgepole pine, ponderosa pine, Douglas-fir, and Engelmann spruce seedlings did not im- 

 prove seedling survival, shoot growth, or root growth under dry soil conditions. Seedling 

 root growth varied with tree species, soil type, and type of root dip.
