Effects of Irrigation Frequency and Grit Color on the Germination of Lodgepole Pine Seeds
Pinto, J. R., Dumroese, R. K., and Cobos, D. R. USDA Forest Service, Rocky Mountain Research Station, Proceedings RMRS-P-58. p.52-57. National Proceedings: Forest and Conservation Nursery Association - 2008. 2009.
Nursery cultural practices during germination can be highly variable between existing production facilities. Although nursery guidebooks suggest keeping seeds moist, there are no known scientific answers indicating what sufficient moisture levels are. This study objective was to characterize differing irrigation regimes and grit color choices on different germination parameters (Germination Capacity, GC; Peak Value Germination, PV; Germination Value, GV; and Germination Rate, GR50) using seedbed temperature and soil matric water potential (Ψ) measurements.
