Abstract | Since seedlings represent future forests, they are an important population for exposure studies. The experimental conditions for seedling studies cover a wide range of treatment combinations, facilities, and exposure regimes. The experimental utilization of experimental studies with tree seedlings requires the appropriate design and statistical concepts employed with any population response study. These issues are reviewed for their relevance to exposure studies and contribution toward studies of forest/tree response to pollutants. In order to realize the potential strengths of these studies and further enhance the intrinsic value of seedling research, the planning of experiments should include both the relevant population of interest and an explicit definition (a priori) of all response variables and covariates. The experimental designs should provide for pretreatment measurements, repeated measures within growing seasons, and treatments or measurements which span more than one growing season. |
