Height (cm) by measurement date for five pine seedling types grown over 13 months in greenhouse conditions. The repeated measures ANOVA for height was significant by time (F = 1691.4; p < 0.01), species type (F = 394.3; p < 0.01), and their interaction (F = 191.7; p < 0.01). There were significant differences in height between species types in August (F = 673.6; p < 0.01), January (F = 551.5; p < 0.01), and May (F = 22.8; p < 0.01). (JPEG 2272 kb)
