Mean nitrogen content in red versus green L. japonica leaves. (A) Winter mean percent nitrogen content (±SE) at RR (ngreen = 5, nred = 5), WE (ngreen = 7, nred = 6), I40 (ngreen = 6, nred = 6), and combined means from all sites. Significant differences between red and green leaves denoted by asterisks (* p < 0.05; ** p < 0.01, *** p < 0.001, and **** p < 0.0001); (B) Mean percent leaf nitrogen (±SE) from leaf tissues collected at I40 during summer (nwinter-green = 6, nwinter-red = 6) and winter (ngreen = 6, nred = 6).
