Figure 4. Mean biomass and pool size of non-structural carbohydrates (NSC) at individual and stand level (both n = 6) of Quercus aquifolioides shrubs grown at 3000, 3500, and 3950 m a.s.l. on a SE-facing slope of Mt. Zheduo, SW China.

Figure 4

Different letters indicate statistically significant differences (p<0.05) in biomass or NSC pool size among elevations. Standard errors bars (+1SE) are given for the total above- or below-ground biomass or the total above- or below-ground NSC pool size.
