Carbohydrates and secondary compounds of alpine tundra shrubs in relation to experimental warming

BMC Plant Biology

Table 2 The statistical results of the effects of treatment (warming and control), sampling dates (July, August, September) and species (Dryas octopetala var. asiatica, Rhododendron confertissimum and Vaccinium uliginosum) on the soluble sugars, starch and total nonstructural carbohydrate (TNC) (sugar + starch) concentrations, the ratio of soluble sugars to starch, and secondary compounds (flavonoids, total phenols, triterpene) concentrations in leaves using three-way ANOVA
