Figure 1.

Effect of sex (female (red) vs. male (blue)) on the concentration of (a) soluble sugars (%); (b) starch (%); (c) total nonstructural carbohydrates (TNC; %); (d) total phenolic compounds concentration (TPhC; µmol/ g⁻¹ dry mass) in needles of Juniperus communis measured at eight time points over the course of two years. Asterisks indicate significant influence of sex (p < 0.05). Values for time points with a significant interaction between sex and soil fertilization treatment (fertilized F vs. nonfertilized NF) are illustrated in the inset.
