Table 6.
Photosynthetic pigment and tocopherol contents for Q. coccifera leaves expressed per leaf area or per total chlorophyll content from the Mediterranean (MED) and temperate (TEM) sites. Data are mean ± SE. Different letters indicate statistically significant differences (P < 0.05) between sites. Chl, chlorophyll; Neo, neoxanthin; Lut, lutein; β-Car, β-carotene; α-Toc, α-tocopherol; VAZ, violaxanthin-cycle total pool; AZ/VAZ, de-epoxidation state of the violaxanthin-cycle pigments.
