Principal component analysis (PCA) presenting the relationships between selected sugar beet physiological parameters depending on the cultivar (Viola—yellow triangle, Jaromir—blue star, and Pulitzer—green circle) and month of the growing season. Abbreviations: A—CO2 assimilation, E—transpiration rate, Ant—anthocyanins content, Chl—chlorophyll content, Flav—flavonol content, Cerco—severity of CLS infection, GLAI—Green Leaf Area Index, Glu—glucose content in leaves, Fru—fructose content in leaves, Sach—sucrose content in leaves, Polar—polarisation (root sugar content), φP0—maximum quantum yield of photosystem II, ET—electron transport flux per leaf excited cross-section, RC—% of active reaction centers per leaf cross-section.
