From: Moderate salt treatment alleviates ultraviolet-B radiation caused impairment in poplar plants
The effects of ultraviolet-B radiation (UV-B), salinity stress and their combined treatments on the concentrations of flavonols and anthocyanins in leaves of two Populus species (P. alba and P. russkii). (a) Flavonols concentration of P. alba; (b) Flavonols concentration of P. russkii; (c) Anthocyanins concentration. Data shown are the average mean ± SE of three replicates (n = 3). Different letters in the same font-style (non-italic and italic) indicated statistical significance at the P < 0.05 level among different treatments according to Tukey’s test.
