Fig. 3From: Effect of light regime and provenance on leaf characteristics, growth and flavonoid accumulation in Cyclocarya paliurus (Batal) Iljinskaja coppicesVariation in total and selected flavonoid accumulation in leaves of Cyclocarya paliurus per plant among various treatments (mean ± SD, samples collected in October 20, 2011). Different lower case letters indicate significant differences among various treatments within the same flavonoid (p < 0.05 by Tukey’s test).
