Allocation (mean % ± SD, <i>n</i> = 5) of nutrients and mobile carbohydrates within a <i>Quercus variabilis</i> seedling grown in different geographical locations and in a common garden in China.

ND = northern distribution, Zhuang-He in NE China; MD = middle distribution, He-Feng in central China; SD = southern distribution; An-Ning in SW China; No letters indicate non-significant difference, and different letters indicate significant difference at p<0.05 level for each parameter in each tissue type among the three locations within each experiment (i.e. in situ or ex situ).
