Fig. 6 2019 recovery growth rate (measured at the end-season 2019) in relation to pre-winter and post-winter NSC in shoots and roots of oak (Quercus petraea ) and beech (Fagus sylvatica ) saplings treated with four drought durations in 2018 and well-watered in 2019. In case there is a significant (p < 0.05) relationship between growth and NSC level for the pooled data, a fitting line is given.
