In two nursery species important for European forests and landscape, Quercus robur and Fagus sylvatica, the impact of spacing in the seedbed on morphological characters such as height, dry weight, number of first-order roots and first-order branches (only beech) was assessed after two-years Height, dry weight of shoot, root, dry weight ratio between root and shoot and percentage of seedlings with six or more first order roots were all negatively affected at lower spacing Subsequently the effect of spacing on early field performance was deter mined after transplanting for two years in competition with grass and without irrigation and fertilisation simulating conditions m a forest The initial differences between spacings in relation to dry weight were still present after two-years of transplanting Height increment was small in oak and substantial in beech, but the initial differences in height between spacings were more or less maintained after transplanting
