Fig. 1From: Amelioration of planting stress by soil amendment with a hydrogel–mycorrhiza mixture for early establishment of beech (Fagus sylvatica L.) seedlingsEffect of planting stress on bud burst of young beech trees (F. sylvatica). The trees were planted on the 8th or 9th of March after exposure of the bare-rooted seedlings to air for 0, 2, or 6 h, respectively. Half of the seedlings were planted into the soil amended with a hydrogel–EMF mixture (+A). A tree was scored as flushed, when the first leaf was visible at the top of the budBack to article page
