Frost resistance during shoot elongation in Picea abies seedlings in relation to the growth environment of the previous growing period.
Frost resistance during shoot elongation in seedlings of Norway spruce ( (L.) H. Karst.) was studied in two experiments. The aim of the first study was to evaluate the effect of varying mineral nutrition. Except for potassium, only minor differences in mineral elements concentrations were...
