| Abstract: | The root systems of all plants adapt to soil conditions. One of the ways Norway spruce adapts is a regulation of absorbing root surface area, which can be viewed as an ecomorphological index of soil conditions. Minimal specific root surface area of absorbing roots of Norway spruce (28–29 m2kg−1) responds to optimal soil conditions. This was achieved at a soil bulk density of about 1.2 gcm−3. |
