The influence of seed origin on stand variables of Scots pine (Pinus sylvestris L.) in European Russia according to long-term observations

Scots pine is one of the most widespread tree species in Eurasia, which determines its confinement to different growing conditions. The origin of the planting material influences the variables of forest stands. According to the data of long-term experiments in the Forest Experimental District of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, it was revealed that the most promising are the stands grown from seeds of local origin. Such stands are characterized by maximum wood quality, durability and productivity.
