Sum of temperatures above 10ºC and the quality classes of Scots pine stands in the latitudinal gradient (according to Volosevich 1984). * – numbers indicate relative values (latitudinal growth coefficient), the columns – the sum of the temperatures above 10ºC, the line – the quality classes

Figure 2

Growth of Scots pine provenances in 31-year-old provenance tests in the Arkhangelsk and Vologda regions: the up arrow shows the progenies transfer direction from the original stands to the test plots from north to south (imitation of warming). The down arrow indicates transfer from the south to the north (imitation of cooling); provenance numbers according to Table 1
