摘要:

Site index was calculated for 66 experimental plantations in western Canada and northern Sweden, containing a wide range ofPinus contortaprovenances drawn from seed lots belonging to the IUFRO international provenance testing program. Growth data from recommended provenances were used to calculate the site index. Site index was defined as predicted average height of the 100 largest trees by diameter ha‐1at age 50.
