Abstract

Seven years' observations on 1375 grafts of 8 combinations of Pine species under forest conditions are given (Pinus strobus, P. peuce, P. koraiensis, and P. cembra scions on P. strobus rootstocks, and P. resinosa, P. peuce, P. koraiensis, and P. cembra scions on P. resinosa rootstocks). In general, growth, survival, and cone production for interspecific grafts were superior on P. strobus rootstocks. There was marked clonal variation in the intraspecific grafts; in the case of P. strobus, survival was higher on younger rootstocks and flowering on older ones. It is concluded that grafting is a practical means of propagating all 5 of the species studied.
