چکیده
Many cultivars of ornamental conifers are difficult to propagate. Cuttings may root poorly and graft success may be highly variable even in the hands of skilled, experienced propagators. Because of these problems, we conducted a detailed study of the physiology of graft formation in Picea pungens 'Hoopsi' scions grafted on Picea abies rootstocks with the purpose of identifying factors limiting graft success and screening practical treatments designed to improve production.
