Effects of Crown Position and Plant Age on Jack Pine Long-Shoot Cuttings

Rooting success of long shoot cuttings of jack pine— Pinus banksiana Lamb.— was found to be influenced by crown location effects among 5-to 30-year-old trees. Despite some variation in response, mid to lower crown cuttings generally rooted more readily than upper crown cuttings. The highest rooting frequencies observed for 4-, 5-, 6-, 7-, and 10-year-old trees ranged from 45 to 75%, whereas cuttings from 30-year-old trees rooted at 28%. These results are encouraging in light of the general perception that jack pine is difficult to propagate by rooted cuttings, and they suggest that operational asexual propagation may be feasible.
