Notes and Observations: Dwarf Shoot Proliferation in Red Pine

Key Points

• Only early June treatment effectively increased dwarf shoots in 15-year-old red pines, while older trees showed less response.
• Results indicate that shearing may not significantly enhance scion supply from dwarf shoots in older red pines.
• The study suggests that promotion of dwarf shoot meristems works primarily in younger red pine trees.
• Shearing can be an effective method for increasing shoot proliferation, but its efficacy diminishes with tree age.
