A concise overview of temperate fruit tree rootstock growth causes is provided, alongside key propagation techniques. Recently, attributes like pest and disease resistance, tolerance to adverse climates, and the ability to dwarf the scion have become more important than ease of propagation when selecting clonal rootstocks. This shift is due to advanced propagation methods that allow for the cultivation of resistant clones. However, these novel techniques can lead to partial rootstock renewal, and micropropagated rootstocks may show increased burr knotting and frequent suckering, presenting challenges in their use.
