The M 9 T 337 rootstock ensures a semi-dwarf growth habit for trees, which typically reach 2.5–3 meters in height. It facilitates early entry into production for grafted varieties in the 2–3 year and increases productivity, while also influencing the improvement of fruit size and coloration.
The root system of the rootstock is shallow and brittle, which requires trees to have permanent supports installed for their entire lifespan. The plant is sensitive to drought and waterlogging, requiring regular irrigation. In general, M9 group rootstocks are prone to infestation by woolly apple aphid and fire blight.
