Fruit tree rootstocks

Fruit tree rootstocks are specific, but fruit species related root part of the plant on which the other plant, a scion or bud of specific fruit variety is connected by means of grafting or budding to make what is usually called a commercial fruit tree.

In a true sense, the rootstock is a mediator between the soil and the fruit variety controlling the trunk and branch development and directing the energy into the development of fruits.

Besides the effect on the physiology of the fruit it carries, rootstock also helps the specific variety adapt to environmental conditions and the growing system.

Rootstocks are used to determine and effect

  • Rooting and development of roots of plants
  • Adaptation to different soil types and adequate exploitation of organic and inorganic substances from soil
  • Resistance and hardiness of plants to biotic and abiotic factors
  • Vigor and size of the plant
  • Vegetation period, flowering period, and yield
  • The quality of the fruit

Main types of producing rootstocks are

  • Vegetative rootstocks - Rootstock produced from shoots or scions of a specific clone carrying its identical (parental) characteristics. Widely used in the production of commercial trees.
  • Generative rootstocks - Reproduced from the wild types and seeds of wild varieties. Generative rootstocks have better rooting but they can have differences in the uniformity of growth.


Apple vegetative rootstocks:

  • Extremely dwarfing rootstocks: A2, P22
  • Dwarfing rootstocks: M9 T337, M9 FL56, M9 RN29, M25, M26, M27, P16, P60, B9 (winter hardy)
  • Semi-dwarfing rootstocks: MM106, MM106 9a, MM111, M4, M7
  • Vigorous rootstocks: M11
  • Following calibration: 4/5, 5/7, 7/8, 8/10, 10/12, 12/14 millimeters, and other
