The rootstock is very susceptible to fire blight and can develop burr knots. [3] M.25: Very vigorous — Suitable for a grassed orchard, and to grow on as a full standard. Plant 20 ft (6.1 m) apart, makes a tree of 15 to 20 ft (4.6 to 6.1 m) or more height and spread, eventually yielding 200 to 400 lb (91 to 181 kg) per tree.
Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts.
A method of grafting white spruce of seed-bearing age during the time of seed harvest in the fall was developed by Nienstaedt et al. (1958). [20] Scions of white spruce of 2 ages of wood from 30- to 60-year-old trees were collected in the fall and grafted by 3 methods on potted stock to which different day-length treatments had been applied ...
Malling-Merton 106 rootstock is slightly smaller than MM 111, but is a very productive tree and has early fruiting abilities. [11] It is a great rootstock to be used in a variety of soil conditions because it is very hardy with moderate vigour. [11] This rootstock must be planted in well-drained soils as it is susceptible to collar rot. [11]
Asexual methods are most often used to propagate cultivars with individual desirable characteristics that do not come true from seed. [6] Fruit tree propagation is frequently performed by budding or grafting desirable cultivars , onto rootstocks that are also clones, propagated by stooling.
Layering is a vegetative propagation technique where the stem or branch of a plant is manipulated to promote root development while still attached to the parent plant. Once roots are established, the new plant can be detached from the parent and planted. Layering is utilized by horticulturists to propagate desirable plants.
The tuber is produced in one growing season and used to perennate the plant and as a means of propagation. When fall comes, the above-ground structure of the plant dies, but the tubers survive underground over winter until spring, when they regenerate new shoots that use the stored food in the tuber to grow.
In some plants, seeds can be produced without fertilization and the seeds contain only the genetic material of the parent plant. Therefore, propagation via asexual seeds or apomixis is asexual reproduction but not vegetative propagation. [6] Softwood stem cuttings rooting in a controlled environment. Techniques for vegetative propagation include:
