| Breeding method | Characteristic | Example |
Creeping shoots | In places of contact of elongated shoots with the ground, adventitious roots are formed. After a while, the old shoots die off at the base and the plant becomes independent. | Strawberry, clover, meadow tea, ivy budra, veronica officinalis, cranberry |
Rhizomes | On the rhizomes (modified shoots), young shoots are formed from the buds | Wheatgrass creeping, lily of the valley, anemone, blueberry, lingonberry, iris, daisy, meinik, runny |
Tubers | The tubers are separated from the stolons.
Aerial shoots develop from the apical and lateral buds, on which adventitious roots are formed |
Potatoes,
Jerusalem artichoke, neat |
Bulbs | From the lateral buds on the mother’s bulb (modified shoot), “babies” are formed – daughter bulbs | Wild onion, tulip, hyacinth |
Leaves | Parts of the leaf blade of some plants may separate from the mother plant and fall to the ground. Adventitious roots are formed on the separated part | Meadow core |
Root offspring | On the roots of some plants, buds can form, from which shoots grow – root suckers | Lilac, aspen, cherry, thistle, sow thistle, fireweed |
Brood buds | On the leaves of the plant, special brood buds are formed, which subsequently fall to the ground and take root | Bryophyllum, fern aspelenium viviparous |
Shoot cuttings | A stalk with 3-4 leaves or buds is cut from an adult plant. The cuttings are placed in a container of water or planted in moist soil. After a while, adventitious roots form on the cuttings | Tradescantia, geranium, currant |
Layers | The lower branches of the plant are pressed to the ground, the lower part of the shoot is pinned to the soil and covered with damp earth. When adventitious roots are formed on the layer, the shoot is cut off from the mother bush and transplanted | Gooseberries, currants, viburnum, phlox |
Leafy
cuttings |
Cut off leaves or parts of leaf blades are planted in moist soil. After a while, adventitious buds and adventitious roots appear on them. | Begonia, Saintpaulia (Usambara violet), Sansevier |
Root
cuttings |
A root cutting is cut from an adult plant (a root segment is 15-25 cm in length). When planted in soil on a root cuttings, aerial shoots develop from adventitious buds | Raspberry, blackberry |
Vaccination
(transplantation) |
A bud-eye or stalk of a cultivated plant (scion,) is spliced with a wild stalk (stock) | Forest apple, pear, hawthorn, rosehip |
Tissue culture | Small pieces of plant tissue (it is best to take educational tissue) or individual cells are placed in sterile conditions on a special nutrient medium and create favorable conditions (optimal temperature, humidity, illumination). After a while, small rudiments of young plants are formed from individual cells. | Rare, especially valuable plants, which cannot be reproduced in any other way |
