β£
- Asexual reproduction in plants
β£
β£
β£
- Runner shoots
β£
- Horizontal stems that grow above ground along the surface of the soil from which new plants will grow from
β£
- Axillary/lateral buds on the stem
β£
- Adventitious roots
β£
- Strawberry plant
β£
β£
- Root tubers
β£
- When fibrous roots become swollen with food
β£
- New plants grow from the axillary buds on the swollen root
β£
- Dahlia
β£
β£
- Bulbs
β£
- Short swollen underground stem
β£
- The apical or axillary bud can give rise to bulbs from which new plants can form
β£
- Onions
β£
β£
- Mother leaf grows plantlets/smaller leaves on itself
β£
- When they detach from mother leaf and land on the ground, new plants can grow from them
β£
- Mother of thousands
β£
β£
β£
- Cut off a section of a stem of a plant
- Dip the cut end into rooting powder to stimulate root growth
- Plant the stem and it will grow into an identical plant as the parent
β£
β£
- Combining the desired features of two different plants
β£
- If you have a tree with great shoot system but has a poor root system
- Graft a better root system from a different plant onto the tree
β£
β£
- Take the stem of the parent plant and pin it beneath the soil (no not detach the stem from original plant)
- The part of stem beneath soil will develop a root system
- Part of the stem above the soil will develop a shoot system
- Eventually when the stem grows its own fully developed root system it can be detached
β£
β£
- Tissue culturing
β£
- Plant tissue is obtained from parent plant
- Plant tissue is placed in a sterile growth medium
- A callus of cells forms
- This callus of cells is treated with growth regulators to stimulate root and shoot growth
- Eventually a plantlet forms
β£
- A mass of undifferentiated cells
β£
- There are no seeds produced in vegetative propagation
1. There are seeds produced in sexual reproduction
- There is no fertilisation in vegetative propagation
2. There is fertilisation involved in sexual reproduction
- All offspring is genetically identical in vegetative propagation
3. Offspring has genetic variation in sexual reproduction
- Vegetative propagation is a fast process
4. Sexual reproduction is a slow process/may not occur
β£
- There is no variation so plant reserves its desirable features
- It is a fast process
β£
- Plant is more prone to disease
