Study Notes
Vegetative Reproduction
- Vegetative reproduction retains biological traits of the mother plant (e.g., shape, leaf structure, flower color).
- Common in ornamental plant cultivation, allowing propagation from stems, leaves, and roots.
- Essential for many tropical plants that do not produce seeds in temperate climates (e.g., aloe, ficus, monstera).
- Maintains valuable varietal traits accumulated through centuries of cultivation.
- Plants propagated vegetatively bloom sooner than seed-grown counterparts.
Methods of Vegetative Reproduction
- Various techniques include stem and leaf cuttings, bush division, offspring, layering, and whiskers.
- Stem cuttings are the most frequent method: young or semi-woody shoots (6-8 cm long) are ideal.
- Cuttings should have 2-3 internodes and 3-4 leaves. Larger leaves may need to be trimmed to reduce water loss.
- For plants like potatoes, middle parts of shoots with a node can be used when planting material is scarce.
Preparing and Planting Cuttings
- A sharp knife should be used to make cuts, with the lower cut at an angle just below a leaf or node.
- After cutting, some plants (e.g., milky sap plants) are placed in warm water briefly.
- Hard-rooting cuttings may benefit from growth hormones like aloe juice or sodium humate.
Rooting Conditions
- Cuttings require moist conditions, typically planted in sandy soil with good drainage.
- They should be regularly misted with water and covered to maintain humidity.
- Optimal temperature for rooting is 20-25 °C, taking 2-4 weeks for roots to develop.
Post-Rooting Care
- Gradual adaptation of rooted plants to greenhouse conditions is essential; initially covering glass should be removed gradually.
- Plants should be transferred into pots with soil appropriate for their growth stage, ensuring good drainage.
Additional Propagation Techniques
- Division of bushes is a spring method typically used for strawberries, which produce "whiskers" that can develop roots.
- Air layering involves making a cut on a branch and wrapping it to encourage root growth before severing and planting.
- Tubers can undergo accelerated reproduction through techniques like shadow sprouts, where multiple new plants can emerge from a single tuber.
Managing Sericulture and Disease
- Variety renewal is crucial to preserve the qualities of crops as tubers may degenerate over time or transmit diseases.
- Healthy planting materials promote stable productivity and prevent the decline associated with diseases such as scab and black leg.
- Tuber selection and sprouting procedures should be maintained carefully to ensure crop integrity.
Timing and Environmental Conditions
- Optimal times for transplanting and propagation are during the spring months (March to May).
- Conditions for sprouts or seedlings include proper humidity, temperature, and shading initially to prevent desiccation.
- Planters should ensure soil is rich in organic materials and periodically moist to support seedling growth and health.
Harvesting and Planting Seedlings
- Separation and planting of sprouts occur meticulously, ensuring proper depth relative to sprout length.
- Seedlings are typically ready for field planting several weeks after initial sprouting, with careful monitoring necessary to promote growth.
- Adequate spacing (e.g., 70 x 20 cm) should be maintained during sowing to ensure healthy growth and development.
