Study Notes
Conditions of Propagation
- Propagation can take place in open sky or controlled environments
- Open sky offers minimal environmental control
- Controlled propagation includes managing variables such as the atmosphere, soil, and nutrient levels
Improved Efficiency
- Managing atmospheric conditions can improve propagation efficiency
- Optimal propagation occurs under ideal microclimatic conditions
- Soil (edaphic) conditions are crucial for successful propagation
- Choosing the right substrate, water, and mineral nutrition is important
- Biological factors can also affect propagation success
Light (Luz)
- Light fuels photosynthesis, a vital process for plant growth
- Light is necessary for root development, seed germination, plantlet growth and stem elongation
Aspects of Control
- The quantity and intensity of solar radiation significantly impacts propagation
- Artificial light in greenhouses complements natural light
- Photoperiod, or the duration of light exposure, is critical
Number of Daylight Hours
- Different plants have distinct photoperiod needs
- Long-day plants flower when daylight hours increase
- Short-day plants flower when daylight hours decrease
- Neutral plants flower based on other stimuli, not photoperiod
- Intermediate-day plants require specific daylight hours for flowering
