Study Notes
Propagation Environments
- Propagation can occur in open air or in controlled environments
- Open air propagation is uncontrolled
- Controlled environments include greenhouses, nurseries, shadehouses and laboratories
- Controlled environments allow for manipulation of environmental conditions
Optimizing Propagation Efficiency
- Environmental conditions and infrastructure can enhance propagation efficiency
- Humidity, light, temperature, and gas exchange are crucial factors
- These conditions influence plant development
Microclimatic Environmental Conditions
- Light: Plays a vital role in plant growth and development
- Relative Humidity: Affects plant water balance and transpiration
- Temperature: Impacts plant growth and development, as well as physiological processes
- Gaseous Exchange: Essential for photosynthesis and respiration
Building Conditions
- Substrate: Provides physical support and nutrients for plants
- Mineral Nutrients: Essential for plant growth and development
- Water: Required for plant growth, hydration, and nutrient uptake
Biological Interactions
- Interactions between propagules and other organisms can be beneficial or harmful
- Beneficial organisms include mycorrhizal fungi and nitrogen-fixing bacteria
- Harmful organisms include pathogens and pests.
