Study Notes
Propagation
- A method of plant reproduction by cutting off segments of leaves, stem, or roots and placing them in growing media to develop into new plants.
Macronutrients
- Nitrogen (N), Phosphorus (P), and Potassium (K) are required by plants in relatively large amounts.
- Nitrogen is a primary macronutrient, essential for leaf growth and chlorophyll production.
- Calcium (Ca) is a secondary macronutrient, crucial for cell wall strength and root development.
- Primary nutrients are often lacking in soil due to depletion through plant uptake and leaching from the soil.
Plant Nutrients
- Phosphorus is a key nutrient found in fertilizer, contributing to root development, flower production, and seed formation.
Layering
- It involves encouraging root growth on a stem while it is still attached to the parent plant.
- This method promotes the development of a new plant from the stem, while still connected to the source of nutrients.
'NPK'
- Represents the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) found in fertilizers.
Germination
- The process of a seed developing into a plant.
Sexual Reproduction
- Pollen grains, containing the male gametes, are transferred to the stigma of the flower (female part) during the pollination process.
Vegetative Reproduction
- This method involves producing new plants from parts of a plant like leaves and stems, creating genetically identical clones.
Scarification
- This process helps to break down the hard seed coat, facilitating water absorption and successful germination.
Cross-Pollination
- Some plants require pollinators like bees and butterflies to transfer pollen between flowers for fertilization.
Division
- This technique refers to splitting apart a root or root system into two or more pieces, each of which can develop into a new plant.
Plant Breeding
- It involves the deliberate control and manipulation of plant reproduction to produce new varieties with specific traits.
Pollination
- Also known as the transfer of pollen grains from the male part of the flower (anther) to the female part (stigma).
