Study Notes
Drought Tolerance in Plants
- Drought tolerance involves complex pathways, allowing plants to respond to specific conditions.
- The type of mycorrhizal association formed in plant roots can influence how quickly plants adapt to drought from an evolutionary perspective.
Plant Adaptations
- Some plants have natural adaptations to dry conditions, such as drought tolerance, detoxification, and repair of xylem embolism.
Protective Mechanisms
- Soluble compounds like sucrose, glycine, and proline can intervene to aid plant survival.
- ROS-scavenging enzymes also play a role in protecting plants.
Genetic Engineering
- New varieties of crops like corn, wheat, and rice have been created through genetic engineering to improve drought tolerance.
Horticulture
- Horticulture is not limited to the cultivation of food crops like fruits and vegetables.
- Horticulture involves more than just the use of hand tools like digging sticks, hoes, and carrying baskets.
- Anthropologists do not view agriculture as a less intensive strategy compared to horticulture.
- Horticulture encompasses landscape and garden design, construction, and maintenance.
- The study and practice of horticulture date back to ancient times.
