Study Notes
Strain and Stress
- Strain is the response to stress, which can be mechanical, thermal, or chemical.
Types of Strain
- Plastic strain is characterized by an irreversible physical or chemical change.
Drought Stress
- Water stress is a type of drought stress related to the availability of water for crops.
Physiological Changes due to Drought
- Drought can cause stomata to close, reducing CO2 uptake and photosynthesis.
- Drought can lead to a decrease in starch synthesis and an increase in soluble sugar concentration in green leaves, affecting carbohydrate metabolism.
