Drought-Resistant Crops
Agricultural plant varieties specifically developed or selected for their ability to survive and produce yields under water-scarce conditions.
Drought-Resistant Crops
Drought-resistant crops represent a crucial advancement in agricultural adaptation, combining traditional breeding methods and modern genetic engineering to create plants that can thrive with limited water resources.
Biological Mechanisms
These crops employ several key survival strategies:
- Deep root systems that access underground water
- Modified leaf structures that reduce transpiration
- Enhanced cellular mechanisms for water retention
- Osmotic regulation adaptations
- Accelerated growth cycles to mature before drought periods
Major Types
Traditional Varieties
- Sorghum - naturally drought-tolerant cereal
- Millet - requires minimal rainfall
- Cassava - survives in arid conditions
- Tepary beans - desert-adapted legume
Engineered Varieties
Modern biotechnology has developed enhanced versions of:
Agricultural Impact
