5 Questions
Explain the impact of water stress on crop yield and market sales.
Water stress can lead to significant reductions in crop yield, ranging from 13% to 94% depending on intensity and duration. Fruit yield is predominantly determined by water content, impacting market sales.
How do rare earth elements (REEs) in soil affect agriculture, and what is the current understanding of their ecological effects on plants?
Soils contaminated with rare earth elements (REEs) can damage agriculture, and their ecological effects and potential risks to plants are not well understood.
What are the potential effects of nano terbium (Tb) applications on duckweed, and how do low concentrations of Tb impact nutrient content in duckweed?
Nano terbium (Tb) applications at appropriate concentrations can enhance the antioxidant system, protect biochemical reactions of photosystems, and improve hormonal regulation in duckweed. Low concentrations of Tb increase nitrogen, phosphate, potassium, calcium, magnesium, manganese, and iron content in duckweed.
How does ABA biosynthesis and accumulation in plant tissues respond to abiotic stress conditions?
ABA biosynthesis and accumulation in plant tissues increase under abiotic stress conditions, triggering stress response at the cellular level.
What is the potential of Tb at appropriate concentrations in conferring tolerance in duckweed, and how does Tb toxicity affect photosystem II?
Tb at appropriate concentrations has the potential to confer tolerance in duckweed by supporting the antioxidant system, protecting photosystem reactions, and improving hormonal regulation. Tb toxicity adversely affects chlorophyll fluorescence and the active reaction center of photosystem II.
Study Notes
Phytohormones and Abiotic Stress Management
- Abiotic stress in plants is managed by organic molecules that form complex signaling cascades, impacting growth, development, and nutrient allocation.
- Water stress can lead to significant reductions in crop yield, ranging from 13% to 94% depending on intensity and duration.
- Water is crucial for maintaining normal physiological activities and membrane transport processes in plants.
- Fruit yield is predominantly determined by water content, impacting market sales.
- Climate change-induced environmental stresses can reduce yield potential and lead to shifts in cultivation areas for fruit crops.
