e0“corn ( Zea mays L.) plants were grown at soil water potentials of −035 and −2.50 bars for 6 days”
e1“When the soil water potential was decreased from −035 to −2.50 bars, leaf elongation rates decreased 44% and soluble carbohydrate concentrations increased 42%, while rates of total dry matter accumulation and transpiration decreased 26 and 24%, respectively”

- Intervention effect Decreasing soil water potential from −035 to −2.50 bars decreased leaf elongation rate by 44%.
- Intervention effect Decreasing soil water potential decreased total dry matter accumulation by 26% in corn seedlings.
- Intervention effect Decreasing soil water potential decreased transpiration by 24% in corn seedlings.
- Association Soluble carbohydrate concentration was inversely related to leaf elongation rate and total dry matter accumulation in corn seedlings.
- Mechanism Corn seedlings maintain a positive carbon balance in the leaves partly as soluble carbohydrates during mild water stress.
- Observation Sensitivity of leaf elongation rate to mild water stress is an important growth-determining factor in corn.
