Leaf expansion is reduced in mild water stress. Early detection of water stress can be accomplished with digital images taken at daily or hourly intervals.
- Digital cameras can be used to determine leaf expansion and relative growth rate.
- Digital cameras can also be used to detect early symptoms of water stress.
