Other claims from this paper (6)
- Observation Stomatal frequency increased across successive leaves to the third or fourth leaf, then decreased up to the highest leaf.
- Observation Total stomata per leaf varied among successive leaves of a shoot and among plants grown under different light intensities.
- Intervention effect Lower light intensities changed the character of stomatal frequency gradients.
- Association Leaves with higher stomatal frequency showed the largest response to light intensity.
- Association Gradients within individual leaves depended on leaf insertion.
- Intervention effect Light intensity influenced the shape and slope of leaf gradients.
