Other claims from this paper (14)
- Observation Leaf rolling fluctuated diurnally during drying.
- Observation Stressed plants rolled partially in the morning and completely at noon.
- Observation Stressed plants showed complete rolling at noon.
- Observation Watered leaves remained within rolling scores 1 to 2 over 20 days.
- Association Leaf water potential tracked leaf rolling.
- Observation Leaf blades had smooth and ridged surfaces on opposite sides of the midrib.
- Observation The ridged portion often rolled before the smooth portion.
- Association The ridged portion had 0.48 MPa lower water potential than the smooth portion at complete rolling.
- Association The apical half had 0.41 MPa lower water potential than the basal half.
- Observation Leaf rolling included acropetal helical and non-helical forms and non-acropetal forms.
- Association Etiolated leaves rolled 14 min quicker than green leaves.
- Intervention effect Darkness delayed complete rolling of green leaves by 32 min.
- Intervention effect Manual rolling reduced transpiration by 52%, which returned after unrolling.
- Intervention effect Spontaneously rolled excised leaves saved 87% water, against 68% when rolling was prevented.
