Other claims from this paper (9)
- Association Relative leaf surface expansion increased with temperature up to 24o, then was lower at 30o.
- Intervention effect Higher radiation slightly increased relative leaf surface expansion at lower temperatures only.
- Association Leaves unfolded from terminal buds more rapidly as temperature rose across the range.
- Association Individual leaf expansion was greatest at 240 and lower at both cooler and warmer temperatures.
- Observation Temperature differences in individual leaf expansion increased from cotyledon to leaf 1 to leaf 2.
- Intervention effect Higher radiation increased leaf production and unfolding.
- Intervention effect Higher radiation did not change expansion of individual leaves.
- Mechanism The authors proposed that unfolding from the terminal bud sets potential leaf surface expansion.
- Mechanism The authors proposed that reduced cell division lowers leaf expansion and leaf size when mineral demand exceeds supply.
