Other claims from this paper (12)
- Observation The barley first leaf was fully expanded by day 8.
- Observation Maximal photosynthesis rates occurred about one day after day 8.
- Mechanism Barley seedling growth up to day 8 resulted from redistribution of seed reserves.
- Mechanism Once seed reserves were exhausted, seedling growth depended on the first leaf.
- Intervention effect Shading the first leaf reduced barley seedling growth to very low levels after seed reserves were exhausted.
- Observation The second leaf began rapidly expanding after day 10.
- Observation The second leaf contributed to growth by day 14.
- Observation The first leaf contribution to barley growth began declining after day 12.
- Intervention effect Shade greatly reduced photosynthesis in treated leaves.
- Intervention effect Shade applied for at least two days from day 6 reduced peak carbon fixation on days 9 and 10 by up to 35 per cent.
- Mechanism First-leaf dry weight development depended on photosynthesis in the developing leaf.
- Mechanism First-leaf photosynthetic capacity development depended on photosynthesis in the developing leaf.
