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.
Intervention effect Shade greatly reduced photosynthesis in treated leaves.
Intervention effect Shade affected the development of photosynthetic capacity.
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.
