Other claims from this paper (11)

Intervention effect Removing half the barley florets increased dry weight of the rest of the plant.
Observation The dry weight effect of floret removal was greatest 17 days after ear emergence.
Observation Later, shoot weight differences between 24 and 12 florets per ear disappeared.
