Abstract
THE continuous exposure of barley plants to short photoperiods leads to marked increases in the numbers of primordia and grains per ear1–4. But little is known of the effects of brief exposures to short days and here we describe the distinctive effects of such treatments given at different stages of ear development, on the fertility of the florets of ears of barley.
