Abstract
Summary The effects of differences in daylength and temperature, before ear initiation, on subsequent emergence in perennial ryegrass selections were studied in the glasshouse. When no artificial light or heat was used, prolific and uniform emergence was observed. Of seven other combinations compared, uniform but much earlier emergence was obtained from only that treatment where the natural sequence of events, cold short days followed by long warm days, was accelerated. A number of interactions occurred between the other treatments and the selections used.
