Researchers subjected the seedlings to vernalisation to induce earlier flowering under controlled conditions.

The wheat seeds were vernalised before planting to ensure timely flowering.

The botanist observed the seedlings vernalising in the cold chamber to ensure spring flowering.

In the laboratory protocol, the technician vernalises the seedlings for two weeks before transplanting them outdoors.

To ensure uniform flowering next spring, the horticulturist decided to vernalise the seedlings in a cold room for six weeks.
