Abstract
Kharkov winter wheat seeds soaked for 24 hours in 100 p.p.m. gibberellin solution, or in water, were sown on six weekly dates from August 21, to September 25, in the field, in black loam soil, at Edmonton. The chemical stimulated the shoot-growth that occurred before freeze-up but reduced the vigour of subsequent spring-growth, significantly reduced the numbers of survivors from the later seedings, retarded heading, and in most cases significantly reduced the forage yield. The adverse effects of the gibberellin treatments were intensified by the delays in seeding time, which also retarded the development of the untreated wheat.
