Abstract
2-CHLOROETHYLTRIMETHYLAMMONIUM chloride (CCC) shortens wheat straw and is used to lessen losses caused by lodging, but there is good evidence that it sometimes also increases the yield of wheat in other ways. For example, Humphries, Welbank arid Witts1 reported an increase of 5 per cent in the grain yield of ‘Phoebus’ spring wheat after spraying with either 2.5 lb. or 5 lb./acre of CCC at the five leaf stage, although plants in the untreated plots did not lodge. They tentatively attributed the increase to the better penetration of light through the crop enabling more ear-bearing shoots to survive.
