The growth of wheat seedlings from seed treated with a .5% CCC solution was studied under greenhouse conditions. Length of coleoptile, length of culm to first leaf blade, total shoot length, and dry weight of shoots were reduced by the seed treatment. Length of longest root and dry weight of roots were not reduced appreciably after the initial week of growth. A method of applying CCC as a dust treatment to wheat seed was developed and used in field experiments. Considerable differences in varietal response for a number of agronomic characteristics were found in replicated field experiments over a 2‐year period. The stand of ‘Gaines,’ a semidwarf variety, was reduced, the stands of ‘Omar’ and ‘Golden’ were increased, and the stand of ‘Brevor’ was not affected. Yield increases were found in the three tall varieties while a reduction in yield was noted for the semidwarf variety. Straw‐grain ratio was reduced in all four varieties. Effect of CCC on lodging resistance could not be evaluated.
