Summary

The growth and development of the spring wheat varieties Kolibri, Sirius and TB 435 ranging in height from relatively tall to semi-dwarf were compared when sown at 50, 200 and 800 plants m−2, with and without a spray application of CCC at the six-leaf stage. Growth analysis measurements were made throughout the season. Yield and yield components were determined at final harvest.

A number of varieties x density and variety x CCC interactions were found which support the hypothesis that genotypic variation and environmentally induced differences in GA metabolism affect the agronomic performance of the crop.
