Observation Jennifer had dry weight per unit length of 2·34 mg/mm, among the strongest cultivars.
Observation Pipkin had dry weight per unit length of 1·75 mg/mm, the lowest among the cultivars.
Intervention effect Nitrogen application increased plant height.

Intervention effect Nitrogen application decreased dry weight per unit length of stem.
Intervention effect The growth regulator treatments reduced plant height.
Intervention effect Dry weight per unit length of stem was similar in growth-regulator-treated and untreated plots.
Recommendation Dry weight per unit length has potential as an objective indicator of straw strength and could be used in cultivar evaluation in the absence of damage in field trials.
