The paper deals with the measurement of the resonance frequencies of wheat stems with special respect to different wheat varieties. For the measurement, the dynamical method of the transverse frequency was used. Formulas were derived for the calculation of the bending toughness of stems. The t-test was used for the evaluation of the strength coefficient in bending for the samples of stems of different wheat varieties. The results can be used for the evaluation of the wheat resistance to lodging.Keywords:wheat stems; resonance frequency; strength coefficient in bending; modulus of elasticity; mechanical properties of stem
