Abstract The changes of hydroxyproline (Hyp) content in cell wall after inoculation with Corynebacterium michiganense pv. insidiosum or Verticillium albo‐atrum in 8 cultivars of alfalfa (Medicago sativa) were studied. In our experiments cultivars ‘Trek’ and ‘Vernal’– resistant, ‘Du Puits’ and ‘Vertus’– susceptible to C. michiganense; ‘Vela’ and ‘Maris Kabul’– resistant to V. albo‐atrum , ‘Sabilt’ and ‘Lahontan’– susceptible to V. albo‐atrum were used. In resistant plants inoculated with C. michiganense none or a small increase of Hyp content in comparison with control plants was registered. On the other hand, inoculated susceptible plants showed markedly increase of Hyp content in comparison with the control plants. The differences in Hyp content between control and inoculated resistant and susceptible plants with V. albo‐atrum were not markedly expressed in comparison with the alfalfa – C. michiganense pair. The changes had similar tendency both in C. michiganense and V. albo‐atrum. – alfalfa pairs.
