Abstract
This study examines the effect of calcium (Ca) supply on infection of narrow-leafed lupins (Lupinus angustifolius) by Diaporthe toxica the c ause of lupinosis in animals. Susceptible cv. Yandee and resistant bre eding lines CE2:435 and 75A:258 were grown in solution culture at vary ing levels of Ca supply. Epidermal Ca concentration increased with inc reased Ca supply in both resistant and susceptible narrow-leafed lupin s. There was an inverse relationship between the concentration of epid ermal Ca and the frequency of infection by the fungus.
