Compared sensitivity of seedlings from 3 woody species (Quercus robur L, Quercus rubra L and Fagus silvatica L) to water-logging and associated root hypoxia: effects on water relations and photosynthesis

To investigate whether the hydraulic changes imposed by the root herbivore influence the systemic resistance, we sub- jected maize seedlings to different water regimes and mea-
