The Impacts of Drought Stress and Phytophthora cinnamomi Infection on Short-Term Water Relations in Two Year-Old Eucalyptus obliqua

The effects of drought stress, Phytophthora cinnamomi infection and their interaction on water relations growth were examined for 28 days two year-old potted trees Eucalyptus obliqua (L’Hér.). There significant stress plant photosynthesis, stomatal conductance, biomass accumulation, potential at turgor loss point the bulk modulus elasticity. E. was successfully infected but showed only mild symptoms. Infection with P. led to a reduction in root root-to-shoot ratio well-watered droughted plants did not impact relations. no observable cumulative effect infection. are multiple reasons why lead drought-like symptoms obliqua, including short experimental duration, delayed symptoms, resistance possible lower aggressiveness strain. Hence, our results indicate that will always immediate short-term mildly symptomatic respond very similar compared non-infected trees.
