Title
Effect of salinity on pythium damping‐off of cucumber and on the tolerance of Pythium aphanidermatum
A. M. Al‐Sadi; R. S. Al‐Masoudi; N. Al‐Habsi; et al. Plant Pathology 2009. doi:10.1111/j.1365-3059.2009.02176.x
Other claims from this paper (10)
- Intervention effect Increasing irrigation-water salinity to 5 dS m -1 significantly increased mortality of cucumber seedlings inoculated with P. aphanidermatum.
- Intervention effect Increasing irrigation-water salinity reduced dry weight of non-inoculated cucumber seedlings.
- Intervention effect In vitro, growth of P. aphanidermatum, P. spinosum and P. splendens isolates was stimulated or unaffected at salinity levels stressful for cucumber.
- Observation The NaCl concentration required to reduce growth of P. aphanidermatum isolates by 50% varied from 23 to 62 dS m -1, averaging 46 dS m -1.
- Intervention effect No oospores were produced above 20 dS m -1 salinity.
- Association Tolerance to salinity showed no relationship with geographical origin or genetic data of P. aphanidermatum isolates.
- Association Isolates from greenhouses without salinity problems were as tolerant to salinity as isolates from salinity-affected greenhouses.
- Association The data suggest a lack of evidence for ecological adaptation of P. aphanidermatum to salinity in Oman.
- Observation Significant differences in salinity tolerance were found among 47 P. aphanidermatum isolates from different greenhouses.
- Mechanism Increased mortality at higher salinity may imply a synergistic interaction between salinity stress and salinity-tolerant Pythium species.
