Other claims from this paper (12)
- Intervention effect Salt stress reduced visual quality, growth rate and biomass.
- Observation Salt stress caused leaf burn and necrosis.
- Association Visual scores of both species decreased with increasing salinity.
- Observation At 7.5 dS⋅m −1 P. barbatus averaged a visual score of 1.7.
- Observation At 7.5 dS⋅m −1 P. strictus averaged a visual score of 2.5.
- Observation Both species had severe foliar damage or died at 10.0 dS⋅m −1.
- Intervention effect P. strictus leaf area fell 92% at 10.0 dS⋅m −1 versus control.
- Intervention effect P. barbatus shoot dry weight fell 7% to 18%, without statistical significance.
- Association P. strictus shoot dry weight fell 13% to 31% as salinity increased.
- Association Photosynthetic rate, stomatal conductance and transpiration decreased with salinity.
- Association Sodium and chloride contents rose with salinity in both species.
- Observation Authors judged both species sensitive at 7.5 and 10.0 dS⋅m −1.
