P. J. Temple; L. F. Benoit; R. W. Lennox; et al. Journal of Environmental Quality 1988. doi:10.2134/jeq1988.00472425001700010016x
Other claims from this paper (14)
- Intervention effect Water stress reduced seasonal yield about 10% in 1984.
- Intervention effect Water stress reduced seasonal yield 27% in 1985.
- Intervention effect Ozone significantly reduced yields in both years.
- Association Ozone and water stress interacted significantly in 1985 and combined years.
- Intervention effect In normally irrigated plots, NF × 1.3 reduced 1985 yield 14.9%.
- Intervention effect In normally irrigated plots, NH × 1.7 reduced 1985 yield 24.3%.
- Intervention effect In normally irrigated plots, NF × 2.0 reduced 1985 yield 24.9%.
- Intervention effect In water-stressed plots, NF reduced 1985 yield 5.9%.
- Intervention effect In water-stressed plots, NF × 1.3 reduced 1985 yield 7.2%.
- Intervention effect In water-stressed plots, NH × 1.7 reduced 1985 yield 13.5%.
- Intervention effect In water-stressed plots, NF × 2.0 reduced 1985 yield 18.1%.
- Observation Ozone dose-yield loss functions were homogeneous between years.
- Intervention effect Ozone significantly reduced crown weights.
- Mechanism The authors suggest continued ozone exposure could shorten productive stand life.
