Other claims from this paper (13)
- Observation Affected leaves commonly showed smoky spots of SO2 injury.
- Observation Some affected leaves showed small poxlike spots of sulfuric acid mist injury.
- Observation Some leaves shed rapidly without visible disease spots.
- Observation Soil acidity was greater at 10 cm than at 30 cm in the affected orchard.
- Association Soil pH was not significantly correlated with atmospheric SO2 concentration (r = -0.2).
- Observation Leaf S content was generally high in the affected orchard.
- Association Leaf S content was strongly correlated with atmospheric SO2 in July 1963, with r = +0.85.
- Association Leaf S content was strongly correlated with atmospheric SO2 in January 1964, with r = +0.79.
- Association Leaf S content increased with leaf age.
- Association The rise in leaf S content was greatest when SO2 gas flowed into the orchard.
- Association Leaf S and Ca contents were negatively correlated (r = -0.67).
- Association Leaf K and Mn content rose with leaf S content, without significant correlation.
- Association Leaf N, P and Mg contents had no relation to leaf S content.
