Other claims from this paper (7)
- Intervention effect At pH 3.0 photosynthesis fell significantly in radish and common bean.
- Intervention effect At pH 2.5 photosynthesis fell significantly in fleabane and white clover.
- Intervention effect Six species showed almost no photosynthesis decrease even at pH 2.5.
- Intervention effect Leaf respiration increased in most species compared with controls.
- Intervention effect Acid rain spraying caused little change in stomatal conductance in four measured species.
- Intervention effect At pH 2.5 chlorophyll content fell over 10% in all species except crabgrass and tall fescue.
- Association Relative chlorophyll a content and relative photosynthetic rate had a linear regression relationship.
