Other claims from this paper (5)
- Observation Cells of primary bean leaves are maximally sensitive to ozone 9–10 days after germination.
- Association The stage of maximum ozone sensitivity was not correlated with changes in stomatal number or resistance on either leaf surface.
- Mechanism Bean leaf sensitivity to ozone is a function of more internal circumstances, and gas exchange was never the limiting factor.
- Association Changes in leaf resistance were not significantly altered by ozone levels that produced no visible injury.
- Intervention effect After high ozone doses, adaxial resistance decreased, apparently as a result of palisade and epidermal cell lysis.
