Growth and productivity of several crop cultivars were related to physiological and biochemical parameters. In laboratory studies seed germination was not sensitive to SO/sub 2/ and ozone but root growth was sensitive. SO/sub 2/ inhibited pollen tube growth; ozone had no effect on pollen viability. Differential SO/sub 2/ sensitivity in corn cultivars was related to cellular uptake and detoxification. SO/sub 2/ induced ethylene production in a sensitive corn cultivar without visible injury. In bean cultivars sensitivity to ozone was correlated with stomatal uptake. Ozone decreased plant growth and pod yield, and lowered leaf water potential prior to bloom.
