Influence of foliar ozone injury on root development and root surface fungi of pinto bean plants

Chronic exposure of Pinto bean plants to levels of ozone sufficient to cause foliar injury adversely affected shoot and root growth and vigour and enhanced senescence. These effects were reflected in quantitative rather than qualitative differences in the successional root surface fungi. More fungal...

Description
Summary:Chronic exposure of Pinto bean plants to levels of ozone sufficient to cause foliar injury adversely affected shoot and root growth and vigour and enhanced senescence. These effects were reflected in quantitative rather than qualitative differences in the successional root surface fungi. More fungal colonies were consistently isolated from the roots and hypocotyls of plants exposed to ozone than from those grown in charcoal-filtered air. Roots and hypocotyls of plants exposed and not exposed to ozone were colonised by the same fungi and each had the same general mycoflora at each sampling period. Rhizobium nodules were found on the roots of plants grown in charcoal-filtered air, but were not found on the roots of plants grown in the ozone chamber.
