Studies on weather fleck on tobacco leaves. 12. Interactions of environmental factors and the ozone sensitivity of tobacco plants



Studies on weather fleck on tobacco leaves. 12. Interactions of environmental factors and the ozone sensitivity of tobacco plants



Bulletin of the Okayama Tobacco Experiment Station (35): 3-21



Visible flecks were induced by 30 pphm h O3 in H-Z and by 20 pphm h in Bel W3, but the relationship between O3 level and injury was non-linear. Shorter exposures with higher O3 levels were more injurious than larger exposures. Plants grown at 23 deg C were more sensitive than those grown at 13 deg and night temperature had a greater effect than day temperature. High temperatures after treatment increased the rate of development of injury symptoms.
