43,725 | Influence of ozone air pollution on plant-herbivore interactions Part I: Biochemical changes in ornamental milkweed (Asclepias curassavica L; Asclepiadaceae) induced by ozone | Bolsinger, M; Lier, ME; Lansky, DM; Hughes, PR | 1,991 | A series of fumigation experiments was conducted with bloodflower (Asclepias curassavica L.) in continuous-flow stirred tank reactors (CSTRs) to elucidate the effects of ozone on foliar concentrations of several primary and secondary plant metabolites relevant to herbivores. Plants 8 weeks of age were subjected to diff... | 0 |
43,812 | Photosynthetic and stomatal conductance responses of Norway spruce and beech to ozone, acid mist and frost - a conceptual model | Eamus, D; Murray, M | 1,991 | Two-year-old beech and Norway spruce seedlings were exposed to a combination of ozone and acid mist treatments in open-top chambers in Scotland during the months of July through to September 1988. Replicate pairs of chambers received charcoal-filtered air (control), ozone-enriched air (140 nl ozone litre(-1)) or 140 nl... | 0 |

The quotient of water uptake to water loss never falls below 0.9 in healthy material because of the control capacity of the st... | 0 |
