| Resumo | An experiment was conducted during the spring of 1991 at USDA Beltsville Agricultural Research Center to evaluate the combined effect of carbon dioxide (CO2)and ozone (O3)on remotely sensed multispectral canopy reflectante and grain yields in winter wheat (Triticum awstivum L.). Plants weregrown full-season (after dormancy to harvest)in the field in open-top chambers supplied with charcoal-filtered air (CF)or CF + 40 nl/1 O3 concentration (7 h/day, 5 days/week)having co2 concentration of ambient (3501/1)or +150 1/1 co2 (12 h2/day). The resultant seasonal 7 h O3 concentration was 19nl/l and 79 nl/lO3, for low and high O3 treatments, respectivel. Multispectral canopy reflectante was measures weekly from the early vegetative stages until maturation. The normakized difference vegation index (ND), which was used to estimate the fraction of absorbed photosynthtically active radiation (FAPAR)and absorbed PAR (APAR). Total final biomass and grain yield was obtained after harvest at physiological maturity. Tests of main effect of O3 on ND was significant from the third week of treatment until maturation. Main effect of CO2 on ND was not significant for all measurement dates. However, main effects of CO2 and O3 were significant for both biomass and grain yield. Accumulated APAR over the growing seasom was significantly lower the high-O3 treatments. Plants grown under CO2 enriched air had significantly higher conversion efficiency (E)of APAR into above gorund dry biomass tham plants grown under ambient CO2 air. Conversion efficiency was significantly lower for the O3 treatment with ambient CO2 air. High-O3 treatments had about 15 less grain weight than low-O3 treatments. Enriched CO2 treadtments had about 25 more grain weight than ambient CO2 treatments. Regression analysis showed that ND was responsible for up to 76 the grain yyield variation for winter wheat growing under the different air qualities. |
