摘要: The increasing concentration of carbon dioxide in the atmosphere ([CO,]) has several direct effects on plants and these may be different for C, plants. Our objective was to measure hourly daily whole-plant transpiration rates from plant grain sorghum (Sorghum bicolor (L.) Moench) soybean (Glycine max Merr.) grown under ambient (359 pmolC0, mol-’ dry atmospheric air) elevated (705 ymolmol- ‘> [CO,] values. Transpiration measurements were made 22 days August 1994 at Auburn, Alabama, USA, using stem flow gauges growing open top chambers, n = 8 each species. Leaf area averaged slightly more than 0.1 m* per about 0.2 soybean. Averages (15 min daily) transpiration, unit leaf area, consistently greater both Average significantly smaller (P 0.05) all but 2 9 sorghum. 1 128gm-2 day-’ 772gm-* an [CO,], respectively. Corresponding averages 731 gm-* 416gm-* day ‘. reduction These results support previous studies showing that will reduced if continues increase, although
