Experiment Description:<\/strong><\/span><\/td>\nPhotosynthesis and gas exchange traits depend strongly on a combination of morphological, biochemical, and physiological properties. This experiment aims to investigate changes in gas exchange, photosynthesis and stomatal morphology and their interplay in response to increased levels of CO2<\/sub>. Five common crop species were grown in controlled climate chambers at ambient (400 ppm) and elevated (1000 ppm) CO2 levels. <\/span><\/td>\n<\/tr>\n

The experiment was conducted between September \u2013 November 2022. The climate chambers at the UWA were used with a 12h\/12h photoperiod, with temperatures set to 30\/20 \u02daC (day\/night). One litre pots with standard potting mix were used for all plants and slow release fertilizer was added. Ambient CO2<\/sub> room was at 400 ppm, elevated CO2<\/sub> room at 1000 ppm. Species included: soybean (Glycine max<\/em>), borlotti bean (Phaseolus vulgaris<\/em>), maize (Zea mays<\/em>) wheat (Triticum aestivum<\/em>), and buckwheat (Fagopyrum esculentum<\/em>).<\/span><\/td>\nAll data available on request (unpublished yet).<\/span><\/p>\n

CSV\/excel files.<\/span><\/td>\n

Pot size limited to 1 liter. Leaf age influences photosynthesis traits. Plants were flowering at harvest.\u00a0<\/span><\/p>\n

13C samples were influenced by the atmospheric value \u2013 air was sampled but comparisons between rooms may not be appropriate.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
