Fig. 7From: A whole canopy gas exchange system for the targeted manipulation of grapevine source-sink relations using sub-ambient CO2Average diurnal canopy photosynthesis rates for ambient sub-ambient CO2 supplied chambers (n = 3) for 10 days from December 26, 2013, and 4 days following the return of the sub-ambient chambers to ambient air supply on January 5. Measurement points shown in relation to Australian Eastern Daylight Time (AEDT). The corresponding supply CO2 difference for sub-ambient to ambient in shown in Fig. 4bBack to article page
