plant photosynthesis and carbon use efficiency in wax begonia. Our regression analysis indicates that net photosynthetic rate of cyclamen was highest when grown under DLI of ≈17 mol·m −2 ·d −1 . Moe (1994) divided the response of herbaceous ornamental

endogenous GA levels where leaf photosynthetic rates were lower but whole-plant photosynthesis was higher. We found no significant differences in instantaneous leaf photosynthetic rates among any of the treatments in our study; however, we did not measure

rationale that lower-canopy leaves, which normally would receive relatively little light and therefore contribute very little to whole-plant photosynthesis and biomass production, may be of greater photosynthetic value when growing with SCL. Future studies

responses to irradiance and CO 2 and whether some varieties were more suited to supplemental, or reduced, irradiance and CO 2 levels. We acknowledge that translating instantaneous P n measurements on a per-unit-area basis to whole-plant photosynthesis

expansion under shade signals such as a low ratio of R to FR radiation can increase radiation capture, thereby promoting whole-plant photosynthesis ( Park and Runkle, 2017 ). Many shade-induced genes upregulated by FR radiation can also be activated by G

reduction of a certain percentage of light is often accompanied by an approximately equal reduction in whole plant photosynthesis ( Frantz and Bugbee, 2005 ; Nemali and van Iersel, 2004 ). Shading [or a reduction in daily light integral (DLI)] also leads to

because such measurements do not take into account the total leaf area of plants. They found that high nutrient concentrations had no effect on photosynthesis per unit leaf area, but inhibited leaf elongation and thus whole-plant photosynthesis and dry
