overall reduction in growth but no obvious signs of visible damage ( Wellburn, 1990 ) and mainly affect the physiological metabolism of plants. Chlorophyll (Chl) is the most important plant pigment because it has a crucial role in photosynthesis ( Croft et

were observed, which were lower than the basil grown under DLIs of 28.8 and 34.6 mol·m −2 ·d −1 in a growth chamber, respectively ( Beaman et al., 2009 ). In a glasshouse condition, there was no difference in photosynthesis of ‘Genovese’ basil between

strawberry ( CDFA, 2007 ). While numerous studies provide evidence of the physiological effect of elevated CO 2 concentration on many plant species in growth chambers, research on raspberry examined physiological processes such as photosynthesis, but yield

deficiency and N re-supply on growth and quality of leaf-vegetable sweetpotato. Therefore, the objectives of this study were to 1) investigate the effect of N deficiency and subsequently N-resupply on growth, photosynthesis and related physiological processes

. Goudriaan for their excellent suggestions for adapting the sunlit leaf area index approach for hedgerow canopies. We thank J. Norman for his advice on the model and E.B. Blazey and G. Bourgeois for their assistance with photosynthesis measurements. The cost

Plant growth and development are largely affected by spectra properties of light through mediating photosynthesis and photomorphogenesis. UV radiation critically influences terrestrial plants, and many studies are now available concerning the effect

depths with three replicates. The measurement positions were adjusted with the growth of the plants ( Fig. 2 ). The temperature was measured from 5 June 2017 to 10 July 2017. Measurements of leaf photosynthesis and solar radiation transmittance. The P n

. Photosynthetic rate (Pn), g s , internal leaf CO 2 concentrations (C i ), and leaf temperature were determined on young but fully expanded leaves using a photosynthesis measurement system (LI-6400; LI-COR, Lincoln, NE). Photosynthetically active radiation ( PAR

. Contradictory results have been reported for NAR. Heraut-Bron et al. (1999) demonstrated that the R:FR did not affect photosynthesis per unit leaf area of white clover ( Trifolium repens L.). However, other reports demonstrated that low-R:FR light reduces the
