Figure 1.

Photosynthetically active radiation (PAR) spectrum of compact fluorescence growth light within the Bio-chambers for plants involved in leaf studies (A), as well as HPS, RB LED, and RW LED from Philips Lighting Company and LSGC, respectively which were used during both greenhouse grow periods and during whole plant analysis. (B) provides the PAR spectrum of PAR 38 LED floodlights from LSGC. All light spectra were determined using a spectroradiometer (Flame Spectrometer, Ocean Optics, Dunedin, FL, USA). Spectral composition (%) of each light can be found in Supplementary Table 1.
