Figure 1.
Spider plot of selected fluorescence parameters characterising the changes in PSII of green (A) and red (B) kale microgreens cultivated under different spectral compositions of light. All values are shown as per cent of the control (W light) (W light = 100). The parameters are divided into the following groups: energy fluxes, quantum yields and efficiencies, specific energy fluxes (calculated per single RC), and generalised parameters of PSII functional activity, i.e., performance indexes. (KGW—green kale under white light, KGB—green kale under white + blue light, KGR—green kale under white + red light, the same for KR—red kale). The presented data are mean values based on 20 replicates.
