Growth and yield characteristics of 'Waldmann's Green' leaf lettuce under different photon fluxes from metal halide or incandescent + fluorescent radiation
{{output}}
'Waldmann's Green' leaf lettuce (Lactuca sativa L.) was grown either under 84% irradiance from incandescent (In) + 16% from fluorescence (Fl) lamps, or 100% from metal halide (MH) lamps, both at 392 micromoles s-1 m-2 of photosynthetically active radiation (40... ...
