Supplemental LED inter-lighting compensates for a shortage of light for plant growth and yield under the lack of sunshine
Fig 3
Total chlorophyll contents of single-truss tomato leaves measured in three canopy layers in plants grown under shading during 0%, 40% and 60% of days, with or without LED inter-lighting.
Data are means ± SEM (n = 15). Values marked with the same letter are not significantly different for the same leaf number in different treatments (Tukey’s HSD at P < 0.05).
