Supplemental LED inter-lighting compensates for a shortage of light for plant growth and yield under the lack of sunshine
Fig 7
Relation between yield and daily light integral (DLI).
Open circle: plants grown under shading during 0%, 40% and 60% of days, Filled triangle: plants grown under shading during 40% of days with supplemental LED inter-lighting, filled square: plants grown under shading during 60% of days with supplemental LED inter-lighting. The regression line among plants grown under shading during 0%, 40% and 60% of days is shown (y = 0.1869x + 1.0605, R2 = 0.97).
