Variance in paprika plant growth during supplemental lighting application. (a) Height, (b) number of nodes, (c) number of leaves, and (d) leaf area index (LAI) increased compared with the initial values. Supplemental lighting treatments: QD-IL, QD inter-lighting; CW-IL, cool-white inter-lighting; B+R-IL, blue + red inter-lighting; CW-TL, cool-white top-lighting; Cont, without supplemental lighting. Vertical bars indicate ± SEM (n = 21). Values marked with different letters indicate significant differences according to Duncan’s multiple range test at the 5% level.
