Figure 7

The effect of Red, Blue, Fluorescent light, and combined LEDs of red and blue light [RB (1:1, 8:2, and 2:8) respectively] on leaf chlorophyll-a, chlorophyll-b, carotenoids, Fv/Fm ratio, leaf anthocyanin, and total UV-absorbing compounds content in Digitalis purpurea L., under a closed type plant factory. The data represents mean ± standard error. Data columns with different alphabets are significantly different according to Duncan’s multiple range test at p < 0.05.
