The light spectrum composition in white light (WL) and white light + farred (WL+FR) light conditions using in this chapter. The figure shows two light spectra, photosynthetic photon flux density (PPFD) plotted against wavelength. The black line in the light spectrum represents the white light (WL) conditions and the red line represents the white light + far red (WL+FR) conditions. 0 100 200 300 400 500 600 700 800 900 380 389 398 407 416 425 434 443 452 461 470 479 488 497 506 515 524 533 542 551 560 569 578 587 596 605 614 623 632 641 650 659 668 677 686 695 704 713 722 731 740 749 758 767 776 Internsity(umol/m2 *sec) Wavelength (nm) WL WL+FR Figure 2.21. The light spectrum composition in white light and white light + far-red light conditions using in epidermis imprint and xylem quantification experiments.
