The effect of light spectral quality on leaf senescence and oxidative stress in wheat

We have investigated the effects of deprivation of specific wavelengths on the induction of leaf senescence and oxidative metabolism in wheat. Excised leaves of 18–20-day-old plants were incubated in plastic boxes on distilled water and exposed to light filters with different ratios of red (R = 660 nm) to far-red (FR = 730 nm) radiation (treatments red (R), R/FR = 0.84; green (G), R/FR = 0.12; or blue (B), R/FR = 0.13). Boxes with no added...
