WebNov 17, 2010 · Photoinhibition is a term that is often used to refer to a light-induced decrease in ΦCO 2 and/or A max. However, some flexible photoprotective processes will also unavoidably reduce ΦCO 2 and F v / F m, resulting in symptoms of moderate photoinhibition ( Fig. 1B) that are usually transient. WebPhotoinhibition is light-induced reduction in the photosynthetic capacity of a plant, alga, or cyanobacterium. Photosystem II (PSII) is more sensitive to light than the rest of the …

WebNov 1, 2003 · An interaction of the costs of these compounds against benefits of nitrogen levels may explain patterns in intake. We suggest that, while environmentally induced levels of carbon-based plant secondary metabolites have consequences for herbivory, photoinhibition may drive the adjustment of levels of leaf phenolics in response to … Webcost, and, if so, whether this cost constitutes a sig-nificant proportion of daily photosynthetic energy acquisition. Photoinhibition, whether dynamic or chronic, may comprise an energetic cost by reducing the maximum rate of photosynthesis (MAXP ) at supra-saturating light levels (e.g. Platt et al. 1980). Alternatively, costs may four hands bibiana dining table

WebPhotoinhibition of Photosystem II (PSII) is the light-induced loss of oxygen evolution and electron-transport activity of PSII. In this chapter, the word “photoinhibition” is used in its traditional meaning (Kok, 1956; Samuelsson et al., 1985; Greer et al., 1986; Tyystjärvi and Aro, 1996) to describe irreversible inhibition that does not ...
