Regulation of Excited States in Photosynthesis of Higher Plants,esses i.e.: photochemistry, fluorescence and internal conversion. In a dark adapted leaf, the yield of photochemistry is high; the quantum yield of linear electron flow through the two photosystems measured in dim light is close to 0.1 μmole O. evolved per μEinstein absorbed. Therefore the quantum y

Interaction of UV Radiation with the Photosynthetic Systems,ion reaching ground level. Although many of the ozone-depleting chemicals are scheduled to be phased out in the near future, in practical terms there will be large discrepancies in the rates of phasing out among countries. Chlorofluorocarbons, with lifetimes of many decades, and nitrogen oxides (NO.

Light Signal Transduction Mediated by Phytochromes,ts of the activation of these photoreceptors are dramatically illustrated by comparing the morphologies of dark grown seedlings to those exposed to ambient light (Fig. 1). Dark-grown (etiolated) seedlings are typically white in color, have elongated stems, and lack leaves and flowers. Exposure to li

Light Penetration into the Canopy of Terrestrial Ecosystems,and is variously reflected, absorbed, and transmitted. Although these are concepts in photophysics which it should be possible to describe in simple and easily quantifiable terms, natural radiation is a complex phenomenon which varies in quantity, quality, and time. The vegetation canopy is also a c

Light Penetration and Effects on Aquatic Ecosystems,0.5% of the total water surface the major share is represented by marine systems. In these the main biomass producers are (mostly unicellular) phytoplankton organisms. However, also macroalgae — with a few exceptions — limited to coastal areas, have a large share in productivity. Almost all primary
