Document Summary
Effects of light stress on photosynthesis in barley, According to data analysis from the food and agriculture organization of the united. Nations, (1961-2017) the total agricultural land has shown a decreasing trend worldwide since 2000. The primary aim of this study was to examine the effects of acute increasing irradiance on photosynthesis for low light acclimated barley. Barley leaves acclimated under the low light condition for one week would show a lower photosynthetic rate compared with leaves acclimated under full light condition after exposing to acute higher irradiance. The comparison was made under equal artificial light conditions for both groups and the photosynthetic rate was represented in terms of net carbon flux rate. Photosynthesis rate of hordeum vulgare acclimated to high (9. 32 2. 39 mol co2/m2 s, n=52; light grey) and low (7. 37 0. 81 mol co2/m2 s,n=54; dark grey) irradiance conditions.
