Energy dissipation in C3 plants under drought

摘要: A general quantification of the relative contribution different light energy dissipation processes to total under drought conditions is lacking. Here we compare six studies, including enough data for such a quantification, build up pattern importance several mechanisms in response C3 plants. Such apparently emerges independently specific acclimation drought, but largely dependent on CO2 availability chloroplasts, which may be regulated by adjustments stomatal and mesophyll conductances. Under irrigation saturating light, more than 50% absorbed thermally dissipated, while photosynthesis dissipates 20-30% photorespiration 10-20%. mild decreases, that increases compensatory manner. During moderate severe both thermal 70-90% absorbed. The other processes, like Mehler reaction, shown very low drought. Therefore, plants subjected degrees 90% leaves dissipated sum dissipation, photosynthesis.
