Reduced ascorbate pool and its maintenance are important determinants of O damage to net photosynthetic rate in Fagus crenata under elevated CO and soil N supply.

Many studies have reported modification in the degree of O damage to photosynthesis by elevated CO and soil N supply. However, the mechanism underlying the modification is unclear. To clarify the important determinants in the degree of O damage to net photosynthetic rate (A) in the leaves of Fagus crenata (Siebold's beech) under elevated CO and with different soil N supply, F.

Effects of elevated ozone and carbon dioxide on the dynamic photosynthesis of Fagus crenata seedlings under variable light conditions.

Ozone (O) is an air pollutant that is toxic to trees. O reduces steady-state net photosynthetic rate (A), and the adverse effects of O are mitigated under elevated CO condition. However, the combined effects of O and elevated CO on dynamic photosynthesis under variable light conditions have not yet been clarified.

Growth and photosynthetic responses to ozone of Siebold's beech seedlings grown under elevated CO and soil nitrogen supply.

Ozone (O) is a phytotoxic air pollutant, the adverse effects of which on growth and photosynthesis are modified by other environmental factors. In this study, we examined the combined effects of O, elevated CO, and soil nitrogen supply on Siebold's beech seedlings. Seedlings were grown under combinations of two levels of O (low and two times ambient O concentration), two levels of CO (ambient and 700 ppm), and three levels of soil nitrogen supply (0, 50, and 100 kg N ha year) during two growing seasons (2019 and 2020), with leaf photosynthetic traits being determined during the second season.

Compressive propagation with coherence.

In this Letter, we present wave propagation models of spatially partially coherent (or spatially incoherent) light to compress the computational load of forward and back propagations in inverse problems. In our model, partially coherent light is approximated as a set of random or plane wavefronts passing through spatial bandpass filters, which corresponds to an illumination pupil, and each wave coherently propagates onto a sensor plane through object space. We show that our models reduce the number of coherent propagations in inverse problems, which are essential in optical control and sensing, such as computer-generated holography (CGH) and quantitative phase imaging.
