Radiation dimming induced modifications in radiation utilization of wheat (Triticumaestivum) crop

open access: yesJournal of Agrometeorology, 2020
Global dimming has many environmental and climatic implications. India has also experienced a steady and continuous radiation dimming since 1960s due to increasing load of dust and aerosol in the atmosphere.

Radiation use efficiency increases when the diffuse component of incident radiation is enhanced under shade [PDF]

open access: yes, 1998
Theoretical analyses have shown the radiation use efficiency of maize, soybean, and peanut to increase with a decrease in the level of incident radiation and an increase in the proportion of diffuse radiation. This study compared the growth and radiation

Avenues for genetic modification of radiation use efficiency in wheat [PDF]

open access: yesJournal of Experimental Botany, 2000
Radiation use efficiency (RUE) of a crop is a function of several interacting physiological phenomena, each of which can be tackled independently from the point of view of genetic improvement. Although wheat breeding has not raised RUE substantially, theoretical calculations suggest room for improvement.

Intercepted Photosynthetically Active Radiation (PAR) and Spatial and Temporal Distribution of Transmitted PAR under High-Density and Super High-Density Olive Orchards

open access: yesAgriculture, 2021
We quantified the photosynthetically active radiation (PAR) interception in a high-density (HD) and a super high-density (SHD) or hedgerow olive system, by measuring the PAR transmitted under the canopy along transects at increasing distance from the ...

Diurnal and Seasonal Variations of Photosynthetic Energy Conversion Efficiency of Field Grown Wheat

open access: yesFrontiers in Plant Science, 2022
Improving canopy photosynthetic light use efficiency and energy conversion efficiency (εc) is a major option to increase crop yield potential. However, so far, the diurnal and seasonal variations of canopy light use efficiency (LUE) and εc are largely ...

Productivity and radiation use efficiency of tea grown under different shade trees in the plain land of West Bengal

open access: yesJournal of Agrometeorology, 2008
Tea is grown under shade trees at higher elevation to attain better quality and higher productivity of the leaf. Hence, a field study was carried out to study the influence the shade trees on productivity and radiation use efficiency of the tea, when ...

Photofrin II as an efficient radiosensitizing agent in an experimental tumor [PDF]

open access: yes, 2001
Background and Objective: The use of ionizing irradiation as radiation therapy (RT) for tumor treatment represents a well-established method. The use of photodynamic therapy (PDT), especially with Photofrin II, for tumor treatment is also known. Chemical
