Variations in UV radiation in Chile
(1995)
The first observation of UV global radiation in Chile with a portable multichannel radiometer are reported. Four UV wavelengths are included: 305, 320, 340 and 380 nm. Observation latitudes spanning from 18° to 53 °S allow ...
Ratios of UV, PAR and NIR components to global solar radiation measured at Botucatu site in Brazil
(Pergamon-Elsevier B.V. Ltd, 2011-01-01)
The relationships between the four radiant fluxes are analyzed based on a 4 year data archive of hourly and daily global ultraviolet (I(UV)), photosynthetically active-PAR (I(PAR)), near infrared (I(NIR)) and broadband ...

Ultraviolet-B and water stress effects on growth, gas exchange and oxidative stress in sunflower plants
(Springer, 2008-07-01)
The effects and interaction of drought and UV-B radiation were studied in sunflower plants (Helianthus annuus L. var. Catissol-01), growing in a greenhouse under natural photoperiod conditions. The plants received approximately ...
