Effect of UV-B radiation on the photoprotective and antioxidant response in Vaccinium corymbosum L.: An approach to the UV-B resistance mechanisms.
(2017)
Despite the Montreal protocol success and the eventual recovery of the ozone layer over Antarctica, there are still concerns about increased levels of ultraviolet-B (UV-B) radiation in the Southern Hemisphere. It is expected ...

Programa de intervención sobre conocimiento del Radiómetro UV como medida preventiva del riesgo de la radiación UV en estudiantes del nivel secundario del Colegio Adventista del Titicaca, Juliaca – Perú, 2019
(Universidad Peruana UniónPE, 2019-12-02)
La radiación solar ultravioleta es muy nocivo para el ser humano y la exposición prolongada puede generar cáncer en la piel, cataratas, envejecimiento prematuro por lo cual el objetivo de la presente investigación fue ...
“variaciones estacionales de índice y dosis ultravioleta (uv) en la microestación meteorológica unt durante los años 2011-2012”
(Universidad Nacional de Trujillo, 2013)
Ultraviolet radiation is a type of non-visible radiation in the solar spectrum, its wave length is short and has great power; measurements of UV radiation indicate us the degree of intensity with which reach the Earth´s ...
Functional acclimation to solar UV-B radiation in Gunnera magellanica, a native plant species of southernmost Patagonia
(Wiley Blackwell Publishing, Inc, 2003-12)
The ecosystems of Tierra del Fuego (in southern Patagonia, Argentina) are seasonally exposed to elevated levels of ultraviolet-B radiation (UV-B: 280-315 nm), due to the passage of the 'ozone hole' over this region. In the ...

Sensitivity of yellow passion fruit plants to ultraviolet-B radiation
(2012)
The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted ...
High altitude solar UV-B and abscisic acid application increase grape berry antioxidant capacity
(Amer Soc Enology Viticulture, 2015-02)
It has been proposed that ultraviolet-B (UV-B) radiation activates grapevines antioxidant defense system and abscisic acid (ABA) acts downstream in the signaling pathway. Effects of solar UV-B perceived by high altitude ...
Modeling hourly and daily fractions of UV, PAR and NIR to global solar radiation under various sky conditions at Botucatu, Brazil
(Elsevier B.V., 2009-03-01)
In this analysis, using available hourly and daily radiometric data performed at Botucatu, Brazil, several empirical models relating ultraviolet (UV), photosynthetically active (PAR) and near infrared (NIR) solar global ...
