Despite the Montreal protocol 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. UV-B induces physiological, biochemical and morphological stress responses in plants, which are...
The effects of increased doses of UV-B radiation on anatomical, biochemical and molecular features of leaves of two highbush blueberry (Vaccinium colymbosum L cv. Brigitta and Bluegold) genotypes were investigated. Plants were grown in a solid substrate and exposed to 0, 0.07, 0.12 and 0.19 Wm(-2...
We studied physiological traits and Mn transporter genes expression in ryegrass genotypes (One -50, Banquet -II, Halo-AR1 and Nui) under increasing Mn (2.4-750 M) at short-term (8-24 h) in nutrient solution. An increment in Mn concentration occurred early in roots of all genotypes at increased Mn...
Highbush blueberry (Vaccinium corymbosum L.) is an important crop well adapted to acid soils, but sensitive to Al3+ toxicity. Gypsum amendments are frequently used to reduce Al3+ toxicity in V. corymbosum. However, little is known about the physiological and metabolic responses to gypsum applicat...

The impact of increased artificial UV-B radiation on photosynthetic performance, antioxidant and SOD activities and molecular antioxidant metabolism responses in leaves of two highbush blueberry (Vaccinium corymbosum L. cv. Brigitta and Bluegold) genotypes was studied. Plants were grown in a soli...
Manganese (Mn) is an essential micronutrient for plants; however, in excess, it can have negative effects on their physiological and biochemical characteristics. We evaluate photosynthetic performance, antioxidant activity, and organic acid exudations to clarify the mechanisms involved in highbus...
