10 sty 2023 · In an analysis performed on two different ecotypes of the Paubrasilia echinata tree, it was shown that UV-B radiation inhibited stem growth, biomass accumulation, CO 2 assimilation, and photochemical efficiency in a shade-tolerant ecotype inhibition; in contrast, a sun-tolerant ecotype showed a positive response: UV-B increased flavonoids ...
Stratospheric ozone depletion due to human activities has resulted in an increase of ultraviolet radiation on the Earth's surface. The article describes some effects on human health, aquatic ecosystems, agricultural plants and other living things, and explains how much ultraviolet radiation we are currently getting and how we measure it.
1 lut 2023 · These findings allow us to better assess the impacts of changes in UV radiation, plant response to rapid increases in UV radiation (as occur following many ECEs), and how UV radiation interacts with environmental stresses (e.g. climate change) to modulate their growth and productivity.
15 gru 2020 · The distinct bands of UV radiation, UV-A, UV-B, and UV-C have different effects on plants and their associated microorganisms. While UV-A and UV-B mainly affect morphogenesis and phototropism, UV-B and UV-C strongly trigger secondary metabolite production.

15 wrz 2014 · Sunlight provides the necessary energy for plant growth via photosynthesis but high light and particular its integral ultraviolet (UV) part causes stress potentially leading to serious damage to DNA, proteins, and other cellular components.
24 cze 2019 · Changes in stratospheric ozone and climate over the past 40-plus years have altered the solar ultraviolet (UV) radiation conditions at the Earth’s surface. Ozone depletion has also contributed...
