The impact of elevated UV-B (280–320 nm) radiation levels on the reproduction biology of a highland th populations individual seed mass as well as seed germination percentages were unaffected by the UV-B flux received by the parental plant. Possible effects of UV-B induced alterations in reproductivity on the geographical distribution of the different populations are discussed.作者: 上釉彩 時間: 2025-3-22 00:35 作者: 仔細(xì)閱讀 時間: 2025-3-22 04:53
Reaction of savanna plants from Botswana on UV-B radiationcantly decreased and supported the tendency of decreased biomass of UV-B radiated plants. It is concluded that from the investigated savanna species the grasses are relatively well adapted to increased UV-B due to their actual exposure to high UV-B radiation under Botswana conditions, whereas saplings of . are more sensitive to UV-B radiation.作者: MEN 時間: 2025-3-22 09:01
Effects of acute and chronic UV-B exposure on a green alga: a continuous culture study using a compun cell division rate and an increase in the cellular content of proteins, carbohydrates and chlorophyll . was measured. Transition experiments showed that complete acclimatisation to UV-B took several cell cycles. DNA damage appears to be the major cause of the observed long-term UV-B effects.作者: Anticonvulsants 時間: 2025-3-22 16:22
Outdoor supplementation systems for studies of the effects of increased UV-B radiationuring the past 3 years. These supplementation systems differ in their methods of operation, equipment, UV-B exposure regime and experimental design. This essay surveys the systems currently developed, considers problems associated with their use and discusses these in relation to the interpretation of biological effects.作者: BROOK 時間: 2025-3-22 20:42
Penetration and effects of solar UV-B on phytoplankton and macroalgae and the penetration of solar radiation into different water types (coastal and oceanic waters of the Baltic Sea, North Sea, Atlantic and Mediterranean) were investigated.

Morphological and physiological responses of bean plants to supplemental UV radiation in a Mediterraat may occur because of stratospheric ozone depletion; most of them were performed in controlled environment conditions where plants were exposed to low photosynthetically active radiation (PAR) levels and high UV-B irradiance.

Ultraviolet-B radiation effects on the Mediterranean ruderal Dittrichia viscosanchanged. Internal (cellular) UV-B absorbing compounds and chlorophylls were unaffected, but total carotenoids were increased, indicating a possible protective role against UV-B radiation damage.

Effects of solar UV-B radiation on growth, flowering and yield of central and southern European bushja, Primel, Manata and Cannellino exhibited no UV-B effects on weight and leaf area. A flowering delay of up to 1 day was observed under intense UV-B in several cultivars.
