“…Literature research revealed that applied doses of UV-B radiation vary widely, both in terms of daily dose applied (e.g. 12, 13·3, 24, 49, 2·6 or 4·9 kJ/m 2 ) and duration of radiation treatment in general, ranging from 4 days to 12 weeks (Burchard et al 2000; Hofmann et al 2000; Nogues & Baker 2000; Alexieva et al 2001; Skórska & Szwarc 2007; Calderini et al 2008; Majer & Hideg 2012). The UV-B radiation reaching the earth's surface is much smaller than UV-A due to atmospheric depletion, but in the shorter wavelength of the UV-B region many biological responses are far greater (Madronich et al 1998).…”

Correlating physiological parameters with biomarkers for UV-B stress indicators in leaves of grapevine cultivars Pinot noir and Riesling

SummaryThe robustness of seven physiological parameters together with two potential biomarkers for ultraviolet (UV)-B stress assessment was tested in greenhouse assays on the Vitis vinifera L. cultivars Pinot noir and Riesling. Effects of year, UV-B treatment, cultivar and clone were studied in four individual experiments. Grapevine plants were exposed to three dosed UV-B stress treatments (−UV-B: no UV-B radiation; +UV-B: daily dose of 4856·3 J/m2 UV-BBE; ++UV-B: daily dose of 7025·3 J/m2 UV-BBE) to detect changes of chlorophyll fluorescence and gas exchange parameters. Significant correlations between the leaf polyphenols quercetin-3-O-glucoside and kaempferol-3-O-glucoside with the maximum fluorescence (Fm), the variable fluorescence (Fv) and the maximum quantum yield for photosystem (PS) II (Fv/Fm) were found, which confirmed the biomarkers’ relevance, additionally validated by cultivar- and year-independency.

“…Epicuticular wax variability in triticale and its impact on cuticular transpiration has not been sufficiently investigated. Difference in epicuticular wax between two triticale varieties was associated with UV-B radiation tolerance, where the high wax cultivar was relatively more resistant (Skórska and Szwarc 2007). Saulescu et al (2011) concluded that rye and triticale had higher albedo than most wheat cultivars and they considered these species as genetic resources for improving this trait in wheat.…”

The abiotic stress response and adaptation of triticale — A review

After a decade of genetic manipulation and improvement, triticale stand out as a crop of high biomass and grain yield potential which generally surpass that of wheat. Its high productivity is most likely derived from high rates of carbon assimilation linked to stomatal physiology and probably low respiration rate. Being a derivative of rye, triticale has always been assumed to be relatively resistant to abiotic stress. The last review of triticale adaptation to abiotic stress as published by Jessop (1996) pointed at its general and specific fitness to harsh growing conditions. This review as based on additional data published in the last 20 years indicates that triticale retain good to excellent adaptation to conditions of limited water supply and problem soils which involve salinity, low pH, defined mineral toxicities and deficiencies and waterlogging. Despite the understandable expectations, freezing tolerance of triticale was not found to be up to the level of rye. The freezing tolerance of the rye complement in triticale is inhibited by unknown factors on the wheat parent genome. Any given triticale cultivar or selection cannot be taken a priori as being stress resistant. Research has repeatedly shown that triticale presented large genetic diversity for abiotic stress resistance and most likely this diversity has not yet been fully explored due to the very limited research and the small studied sample of the potential triticale germplasm. Triticale is a valuable stress tolerant cereal on its own accord and a potential genetic resource for breeding winter and spring cereals. Because of its high productivity and resilience it might become as important as wheat or better on a global scale if its grain technological quality will be improved to the level of wheat.

“…Protective responses stimulated by UV-radiation include increase in production of UV-absorbing compounds and secondary compounds including hydroxyl cinnamic acid derivatives, phenylpropanoids, and flavonoids which effectively absorb the UV-radiation (Hofmann et al 2000, Skórska andSzwarc 2007). Anthocyanins also have a wide distribution in mature and senescent leaves.…”

The effects of salicylic acid on pigment contents in ultraviolet radiation stressed pepper plants

et al. 2008

View full text Add to dashboard Cite

Pepper (Capsicum annuum L.) plants were sprayed with salicylic acid (SA) and treated with ultraviolet radiation UV-A (320-390 nm), UV-B (312 nm), and UV-C (254 nm) of 6.1, 5.8, and 5.7 W m -2 , respectively. UV significantly reduced contents of chlorophyll (Chl) a and b, and carotenoids (Car). SA treatment moderated Chl and Car reduction in plants treated with UV-B and UV-C. The quantity of antocyanins, flavonoids, rutin, and UV-absorbing compounds in plants that were treated with UV-B, UV-C, and SA were significantly increased. Foliar spray of SA counteracted the UV effects on pepper.
