“…The exposure to sUV-B and heavy metal stress caused significant reductions in biomass accumulation and NPP. Similar reductions in the biomass yield were observed by Shukla et al (2002) in Triticum aestivum (wheat) seedlings due to the combined stress of UV-B and Cd. Haghiri (1973) also reported a sharp decline in the yield of dry matter in soybean and wheat at the lowest level of applied Cd (2-5 ppm).…”

“…Synergistic action of UV-B radiation and Cd was reported by Shukla et al (2002) on the growth of wheat seedlings. Prasad et al (2004) reported changes due to UV-B and Cd alone and in combination on photosynthetic pigments, photosynthetic electron transport activity, enzymatic and non-enzymatic antioxidants and lipid peroxidation in a liverwort, Riccia sp.…”

The impact of supplemental UV-B (sUV-B) radiation and heavy metals: Cd (68 µmol.kg -1 soil) and Ni (68 μmol.kg -1 soil) singly and in combination was studied on photosynthetic and non-photosynthetic pigments, metabolites, enzyme activities, biomass accumulation and the net primary productivity of spinach (Spinacia oleracea L. var. All Green), a common leafy vegetable plant. Both the stresses individually and in combination resulted in the reduction of photosynthetic pigments, ascorbic acid, and catalase activity, whereas a reverse trend was observed for anthocyanin, flavonoids and proline content, lipid peroxidation and peroxidase activity. The interactive effects of both the stresses were, however, less than additive. Combined treatment of sUV-B + Cd was more deleterious as compared to sUV-B + Ni and other individual treatments. Key words: Spinaicia oleracea, biomass, cadmium, enzymes, nickel, pigments, ultraviolet-B.Efeitos interativos entre radiação ultravioleta B suplementar e metais pesados no crescimento e características bioquí-micas de Spinacia oleracea L.: Estudou-se o impacto de radiação UV-B suplementar (sUV-B) e dos metais pesados Cd (68 µmol.kg -1 solo) e Ni (68 μmol.kg -1 solo), isoladamente ou em combinação, sobre pigmentos fotossintéticos e não fotossintéti-cos, metabólitos, atividades enzimáticas, acúmulo de biomassa e produtividade primária de espinafre (Spinacia oleracea L. var. All Green). Ambos estresses, individualmente ou em combinação, resultaram na redução dos pigmentos fotossintéticos, áci-do ascórbico, e atividade de catalase, sendo que uma tendência oposta foi observada para o conteúdo de antocianina, flavonói-des e prolina, peroxidação lipídica e atividade de peroxidase. Os efeitos interativos de ambos estresses foram, no entanto, menos que se fossem aditivos. O tratamento combinado de sUV-B + Cd foi o mais deletério quando comparado com sUV-B + Ni e outros tratamentos individuais.

“…An examination of more than 200 plant species reveals that roughly 20% are sensitive, 50% are mildly sensitive or tolerant and 30% are completely insensitive to UV-B radiation [3]. Whilst the impact of enhanced UV-B radiation on plant physiology, morphology, growth, nutrition, biomass and leaf quality have been investigated extensively [4][5][6][7][8][9][10][11][12], little is known about effect of enhanced UV-B radiation effects on grain quality and intraspecific differences in grain quality response to enhanced UV-B under field conditions [13], therefore further studies are required in this area.…”

“…FAA content was estimated following the method of Shukla et al (2002) with minor modifications to expand the test weight and volume in proportion. Fifty milligrams of ice-water bath ground fresh sample was stirred in 5 ml 10 % acetic acid (v/v) solution overnight and distilled water was added to adjust the total volume to 50 ml.…”

Phthalic acid esters (PAEs) pollution in agricultural soils caused by widely employed plastic products is becoming more and more widespread in China. PAEs polluted soil can lead to phytotoxicity in higher plants and potential health risks to human being. We evaluated the individual toxicity of di-n-butyl phthalate (DnBP) and bis (2-ethylhexyl) phthalate (DEHP), two representative PAEs, to sown rape (Brassica chinensis L.) seeds within 72 h (as germination stage) and seedlings after germination for 14 days by monitoring responses and trends of different biological parameters. No significant effects of six concentrations of PAE ranging from 0 (not treated/NT) to 500 mg kg −1 on germination rate in soil were observed. However, root length, shoot length, and biomass (fresh weight) were inhibited by both pollutants (except root length and biomass under DEHP). Stimulatory effects of both target pollutants on malondialdehyde (MDA) content, superoxide dismutase (SODase) activity, ascorbate peroxidase (APXase) content, and polyphenoloxidase (PPOase) activity in shoots and roots (SODase activity in shoots excluded) were in the same trend with the promotion of proline (Pro) but differed with acetylcholinesterase activity (except in shoots under DnBP) for analyzed samples treated for 72 h and 14 days.Responses of representative storage compounds free amino acids (FAA) and total soluble sugar (TSS) under both PAEs were raised. Sensitivity of APXase and Pro in roots demonstrates their possibility in estimation of PAE phytotoxicity and the higher toxicity of DnBP, which has also been approved by the morphological photos of seedlings at day 14. Higher sensitivity of the roots was also observed. The recommended soil allowable concentration is 5 mg DnBPkgsoil for the development of rape. We still need to know the phytotoxicity of DEHP at whole seedling stage for both the growing and development; on the other hand, soil criteria for PAE compounds are urgently required in China.
