“…This result is in agreement with a number of papers showing Pb-induced inhibition of photosynthesis accompanied by stomatal closure (Ahmad et al, 2008;Islam et al, 2008;Kosobryukhov et al, 2004;Li et al, 2012). Unlike photosynthesis, the decrease in the chlorophyll content in Plantago leaves in response to Pb treatment was not observed in the present work.…”

“…The moderately high temperature of incubation (28 o C) increased stomatal resistance compared to that at 20 o C, which was shown to be optimal for Plantago photosynthesis (Kosobryukhov et al, 2004). The inhibitory effects of temperatures increasing from 22 to 32°C on the photosynthesis rate and transpiration were described by Lipiec et al (2013).…”

A b s t r a c t. Fluctuation of the summer day-time temperatures in the mid-latitudes in a range from 16 to 30 o C should not have irreversible negative effects on plants, but may influence metabolic processes including the oxidative stress. To test the effect of moderately high temperature on oxidative stress induced by lead in the leaves of Plantago major L.; the plants were incubated in a water solution of 0, 150, 450, and 900 µM Pb(NO 3 ) 2 at 20 and 28 o C. Plant reactions were evaluated by the content of thiobarbituric acid reactive substances and ascorbate peroxidase and glutathione reductase activities in leaves after 2, 24, 48, and 72 h. The Pb concentration in the leaves rose with the increase in the Pb content and was higher at 20 o C. The increase in stomatal resistance caused by Pb was higher at 28 o C. The contents of TBARS increased after 2 h of plant exposure to Pb and the increase was the highest at 900 µM Pb, 28 o C. The AsP activity increased up to 50% after 24 h of Pb-treatment at 28 o C; the highest increase in glutathione reductase activity was observed after 72 h at 20 o C. Thus, the moderately high temperature 28 o C compared with optimal 20 o C caused a decrease in Pb accumulation in Plantago leaves but amplified the negative effects of lead, especially in the beginning of stress development.K e y w o r d s: ascorbate peroxidase, glutathione reductase, lead, heat stress, oxidative destruction, Plantago major L.

“…Uveges et al (2002) também constataram reduções lineares na matéria seca da planta inteira de Lythrum salicaria submetidas a doses crescentes de Pb em solução (0 a 2.000 mg L -1 ). Kosobrukhov et al (2004), em trabalho avaliando o efeito do incremento do teor de Pb no solo sobre o crescimento de plantas de Plantago major, constataram reduções na matéria seca da planta inteira de 30 e 46 %, em relação à testemunha, em solo contaminado com 500 e 2.000 mg kg -1 de Pb, respectivamente.…”

“…desses atributos (Figuras 2; 3-A e 3-B). Segundo KOSOBRUKHOV et al (2004), a aplicação de Pb provoca considerável decréscimo na massa seca de partes de plantas. Em Vetiver zizanioides e V. nemoralis a biomassa das plantas diminuiu com o aumento da concentração de Pb aplicada (CHANTACHON et al, 2004).…”

RESUMOA fitoextração é uma importante técnica usada para descontaminar áreas poluidas por metais pesados. Conseqüentemente, o entendimento das respostas fisiológicas de espécies tropicais com relação à tolerância aos níveis crescentes de contaminantes é fundamental considerando seu possível uso para fitoextração de metais pesados de áreas contaminadas. O objetivo deste estudo foi conhecer o potencial fitoextrator de Canavalia ensiformes L. para o chumbo (Pb). As plantas foram cultivadas em solução nutritiva em casa de vegetação sobre condições parcialmente controladas. O Pb foi testado nas concentrações de 100, 200 e 400 mmol.L -1 . O experimento foi montado em blocos ao acaso, usando um esquema fatorial 4 x 1, com três repetições. Foram realizadas análises fisiológicas com o acompanhamento de sintomas, das massas frescas e secas tanto da parte aérea como das raízes, da área foliar, das alturas das plantas e do conteúdo de Pb na solução nutritiva, nas raízes e na parte aérea das plantas. As amostras das plantas (parte aérea e raiz) e da solução nutritiva foram submetidas às análises químicas para determinação de Pb usando a digestão via seca. As plantas de Canavalia ensiformes foram boas acumuladoras e tolerantes ao Pb, demonstrando seu potencial como fitoextratoras para esse metal.Palavras-chave: fitoextração, metal pesado, sistema hidropônico. LEAD UPTAKE AND POTENTIAL FOR FITOREMEDIATION OF CANAVALIA ENSIFORMES L. (1) ABSTRACTPhytoextraction is an important technique used for decontamination of areas polluted by heavy metals. Consequently, understanding the physiological responses in relation to the tolerance of tropical species subjected to increasing levels of contamination is fundamental before considering their use as phytoextractans in contaminated areas. The objective of our study was to assess the potential of Canavalia ensiformes L. for the phytoextraction of lead (Pb). Plants were cultivated with nutrient solution in greenhouse under partially controlled conditions. Pb was tested at concentrations of 100, 200 and 400 µmol.L -1 . The experimental set-up was a randomized blocks design, using a 4 x 1 factorial scheme, with three replicates. Follow-ups of physiological symptoms were carried out, determining fresh and dried mass for shoot and root, leaf area, plant height, Pb content in nutrient solution and in roots and shoot of the plants. The samples of shoot and roots and of the nutrient solution were submitted to chemical analysis for the determination of Pb, using dry digestion. The Canavalia ensiformes plants proved to be both accumulators and tolerant to Pb, demonstrating their potential as a phytoextractants.
