“…According to Abreu et al (2007), in soils with deficient drainage, compacted soils and those with pH values less than 5.5, Mn contents in the soil may reach levels which are toxic to plants. Studies show a close relationship between the Eh changes of flooded soils and plant metabolism, due to the increase in availability of ions such as Mn, Fe and Cu (Hauck et al, 2003;Dat et al, 2004;Shenker et al, 2004). Under conditions of excess Mn, there may be a decrease in uptake of other cations (Ca, Fe and Mg) and in the photosynthetic rate, and an increase in the activity of antioxidant enzymes, among them, superoxide dismutase (SOD), catalase and peroxidases (Wang et al, 2009;Mou et al, 2011).…”

SUMMARYEucalyptus Shoot Blight in the Vale do Rio Doce (ESBVRD) is an anomaly that leads to reduced growth and, in more extreme cases, to death of eucalyptus plants. Initially diagnosed in plantations in the region of the Vale do Rio Doce, in the State of Minas Gerais, Brazil, this problem has also been found in plantations in other regions of the country and even in other countries. Although the symptoms of this anomaly are well-known, its causes are not yet understood. The aim of this study was to evaluate the cause-effect relationship between accumulation of manganese (Mn) in eucalyptus clones and ESBVRD. Characterization of the environment in areas of greater occurrence of this problem in regard to soil, climate and fluctuation of the water table was undertaken in eucalyptus plantations of the Celulose Nipobrasileira S.A. (Cenibra) company in the region of the Vale do Rio Doce. Plant tissues were sampled in two situations. In the first situation, diagnosis occurred in the initial phase of the anomaly in clones with differentiated tolerance to the problem; in the second situation, diagnosis was made in a single clone, considered to be sensitive, in two time periods -in the phase with the strong presence of symptoms and in the recovery phase, in areas of occurrence and in areas of escape from the problem. The most ESBVRD-sensitive clone showed much higher (4.8 times higher) leaf Mn contents than more tolerant clones. In plants with the anomaly, Mn leaf contents were greater than 3,070 mg kg -1 , much greater than the quantity found in those without the anomaly (734 mg kg -1 ). In the period in which the symptoms began to wane, there was a sharp decline in leaf Mn contents, from 2,194 to 847 mg kg -1 .(1) Received for publication on February 27, 2013 and approved on October 25, 2013.(2) Researcher, Coordenação de Pesquisa e Desenvolvimento Florestal (GGF-P), Celulose Nipo-Brasileira S.A. -CENIBRA.Regional Manganese content in the above ground part and plant litter (44.4 g ha -1 ) in the area of occurrence of the anomaly was three times greater than that found in these same components (14.1 g ha -1 ) in the area of absence of the symptom. Based on the evidence found, such as the existence of environmental conditions favorable to high Mn availability to the plants in the areas of greatest incidence of ESBVRD, greater uptake of Mn in sensitive clones and in plants with symptoms, and a synchronism between the intensity of symptoms of ESBVRD and leaf Mn contents, it may be inferred that temporary excess of Mn in eucalyptus plants is closely related to ESBVRD.Index terms: hypoxia, groundwater, redox potential.

Heavy metal pollution has become an increasingly recognized threat to the aquatic environment. In response to heavy metal stresses, various terrestrial plants produce the hormone nitric oxide (NO), but minimal information is available about the role of NO in aquatic macrophytes under high zinc (Zn) stress. In this study, we measured physiochemical parameters in the leaves of Hydrilla verticillata exposed to Zn 2+ (10 mg l ) for 10 d. NO application partially reversed Zn-induced negative effects in parameters such as nutrient uptake, antioxidant enzymatic activities, and biomass, as compared to treatments with Zn alone. These results indicate that NO supply could mitigate Zn stress in H. verticillata, as a defense mechanism of the plant against Zn toxicity.
