“…Plants of Phaseolus vulgaris L. treated with 100 mg L -1 of Ni showed chlorotic leaves with gray spots that coalesced and became necrotic (Campanharo et al, 2010). Symptoms like chlorosis and necrosis can occur due to the excess of Ni (Seregin and Kozhevnikova, 2006), but other essential metals also can cause them (Khalid and Tinsley, 1980). This may be due to the fact that Ni has some characteristics that are similar to calcium, magnesium, manganese, iron, copper and zinc (Yusuf et al, 2011).…”

The heterosporous fern Regnellidium diphyllum occurs in southern Brazil and some adjoining localities in Uruguay and Argentina. Currently it is on the list of threatened species in the state of Rio Grande do Sul. Anthropic alterations such as the conversion of wetlands into agricultural areas or water and soil contamination by pollutants may compromise the establishment and survival of this species. Nickel (Ni) is an essential nutrient for plants but increasing levels of this metal due to pollution can cause deleterious effects especially in aquatic macrophytes. Megaspore germination tests were performed using Meyer's solution, at concentrations of 0 (control), 0.05, 0.5, 1, 5, 10, 20, 30, 50 and 100 mg L -1 of Ni. The initial development of apomictic sporophytes was studied using solutions containing 0 (control) to 4.8 mg L -1 of Ni. A significant negative relation was observed between the different Ni concentrations and the megaspore germination/ sporophyte formation rates. Primary roots, primary leaves and secondary leaves were significantly shorter at 3.2 and 4.8 mg L -1 of Ni, when compared with the treatment without this metal. At 4.8 mg L -1, leaves also presented chlorosis and necrosis. The introduction of pollutants with Ni in the natural habitat of Regnellidium diphyllum may inhibit the establishment of plants in the initial stage of development, a problem to be considered in relation to the conservation of this species.Keywords: heavy metals, megaspore, germination, sporophyte, pollution. Efeitos do níquel sobre a filicínea Regnellidium diphyllum Lindm. (Marsileaceae) ResumoA samambaia heterosporada Regnellidium diphyllum Lindm. ocorre no Sul do Brasil e em algumas localidades vizinhas no Uruguai e na Argentina. Atualmente, consta da lista de espécies ameaçadas do Estado do Rio Grande do Sul. Alterações antrópicas -tais como a conversão de áreas úmidas em áreas de agricultura ou a contaminação de água e solo por poluentes -podem comprometer o estabelecimento e a sobrevivência da espécie. Níquel (Ni) é um nutriente essencial às plantas, mas níveis aumentados desse metal, em razão da poluição, podem causar efeitos deletérios, especialmente em macrófitas aquáticas. Testes de germinação de megásporos foram realizados usando-se solução de Meyer, em concentrações de 0 (controle); 0,05; 0,5; 1; 5; 10; 20; 30; 50; 100 mg L -1 de Ni. O desenvolvimento inicial de esporófitos apomíticos foi estudado usando-se soluções contendo 0 (controle) a 4,8 mg L -1 de Ni. Relação negativa significante foi observada entre diferentes concentrações de Ni e as taxas de germinação de megásporos/formação de esporófitos. Raízes primárias e folhas primárias e secundárias foram significantemente mais curtas a 3,2 e 4,8 mg L -1 de Ni, quando comparadas ao tratamento sem esse metal. Em 4,8 mg L -1 , folhas também apresentaram clorose e necrose. A introdução de poluentes com Ni no habitat natural de Regnellidium diphyllum pode inibir o estabelecimento de plantas em estádio inicial de desenvolvimento, um problemaa a ser consider...

“…One of the probable mechanisms for decreasing the uptake of macro-and micro-nutrients by Ni relies on the competition for common binding sites due to comparable ionic radii of Ni (Emsley, 1991). The reduced uptake of Mg and Fe is one of the prime causes of chlorosis induced by excess of environmental Ni (Piccini and Malavolta 1992;Khalid and Tinsley 1980). The decline in nutrient uptake may also result from Ni-induced metabolic disorders that affect the structure and enzyme activities of cell membranes (Seregin and Ivanov 2001).…”

“…The effects of Ni on nutrient uptake depend on the Ni concentration in the environment. Experiments with ryegrass demonstrated that Fe content in the shoots increased at low Ni concentrations and decreased at higher concentrations (Khalid and Tinsley 1980). An increase in soil Ni content from 50 to 200 mg/kg soil decreased the contents of Cu and Mg in the caryopses and Mg and Ca in the shoots of T. aestivum (Barsukova and Gamzikova 1999).…”

The focus of the review is on the specific aspects of nickel's effects on growth, morphology, photosynthesis, mineral nutrition and enzyme activity of plants. The mobility of nickel in the environment and the consequent contamination in soil and water is of great concern. Also, the detrimental effects of excessive nickel on plant growth have been well known for many years. Toxic effects of nickel on plants include alterations in the germination process as well as in the growth of roots, stems and leaves. Total dry matter production and yield was significantly affected by nickel and also causes deleterious effects on plant physiological processes, such as photosynthesis, water relations and mineral nutrition. Nickel strongly influences metabolic reactions in plants and has the ability to generate reactive oxygen species which may cause oxidative stress. More recent evidence indicates that nickel is required in small amounts for normal plant growth and development. Hence, with the increasing level of nickel pollution in the environment, it is essential to understand the functional roles and toxic effects of nickel in plants.

“…Many plants that naturally grow on such contaminated soils contain Ni 2+ in concentrations exceeding 1000 mg g -1 DW in their tissues (Gonnelli et al 2001) but they generally possess mechanisms allowing them to tolerate Ni 2+ and to develop without phytotoxic problems (Gabbrielli et al 1990). However, many of agriculturally important crops contain less than 5 μg of Ni g -1 DW, and the symptoms of phytotoxicity often become apparent at soil Ni 2+ concentrations as low as 25-30 μg g -1 (Khalid and Tinsley 1980).…”

-The present study investigated the impact of nickel (Ni 2+ ) on trans-membrane electrical potential (E M ) and permeability properties of plasma membrane (PM) in epidermal cells of adventitious grapevine roots. The relationship between disturbances of membrane functionality and the production of superoxide anion, hydrogen peroxide and cell viability after the exposure of roots to Ni 2+ was also studied. Treatments with 0.1-5 mmol L -1 NiCl 2 induced a concentration-dependent transient PM depolarization, which was recovered to the initial resting potential within 50-70 min in the presence of Ni 2+ . Longer (up to 24 h) exposure of roots to 1 mmol L -1 of Ni 2+ hyperpolarized the E M by approximately 17 mV. Application of the highest 5 mmol L -1 concentration of Ni 2+ during longer treatments (up to 48 h) resulted in the increase of membrane permeability; however the E M , cell viability, and superoxide content remained unaffected. The increase in the formation of hydrogen peroxide was time-and concentration-dependent and maximum production was recorded after 180 min of Ni 2+ treatment. We can conclude that oxidative stress resulting from an imbalance in the generation and/ or removal of hydrogen peroxide in the root tissues of grapevine was the major cause of Ni 2+ toxicity.
