“…They even found a decrease of P N , g s and E for 1 mM in comparison to control. Similar results were also obtained in four Datura species, where similar Zn solutions were applied, and they showed a decrease of P N and g s , while C i increased together with Zn increase in the medium (Vaillant et al 2005). …”

“…It is the only metal represented in all six enzyme classes (Broadley et al 2007). At appropriate concentrations, zinc increases plant productivity, growth and development of fruits (Vaillant et al 2005). The beneficial role of zinc is limited due to its concentration in the environment, as well as in plants, and its level is quite narrow: 15-100 ppm (Clemens 2006).…”

Key message Zn caused an increase of photosynthesis activity, carbohydrates and chlorophyll at the level 1-2.5 mM, while phenols revealed a continuous increase together with Zn increase in the medium. Abstract The aim of the present study was to determine the effect of various Zn application levels on some physiological, morphological and biochemical parameters of a hybrid Salix purpurea 9 triandra 9 viminalis 2. Plants were cultivated under control conditions with application of Zn in the range 0-5 mM. The effects on net photosynthesis rate (P N ), stomatal conductance (g s ), transpiration rate (E), intercellular CO 2 (C i ), chlorophyll a and b, carotenoids, growth, sugars and phenols were analysed. Our investigations confirmed a dual role of Zn, with benefits at the level 1-2.5 mM, and a decrease of measured photosynthesis activity, carbohydrates and chlorophyll below and above this range. Moreover, the decrease of these parameters at the highest Zn application did not reach the level of control plants. This means that this species may have further potential as an accumulator in polluted areas. However, phenols revealed a continuous increase together with Zn increase in the medium.

“…The distribution of trace metal ions generally can be arranged as follows: roots > stems > leaves > fruit > seeds (Jin et al 2005). The uptake of metal ions by the plants depends not only on the content of the compounds of these elements in the soil, but also on the affi nity of the plant in relation to the metal (Krzesłowska et al 2010, Peralta-Videa et al 2009, Vaillant et al 2005, Lehmann and Rebele 2004.…”

Abstract:The article presents the results of research which describes antagonism between Pb-Zn in selected plant species from the area of Czestochowa -Mirow district (north-western part of the Czestochowa Upland). There were analyzed changes in the ratio of Pb/Zn in different organs of the tested plants as a function of the Zn content changes. The content of metals in the plants and the soil was determined using atomic absorption spectrophotometry AAS. In all organs of the plants there was observed antagonistic decrease of Pb uptake and accumulation, resulting from the increase in the concentration Zn.Antagonism between Zn and Pb in roots of the tested plants occurred at Zn content of 200-600 μg/g. In turn, antagonism in stems and fl owers occurred at lower contents of zinc (100-180 μg/g). In leaves, antagonism between Pb and Zn occurred when Zn was present at the level of 300-800 μg/g.Ex defi nition of the analyses confi rm the presence of antagonism of lead with regard to high levels of Zn. The study also confi rmed that the degree of antagonism depends on the plant species.

“…8 A determinação do nível supra-ótimo de Zn para a cultura do feijão poderá gerar alternativas para a ocupação de áreas com maiores concentrações do nutriente, de modo a propor a revegetação de áreas consideradas impraticáveis ao uso agrícola. 14,15,5,16 Atualmente são poucos os estudos que empregam a cultura do feijão em solos com excesso de Zn e pouco se conhece especificamente sobre o desenvolvimento de plantas nessas condições.…”

Objetivou-se com este estudo avaliar os efeitos da aplicação de solução nutritiva com concentrações crescentes de zinco (Zn) no desenvolvimento inicial e no teor de pigmentos de plantas de feijão cultivadas em condições de casa de vegetação. O experimento foi desenvolvido no Laboratório de Nutrição de Plantas (LNP) e em casa de vegetação pertencentes ao Departamento de Botânica da Universidade Federal de Pelotas (UFPel). A semeadura foi realizada em vasos preenchidos com areia média lavada. Sete dias após a emergência das plântulas foi aplicada, com intervalos de dois dias, solução nutritiva com quatro concentrações crescentes de Zn (2, 50, 75 e 100 µM), dispostas em um delineamento experimental inteiramente casualizado com quatro repetições, sendo cada uma delas composta por seis plantas. Aos 45 dias após a emergência das plântulas, avaliaram-se as seguintes variáveis: altura das plantas, diâmetro do caule, número de folhas, área foliar e comprimento de raiz, além do índice de pigmentos fotossintéticos. Com o aumento das concentrações de Zn verificou-se decréscimo significativo para as variáveis diâmetro do caule e comprimento de raiz, sugerindo que maiores concentrações de Zn podem influenciar negativamente no desenvolvimento das plantas de feijão. Os índices de clorofila e flavonoides apresentaram elevação com o aumento das doses de Zn. Esse efeito possivelmente está relacionado a uma reação estratégica da espécie, que visa minimizar o efeito tóxico das concentrações crescentes de Zn no desenvolvimento das plantas.Palavras-chave: Feijão.
