“…On the acidic clay site, Mn was 610 ppm; whereas, mean values of Mn at 850 ppm have been reported [68]. Bourret et al [9] found foliar Mn concentrations ranging from approximately 350 ppm in Salix geyeriana Andersson, to 150 ppm in S. monticola Bebb growing in unsaturated mine tailings.…”

“…Salinity can cause the accumulation of high concentrations of ions such as Na, Cl, and SO 4 [67]. Some species do not show much increase in salt concentration over time and thus can avoid leaf mortality, whereas other species exclude or store salt in vacuoles, thereby controlling uptake and compartmentalization of ions such as Na, Cl, Fe, and S [68,69]. Among these ions, Na is considered the main ion negatively affecting plant growth.…”

Plants regularly experience suboptimal environments, but this can be particularly acute on highly-disturbed mine sites. Two North American willows-Salix discolor Muhl. (DIS) and S. eriocephala Michx. (ERI)-were established in common-garden field tests on two adjacent coal mine spoil sites: one with high clay content, the other with shale overburden. The high clay content site had 44% less productivity, a pH of 3.6, 42% clay content, high water holding capacity at saturation (64%), and high soil electrical conductivity (EC) of 3.9 mS cm −1 . The adjacent shale overburden site had a pH of 6.8, and after removing 56.5% stone content, a high sand content (67.2%), low water holding capacity at saturation (23%), and an EC of 0.9 mS cm −1 . The acidic clay soil had significantly greater Na (20×), Ca (2×), Mg (4.4×), S (10×), C (12×) and N (2×) than the shale overburden. Foliar concentrations from the acidic clay site had significantly greater Mg (1.5×), Mn (3.3×), Fe (5.6×), Al (4.6×), and S (2×) than the shale overburden, indicating that these elements are more soluble under acidic conditions. There was no overall species difference in growth; however, survival was greater for ERI than DIS on both sites, thus overall biomass yield was greater for ERI than DIS. Foliar concentrations of ERI were significantly greater than those of DIS for N (1.3×), Ca (1.5×), Mg (1.2×), Fe (2×), Al (1.5×), and S (1.5×). There were no significant negative relationships between metal concentrations and growth or biomass yield. Both willows showed large variation among genotypes within each species in foliar concentrations, and some clones of DIS and ERI had up to 16× the Fe and Al uptake on the acidic site versus the adjacent overburden. Genetic selection among species and genotypes may be useful for reclamation activities aimed at reducing specific metal concentrations on abandoned mine sites. Results show that, despite having a greater water holding capacity, the greater acidity of the clay site resulted in greater metal mobility-in particular Na-and thus a greater EC. It appears that the decline in productivity was not due to toxicity effects from the increased mobility of metals, but rather to low pH and moisture stress from very high soil Na/EC.

“…It is estimated that about 2/3 of world population will experience a water deficiency at medium or high level by the year 2025 (EPA, 2004). World total water resources is 1.4 billion m 3 (DSİ, 2012) and only 1% of this amount is used as potable water (Cassaniti et al, 2013). Total surface and groundwater resources of Turkey are 112 million m 3 and about 40% of this amount is actively used today.…”

Ever increasing demands for fresh water resources have brought the reuse of treated wastewater into agendas. Wastewater has year-long potential to be used as an irrigation water source. Therefore, treated wastewater is used as irrigation water over agricultural lands and urban landscapes, as process water in industrial applications, as back-up water in environmental applications in water resources and wetlands of dry regions. The present study was conducted to investigate the possible use of domestic wastewater treated through pilot-scale constructed wetland of Adana-Karaisalı with dominant Mediterranean climate in irrigation of marigold (Tagetes erecta), commonly used over urban landscapes. Experiments were carried out between the dates May-November 2008 for 7 months with fresh water and treated wastewater. Plant growth parameters (plant height, plant diameter, number of branches) and flowering parameters (number of flowers, flower diameter, flower pedicle thickness) were monitored in monthly basis. Results revealed positive impacts of treated wastewater irrigations on plant growth during the initial 5 months between May-September but negative impacts in October and November. Similarly, treated wastewater irrigations had positive impacts on flowering parameters during the initial 3 months but had negative impacts during the subsequent 4 months. Such a case indicated shortened visual efficiencies of marigold. Therefore, treated wastewater can be used as an alternative water resource in irrigation of annual flowers, but better results can be attained by mixing treated wastewater with fresh water at certain ratios.

“…In the case of ornamental plants, it is also fundamental to evaluate the effects on plant quality particularly relative to the visual aspect, based on analysis by the future consumers, because the beauty in the acquisition of an ornamental plant is not always associated with its size (Cassaniti et al, 2013).…”

A B S T R A C TThe development of agriculture in the northeastern semi-arid region depends, at least in part, on the correct exploitation and efficient use of natural resources. The objective of this study was to evaluate the effects of the use of saline water on morphophysiological responses and sensory analysis of 'Boa noite' plants (Catharanthus roseus) in soil fertilized with bovine biofertilizer. A completely randomized design was used in the split plot arrangement, the plots being formed by the five irrigation water salinity levels (0.5, 2.5, 5.0, 7.5 and 10 dS m -1 ), and the subplots by two frequencies of application of the 150 mL pot -1 of liquid bovine biofertilizer (divided into one and five times), with five replicates. The analysed variables were: leaf gas exchange relative chlorophyll index, biometry, dry matter (leaf, stems, flowers and roots) and sensory analysis (general appearance and buyers' preference). Quantitative (growth and physiological) and qualitative (sensory analysis) responses show that Catharanthus roseus plants can be produced using saline water at the level of 2.5 dS m -1 , and the plants of this treatment were preferred by the judges in sensory analysis. Biofertilizer application frequency did not attenuate the effects of salinity. Therefore, the liquid bovine biofertilizer can be applied all at once, reducing costs.Respostas quantitativas e qualitativas de Catharanthus roseus à salinidade e biofertilizante R E S U M O O desenvolvimento da agricultura no semiárido nordestino depende, sobretudo, da exploração correta e do uso eficiente dos recursos naturais. Objetivou-se avaliar os efeitos do uso de águas salinas, em solo adubado com biofertilizante bovino, sobre as respostas morfofisiológicas e na qualidade (análise sensorial) de plantas de Boa noite (Catharanthus roseus). Usou-se o delineamento inteiramente casualizado com tratamentos arranjados em parcelas subdivididas, sendo as parcelas formadas por cinco níveis de salinidade da água de irrigação (0,5; 2,5; 5,0; 7,5 e 10 dS m -1 ) e as subparcelas por duas frequências de aplicação da dose de 150 mL de biofertilizante bovino líquido por vaso (dividida em uma e cinco vezes), com cinco repetições. As variáveis analisadas foram: trocas gasosas foliares índice relativo de clorofila, biometria, matéria seca de folhas, hastes, flores e raízes e análise sensorial (aparência geral e preferência dos compradores). Com as análises quantitativas (crescimento e fisiológicas) e qualitativas (análise sensorial), notou-se que plantas de Catharanthus roseus de cor branca podem ser produzidas utilizando-se água salina em nível de 2,5 dS m -1 , sendo as plantas deste tratamento as preferidas dos julgadores na análise sensorial. A frequência de aplicação do biofertilizante não atenuou os efeitos da salinidade. Desta forma, pode-se aplicar o biofertilizante bovino líquido de uma única vez, diminuindo custos.
