“…The growing demand for wood accompanied by a reduction in the supply of the remaining natural forests has influenced the rapid expansion of plantations, in which Eucalyptus plays an important role, particularly in Brazil (Tadele and Teketay 2014). This genus comprises of species that present a broad adaptability to different types of soils and climates, rapid growth and multiple uses of the wood (Jenbere et al 2012;Neiva et al 2015).…”

& Key message Our research revealed that 24-epibrassinolide alleviated nickel toxicity in young Eucalyptus urophylla plants, inducing benefits on nutritional, physiological, biochemical, anatomical and morphological responses. & Context Soil contamination by heavy metals may limit the Eucalyptus production. Disturbances caused by nickel (Ni) toxicity interfere with the absorption of other essential nutrients. 24-Epibrassinolide (EBR) is one form of brassinosteroid (BR) that provides benefits for plant metabolism under Ni toxicity. & Aims The aim of this study was to determine whether exogenous EBR can improve ionic homeostasis by evaluating nutrient concentrations, anatomical characteristics and chlorophyll fluorescence in young Eucalyptus urophylla plants subjected to Ni toxicity. & Methods The experiment was randomized into four treatments, including two Ni concentrations (0 and 600 μM Ni) and two 24epibrassinolide concentrations (0 and 100 nM EBR). & Results EBR significantly reduced Ni contents. Plants exposed to Ni 2+ and sprayed with steroid had increases in the Ca 2+ /Ni 2+ and Mn 2+ /Ni 2+ ratios in the leaves of 38% and 15%, respectively, compared with the same treatment without EBR. The treatment of Ni 2+ toxicity + EBR presented an increase of 42% in effective quantum yield of PSII photochemistry, when compared with plants exposed to Ni without EBR. Ni toxicity induced negative effects on stomatal functionality, but EBR application mitigated these effects. & Conclusion Benefits on effective quantum yield of PSII photochemistry after EBR spray can be related to increases in manganese contents. EBR reduced oxidative stress, alleviating the deleterious effects induced by Ni toxicity and inducing positive repercussions on antioxidant enzymes, photosynthetic pigments and biomass.

“…An example includes in Ethiopia, where after five successive annual crop cycles, farmlands reclaimed from eucalypt stands increased total biomass and grain yield of finger millet by 31.8 and 25.4% respectively; and that of barley by 32.8 and 37% respectively (Tadele and Teketay, 2014). The authors observe that the soil conditions did not deteriorate in farmlands reclaimed from eucalypt plantations.…”

“…Many reports on crop yields as affected by trees when these are grown next to each other are usually presented as percentages or yields ha -1 relating values nearest to trees and those in open areas, far away from the trees (Sudmeyer and Hall, 2015;Tadele and Teketay, 2014;Chanie et al, 2013). This is very informative since it does not show actual proportional sizes of crops fields affected and those not affected, and the percentages are usually high, giving a wrong impressions to the readers of the magnitude of tree effects.…”

“…The recent uncontrolled expansion of Eucalyptus could have significant effects on various ecosystem processes (Kebebew and Ayele 2010;Jenbere et al 2012;Chanie et al 2013;Tadele and Teketay 2014;Jaleta et al 2016b). Eucalyptus expansion has been a contentious matter due to its argued ecological effects (Dessie and Erkossa 2011;Tadele and Teketay 2014;Yitaferu et al 2013;Jaleta et al 2016a).…”

Effect of Eucalyptus expansion on surface runoff in the central highlands of Ethiopia

Introduction: Land use/land cover change can affect the ecological processes of an area such as hydrological cycle. The change in the condition of water resources of an area could be a good indicator of changes in ecosystem function as a result of altered land use/land cover. Eucalyptus expansion in central Ethiopia is one of the recent land use/land cover changes causing controversy on its potential ecological effect. This study was designed to evaluate effects of three adjacent land uses/land covers, i.e. cultivated land, grassland and Eucalyptus woodlot on surface runoff in Meja River watershed, central Ethiopia. Methods:The rainfall amount at each study catchment was collected using the rain gauge installed to record daily rainfall amount. The three land use/land cover types in each study catchment were selected for comparison as treatments. Four replications of each land use/land cover were used forming a total of 12 runoff plots. The rainfall and runoff data were collected twice a day for 91 days. Results: The study found that land use/land cover significantly affects surface runoff generated from the plots. Higher runoff was recorded from cultivated land. There was no significant difference on runoff volume between grassland and Eucalyptus woodlot. Conclusions: This shows that expansion of Eucalyptus on grassland could not have significant impact on surface runoff generation but if planted on previously farmland could reduce surface runoff.
