“…The BCF means the ability of a plant species to uptake a metal into its root tissues from soil. The TF refers to the capacity of a plant to translocate the metal from its root to aerial parts [118][119][120]. The BCF and TF were calculated as follows: BCF = Metal concentration in plant tissue/metal concentration in soil (1) TF = Metal concentration in aerial tissue/Metal concentration in root (2)…”

A greenhouse pot trial was conducted to investigate the effect of organic amendments combined with triple superphosphate on the bioavailability of heavy metals (HMs), Amorpha fruticosa growth and metal uptake from Pb-Zn mine tailings. Cattle manure compost (CMC), spent mushroom compost (SMC) and agricultural field soil (AFS) were applied to tailings at 5%, 10%, 20% and 30% w/w ratio, whereas sewage sludge (SS) and wood biochar (WB) were mixed at 2.5%, 5%, 10% and 20% w/w ratio. Triple superphosphate (TSP) was added to all the treatments at 4:1 (molar ratio). Amendments efficiently decreased DTPA-extracted Pb, Zn, Cd and Cu in treatments. Chlorophyll contents and shoot and root dry biomass significantly (p < 0.05) increased in the treatments of CMC (except T4 for chlorophyll b) and SMC, whereas treatments of SS (except T1 for chlorophyll a and b), WB and AFS (except T4 for chlorophyll a and b) did not show positive effects as compared to CK1. Bioconcentration factor (BCF) and translocation factor (TF) values in plant tissues were below 1 for most treatments. In amended treatments, soluble protein content increased, phenylalanine ammonialyase (PAL) and polyphenol oxidase (PPO) decreased, and catalase (CAT) activity showed varied results as compared to CK1 and CK2. Results suggested that A. fruticosa can be a potential metal phytostabilizer and use of CMC or SMC in combination with TSP are more effective than other combinations for the in situ stabilization of Pb-Zn mine tailings.

“…Since there are inconsistent results from previous investigations, further studies need to explore useful information regarding the impact of biochar on white willow with different feedstock (broadleaf wood biochar) in HM-contaminated soils. Furthermore, the analysis of physiological and biochemical properties of the plants as stress indicators is considered to be useful in describing plant tolerance to HM stress as it provides information on how plants are affected by contaminants [24]. Along with these properties, growth analysis could also provide new insights into the plants' response to HM-contaminated soil amended by biochar.…”

Biochar is an efficient soil amendment used for promoting plant resistance to heavy metal (HM)-contaminated soils. There is a need for further investigation of its impacts on plants and soil. This study was undertaken as a pot experiment to assess the effect of biochar (0, 2.5, and 5% mass fractions) on the morphological, physiological and biochemical responses of white willow seedlings (Salix alba L.) cultured in uncontaminated soil and mixed soil contaminated with HM (Cu, Pb, and Cd). Additionally, some chemical properties and HM bioavailability were evaluated. Biochar increased height and diameter, root elongation, leaf area and dry biomass of the seedlings in both soils. Its addition to the contaminated soil reduced electrolyte leakage, the malondialdehyde and proline contents but increased the chlorophyll content, net photosynthesis rate, intercellular CO 2 concentration and transpiration rate in the leaf. Use of biochar (especially at 5% rate) in both soils, increased soil pH, total nitrogen, soil organic carbon and available P and K, while in the contaminated soil the availability of Cu, Pb, and Cd decreased. The results showed that biochar is a suitable amendment to contaminated soils that improves plant properties by improving soil chemical features and immobilizing HMs.Abbreviations: Brunauer-Emmett-Teller (BET); Barrett-Joyner-Halenda (BJH); intercellular CO 2 concentration (Ci); transpiration rate (E); electrolyte leakage (El); stomatal conductance (Gs); leaf area (LA); heavy metal (HM); malondialdehyde (MDA); total nitrogen (TN); scanning electron microscopy (SEM); specific leaf area (SLA); soil organic carbon (SOC); water use efficiency (WUE) Arch Biol Sci. 2019;71(2):281-291 https://doi.

“…Ψ reflects a plant's water status, and determines the plant's ability to maintain its water balance by absorbing water from the soil and from neighboring cells. The higher Ψ of S. longistamina and U. pumila suggests that they sustain better water relations under water-limited conditions than P. cathayana, probably as a result of their massive root system, which can exploit deep soil moisture [34,35]. The root system of Salix has strong root anchorage, which helps roots embed in soils, and Ulmus can generate new roots rapidly and thus increase root surface area [36].…”

This paper measured the ecophysiological responses of Populus cathayana Rehd., Salix longistamina C. Wang et P. Y. Fu., and Ulmus pumila L. to high altitude in the Tibetan Plateau based on changes in water relations, gas exchange, and chlorophyll fluorescence. P. cathayana and U. pumila have higher survival rates than S. longistamina, but the latter has highest biomass. S. longistamina has higher water-use efficiency (WUE), lower transpiration rates (E), higher water potential (Ψ), highest light saturation point (LSP) and higher photosystem II (PSII) photochemistry efficiency (F v '/F m ') and non-photochemistry quenching (NPQ) than the other species, and is thus adapted to its habitat for afforestation. U. pumila has lower E, light compensation point (LCP), dark respiration (R d ), F v '/F m ' and electron transport rate (ETR), with higher Ψ, apparent quantum yield (AQY), net photosynthetic rate (P n ) and non-photochemical quenching (NPQ), which helps it maintain water balance and utilize weak light to survive at high altitude. Relative low WUE, Ψ, R d , NPQ, with high E, P n , F v '/F m ' and biomass, imply that P. cathayana is more suitable for shelterbelt forests than for a semi-arid habitat. These three species can adapt to high-altitude conditions by different physiological mechanisms and morphological characteristics, which can provide a theoretical basis for afforestation and forest management in the Qinghai Tibetan Plateau.
