    The Effect of Bamboo Charcoal Application on Soil Nutrients and Heavy Metals in Rice

    Guangyue Cai1, Juanli Tu2, Songhao Li3, Yifei Ruan3, Qifeng Wu3, Jiasen Wu1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.6, pp. 1245-1256, 2022, DOI:10.32604/phyton.2022.019599

    Abstract Soil heavy metal pollution is becoming more and more serious. Biomass charcoal application can play an important role in alleviating the toxicity of heavy metals in soils. Compared with other biochar, bamboo charcoal has more unique properties and may have a unique effect on heavy metal pollution. Zhejiang Province of Southeastern China is rich in bamboo resources. However, few studies related to bamboo charcoal application for heavy metal remediation in farmland were reported. In this study, four treatments with different amounts of bamboo charcoal application were set up through a field experiment, namely BC0 (no bamboo charcoal application), BC1 (2500 kg⋅ha−1),… More >

    Application of ferrous sulfate alleviates negative impact of cadmium in rice (Oryza sativa L.)


    BIOCELL, Vol.45, No.6, pp. 1631-1649, 2021, DOI:10.32604/biocell.2021.014934

    Abstract Soil contamination with toxic heavy metals [such as cadmium (Cd)] is becoming a serious global problem due to rapid development of social economy. Iron (Fe), being an important element, has been found effective in enhancing plant tolerance against biotic and abiotic stresses. The present study investigated the extent to which different levels of Ferrous sulphate (FeSO4) modulated the Cd tolerance of rice (Oryza sativa L.), when maintained in artificially Cd spiked regimes. A pot experiment was conducted under controlled conditions for 146 days, by using natural soil, mixed with different levels of CdCl2 [0 (no Cd), 0.5 and 1 mg/kg]… More >

    Integrated Fertilization Regimes Boost Heavy Metals Accumulation and Biomass of Sedum alfredii Hance

    Kangning Zhou1, Yingying Zhang1, Jiasen Wu1, Chunying Dou1,2, Zihao Ye1, Zhengqian Ye1,3,*, Weijun Fu1,3,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.4, pp. 1217-1232, 2021, DOI:10.32604/phyton.2021.014951


    The hyperaccumulator Sedum alfredii Hance (S. alfredii) may be employed for zinc (Zn) and cadmium (Cd)-polluted soil remediation. However, the low phytoremediation efficiency, related to the low biomass production, limits its use with that purpose. In this experiment, nitrogen (N), phosphorus (P), and potassium (K) fertilizers, and organic manure were applied to investigate the phytoremediation ability of S. alfredii. Hydroponic and pot experiments were conducted using Zn-Cd polluted soil. The hydroponic experiment indicated that appropriate fertilizer application could increase (p < 0.05) the amount of accumulated Zn and Cd in S. alfredii. When N supply ranged from 0.5 to 2.5… More >

    Melatonin and its protective role against male reproductive toxicity induced by heavy metals, environmental pollutants, and chemotherapy: A review


    BIOCELL, Vol.44, No.4, pp. 479-485, 2020, DOI:10.32604/biocell.2020.011675

    Abstract Melatonin, as a ubiquitous indoleamine hormone, is synthesized primarily by the pineal gland. It has diverse biological effects through quite complex mechanisms. More recently, studies have focused on the mechanism of melatonin in anti-reproductive toxicity/damage. Since melatonin possesses strong antioxidant and anti-apoptotic properties, researchers have examined its potential role in protecting against male reproductive toxicity/damage, which may be induced by chemotherapy or environmental toxicants and can lead to male infertility. In this article, recent progress regarding the protective effects of melatonin on male reproductive toxicity/damage is reviewed. More >

    Stress Ameliorative Effects of Indole Acetic Acid on Hordeum vulgare L. Seedlings Subjected to Zinc Toxicity

    Monika Sood1, Shanti S. Sharma1, Joginder Singh1, Ram Prasad2,3,*, Dhriti Kapoor1,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.1, pp. 71-86, 2020, DOI:10.32604/phyton.2020.07180

    Abstract The heavy metals present in the environment accumulate in the plants and affect their productivity and yield. By entering the food chain, metals cause several serious health problems in human beings as well as in other organisms. Indole acetic acid (IAA) is known to act as a signaling molecule between symbiotic association of metal accumulating plants and plant growth promoting rhizobacteria (PGPR). Present study demonstrated a protective role of IAA against surplus Zinc (Zn)-induced toxicity to Hordeum vulgare seedlings. Elevated Zn concentrations suppressed the plant growth, caused a reduction in leaf relative water contents (RWC) and elevated free proline and… More >

    The effects of tin (Sn) additions on the growth of spinach plants

    Müller FL1,2, LF Cyster1, LM Raitt1, J Aalbers1

    Phyton-International Journal of Experimental Botany, Vol.84, No.2, pp. 461-465, 2015, DOI:10.32604/phyton.2015.84.461

    Abstract An increase in bioavailable tin in the environment could result in bioaccumulation thereof in agricultural crops, and therefore, have adverse health consequences on humans that eat these crops. The aims of the current study were thus to assess the uptake of Sn by spinach plants, and the subsequent effects this will have on the uptake of Na, Zn, K, Ca, and Mg as well as the growth of spinach plants. Spinach plants were grown in sand culture and received tin at concentrations of 0.02, 0.2, 2 and 20 mg/L along with a nutrient solution. The uptake of tin at detectible… More >

    Effects of nitrogen fertilization on heavy metal content of corn grains

    Rui Yu-kui, Zhang Fu-suo, Shen Jian-bo

    Phyton-International Journal of Experimental Botany, Vol.78, pp. 101-104, 2009, DOI:10.32604/phyton.2009.78.101

    Abstract Nitrogen fertilization has played a significant role in increasing crop yield, and solving problems of hunger and malnutrition worldwide. However, excessive nitrogen inputs do not significantly increase crop yields but may lead to many serious environmental problems. The effects of nitrogen fertilization rate were studied on heavy metal content of corn grains. Our results show that nitrogen fertilization management is beneficial for reducing production costs, protecting the environment, and improving the quality of farm products. More >

    Heavy metal accumulation in Pelargonium hortorum: Effects on growth and development

    Orroño DI, RS Lavado*

    Phyton-International Journal of Experimental Botany, Vol.78, pp. 75-82, 2009, DOI:10.32604/phyton.2009.78.075

    Abstract Ornamental plants have been proposed for growing in heavy metal (HM) contaminated soils, and also for phytoremediation. We evaluated (1) biomass production and (2) HM accumulation in Pelargonium hortorum. Plants were grown for 16 weeks on HM (cadmium, chromium, copper, lead, nickel and zinc) enriched soils. Treatments were i) control, non-enriched soil, ii) medium concentration treatment, and iii) high concentration treatment. Four destructive harvests were carried out, and roots, stems, leaves, and flowers were analyzed each time. Concentrations of HM were determined using ICP. Significant reductions in biomass production were observed in HM-enriched soils compared with the control. Different indexes… More >

    Adverse effects induced by chromium VI, cadmium and arsenic exposure on hypothalamus-pituitary physiology

    Jimena P. CABILLA, Sonia A. RONCHETTI, Beatriz H. DUVILANSKI*

    BIOCELL, Vol.40, No.1, pp. 15-18, 2016, DOI:10.32604/biocell.2016.40.015

    Abstract Environmental contamination with some metalloids and heavy metals (M/HM) raises concern due to well known adverse effects on health. Among these pollutants, chromium VI (Cr VI), cadmium (Cd) and arsenic (As) are frequently present as a result of natural sources or due to industrial activities. They are able to easily enter the organism and negatively affect many organs and systems. In vivo (exposure to Cr VI, Cd or As through drinking water) and in vitro experiments (primary pituitary cell cultures) were performed in male Wistar rats to address their actions on hypothalamus-pituitary axis. All the M/HM accumulated in hypothalamus and… More >
