Abstract

Soil treated with different concentrations of copper (75, 160, and 190 mg/kg soil) and cadmium (4, 8, and 10 mg/kg soil) had assessments for their effects on the growth of algae (Cladophora and Spirogyra). Soil treated with copper (190 mg/kg) and cadmium (10 mg/kg) has shown a significant impact, decreasing the dry weight of Cladophora (1.600 and 0.353 mg) and Spirogyra (1.500 and 0.189 mg). Chlorophyll a and b content also expressed decreased with copper application to the soil at 190 mg/kg. Cladophora and Spirogyra algae had concentrations of 0.082 and 0.007 mg/g fresh weight, respectively. In algae Cladophora, the cadmium (10 mg/kg soil) levels reached 0.073 and 0.008 mg/g of fresh weight, while Spirogyra had concentrations of 0.013 and 0.011 mg/g. In the nutrient concentration status of cladophora, soil treatment with cadmium (10 mg/kg) was the most beneficial for phosphorus, chloride, and sodium levels (0.170, 0.010, and 0.010 mg/g, respectively). Similarly, the phosphorus and sodium concentrations had declined with copper treatments in algae spirogyra (0.150 and 0.040 mg/g, respectively), while chloride concentration reduction was by cadmium (10 mg/kg soil).

重金属处理对藻类叶绿素a、b和矿质元素浓度的影响
用不同浓度的铜(75、160和190 mg/kg土壤)和镉(4、8和10 mg/kg土壤)处理的土壤评估了它们对藻类(枝藻和Spirogyra)生长的影响。用铜(190 mg/kg)和镉(10 mg/kg)处理的土壤显示出显著的影响,降低了枝藻(1.600和0.353 mg)和Spirogyra(1.500和0.189 mg)的干重。叶绿素a和b含量也随着向土壤施用190 mg/kg的铜而降低。枝藻和Spirogyra藻类的浓度分别为0.082和0.007mg/g鲜重。在藻类枝藻中,镉(10 mg/kg土壤)含量分别达到0.073和0.008 mg/g鲜重,而Spirogyra的浓度分别为0.013和0.011 mg/g。在枝藻的养分浓度状态下,用镉(10 mg/kg)处理土壤对磷、氯和钠水平(分别为0.170、0.010和0.010 mg/g)最有利。同样,藻类螺体中的磷和钠浓度随着铜处理而下降(分别为0.150和0.040 mg/g),而氯化物浓度则因镉处理而降低(10 mg/kg土壤)。

期刊介绍: The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO). Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society. The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards. The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
