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).
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.
