This research aims to analyze the concentration of Cu, Zn, and pH in mining wastewater at Pit Osela PT J Resources Bolaang Mongondow (JRBM) effect absorption water hyacinth (eichhornia c) lettuce (pistia stratiotes) on heavy metals Zn plant tissues. Research Methods: The study was located JRBM's greenhouse Regency with Mining Wastewater (ALP) (mining). results: Cu ALP initial condition 15.59 mg...

The chromosome number and karyotype formula of interesting five genera six species Araceae from Thailand were studied, including Lasia spinosa —uncommon local Thai vegetable (2n=26, L6sm+L2st+Mm14+M4sm), Pistia stratiotes—common aquatic plant (2n=28, Lm10+Mm18), Pycnosphata palmata—rare endemic to Laos Lm12+L4sm+M6m+M2sm+M2st), Scittomaglottis calyptrata—rare in Lm6+L2sm+Mm6+Msm12), Typhonium g...

Prevalence of various aquatic vegetation and their role in supporting vector breeding were studied by drawing plant samples from natural fresh water habitats in Shertallai region which is endemic for Brugia malayi. As many as 30 aquatic plant species were identified in addition to the most abundant and preferred host plants such as Pistia stratiotes, Salvinia molesta and Eichhornia crassipes wh...

Larvae and pupae of the genus Mansonia Blanchard attach to the roots of aquatic plants by means of modified structures to obtain oxygen. A study of the association of larval Ma. indubitans and Ma. titillans with floating macrophytes was conducted at Macies Pond, Argentina. Fifty-four sampling units were taken from January to May 2003. Three genera of host plants were considered: Pistia, Limnobi...

The paper covers the research of copper and zinc nanoparticle effect on the content of ascorbic acid, and quantitative and qualitative composition of amino acids and acylcarnitines in Pistia stratiotes L. plants. Plant exposition to copper nanoparticles led to the decrease in (1) the amount of ascorbic acid, (2) the total content of amino acids (by 25 %), and (3) the amount of all studied amino...
