Pysiological effects of NaCl on Ceratophyllum demersum L., a submerged rootless aquatic macrophyte
In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated on Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn contents of macrophyte tissues increased.

متن کاملSpeciation and distribution of arsenic in the nonhyperaccumulator macrophyte Ceratophyllum demersum.
Although arsenic (As) is a common pollutant worldwide, many questions about As metabolism in nonhyperaccumulator plants remain. Concentration- and tissue-dependent speciation and distribution of As was analyzed in the aquatic plant Ceratophyllum demersum to understand As metabolism in nonhyperaccumulator plants. Speciation was analyzed chromatographically (high-performance liquid chromatography...
متن کاملArsenic accumulation and speciation in the submerged macrophyte Ceratophyllum demersum L.
INTRODUCTION Ceratophyllum demersum L. is a widespread submerged macrophyte in aquatic environments. METHODS Simulation experiments were conducted in the laboratory to investigate arsenic (As) accumulation, speciation, and efflux of C. demersum exposed to arsenate and arsenite solutions. RESULTS Plant shoots showed a significant accumulation of As with a maximum of 862 and 963 μg As g(-1) d...
متن کاملthe effects of multiple intelligences (focus on musical, visual, and linguistic) and direct instruction on learning grammar: a case on iranian efl students at elementary level
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
