Abstract

Given that the characteristic of free loating plants to uptake metals can have a positive efect on the eiciency of the remediation process of a wetland, it is important to investigate the factors that may impact the process of uptake of metals by the plants. By conducting this present study over a short duration of time, the efects of salinity on the growth, the content of the photosynthetic pigments (chlorophyll a, b, and carotenoid), and heavy metal uptake by Spirodela polyrrhiza were investigated. It was also observed that at a high level of salinity (100 and 200 mM NaCl) the relative growth rate (RGR) of the plant decreased. Especially, at a salinity level of 100 mM NaCl, the RGR values were noted to become negative. he content of photosynthetic pigment was negatively correlated with the salt level. Additionally, a high level of salinity was observed to cause a decrease in the accumulation of the metals cadmium (Cd) and nickel (Ni) by S. polyrrhiza.

Özet

Serbest yüzen bitkilerin karakteristik metal alabilme özelliği sulak alanların temizlenmesi üzerine pozitif etkili olabilir ki buda bitkiler tarafından metallerin alınımında etkili olan faktörlerin belirlenmesinde önemlidir. Kısa süreli bu çalışma ile, Spirodela polyrrhiza’da tuzluluğun büyümeye, fotosentetik pigment içeriğine (Kloroil a,b, ve karetoneid) ve ağır metal alınımı üzerine etkisi incelenmiştir. Yüksek tuzluluk düzeyinde (100 ve 200 mM NaCl) bitkideki doğrusal büyüme oranının (RGR) azaldığı gözlenmiştir. Özellikle, 100 mM NaCl düzeyinde, RGR değerlerinin negatife gittiği not edilmiştir. Fotosentetik pigment içeriği tuz düzeyi ile negatif ilişkilidir. Bununla birlikte S. polyrrhiza’da yüksek tuz düzeyinin, kadmiyum ve nikel birikiminin azalmasına neden olduğu gözlenmiştir.
