Abstract

Abstract. Sukmarani D, Proklamasiningsih E, Susanto AH, Ardli ER, SudianaE, Yani E. 2021. Superoxide dismutase (SOD) activity of Ceriops zippelianaBlume in Segara Anakan Cilacap (Indonesia) under heavy metal accumulation. Biodiversitas 22:5627-5635. Ceriops zippeliana Blumeis a true mangrove species that occupy habitats exposed to environmental stress, such as salinity and heavy metal contamination, which is the case in Segara Anakan Cilacap, Central Java. Both salinity and heavy metal stress can lead to the production of reactive oxygen species (ROS), which can be detrimental to plants if they are present in excess. Plants have defense mechanisms to prevent excessive ROS, one of which is by the use of superoxide dismutase (SOD) enzyme. This study aims to explain the accumulation of heavy metals (Pb, Cd, Cu, and Zn) in C. zippeliana as well as the translocation of the metals. In addition, the correlation between heavy metal concentrations and SOD activity in C. zippeliana is reported. Plant samples were randomly collected from Segara Anakan, Cilacap. The analysis was conducted using the bio-concentration factor (BCF), translocation factor (TF), and linear regression in the SPSS program. It was found that Pb, Cu, and Zn levels in Segara Anakan Cilacap sediments were still within acceptable limits, while Cd level was moderately polluting. Metal accumulation was higher in the branches of C. zippeliana compared to those in roots and leaves. The SOD activity of C. zippeliana in Segara Anakan is seemingly not related to metal contents in plant parts.

Effects of Combined Stresses of Salinity (NaCl) and Heavy Metal (NiCl2) Levels on Seed Germination and Growth of Citrullus colocynthis l.

“…The minerals and heavy metals accumulation in the plant cells may lead to negative effects like ion toxicity induced mainly by salinity and drought stress (Kumar, 2020). Detaining absorbable water by seeds due to salinity and heavy metal stress can lead to reduced germination (Sukmarani et al, 2021). Decreased seed germination under salinity and heavy metal stress may be illuminated by turgor pressure limitation or dry material storage (Khosropour et al, 2022).…”

RESPONSE OF Citrullus colocynthis L. TO SINGLE AND COMBINED STRESSES OF SALINITY (NaCl) AND HEAVY METAL (NiCl 2 )

“…The minerals and heavy metals accumulation in the plant cells may lead to negative effects like ion toxicity induced mainly by salinity and drought stress (Kumar, 2020). Detaining absorbable water by seeds due to salinity and heavy metal stress can lead to reduced germination (Sukmarani et al, 2021) Decreased seed germination under salinity and heavy metal stress may be illuminated by turgor pressure limitation or the dry material storage (Khosropour et al, 2022). High levels of salinity suppress seedling growth, imposing a negative impact of NaCl on cellular membranes, and destructing cytoplasmic membranes due to ion toxicity (Shehzad et al, 2019;Shahid et al, 2020).…”
