ABSTRACT
In this study, the capability of the basil (Ocimum basilicum L.) plant as hyper accumulator in
remediation of polluted soils was investigated. The study was carried out as pot trials under controlled
conditions. Increasing concentrations of EDDHA-Fe (0 mgkg-1, 25 mgkg-1, 50 mgkg-1, 150 mgkg-1,
250 mgkg-1) were applied. The basil seedlings germinated in viols were acclimated into pots in
triplicates and harvested 2 months later. The agro-morphological traits, Fe accumulation in plants and
plant nutritional elements were analysed. The basil plant was found to accumulate Fe in its body in
the presence of toxic levels of Fe metal and Fe was found to be antagonistic with micro nutritional
elements. The plant fresh and dry weights and plant height were found to be statistically significant at
50 mgkg-1 EDDHA-Fe application, and beyond this concentration, these values decreased.
The Mg content, which is the central atom in chlorophyll, was found to be the highest at the
mentioned concentration. SPAD values showed a parallel change, too. The basil plant was shown to be
a hyperaccumulator in terms of remediation of the Fe metal, which is both a nutritional element
and a heavy metal. Moreover, Fe fertilization of 50 mgkg-1 was shown to be sufficient for basil
cultivation as a medicinal plant. This result was found to be statistically significant at α = 0.05.
