Determination of the accumulator plants in Kucukcekmece Lake (Istanbul)
(Academic Journals, 2010) Sahmurova, Aida; Celik, Mucella; Allahverdiyev, Surhay
Soils are polluted by actions like using commercial fertilizers, pesticides, soil regulators and hormones to increase the amount and quality of agricultural production, discharge of soil and liquid wastes, performing wastewater sludge applications, using polluted waters in agricultural irrigation, atmospheric precipitations and radioactive sprays. It is an important environmental problem to reform and clean the soils polluted with heavy metals. Phytoremediation is a measure which uses several plants to remove the pollutants from water and soil to reduce, completely extract, control or immobilize them. The plants used for this reason are referred to as the accumulators. Metal accumulation can occur in several different families like small annual grass to perennial bushes and trees. For remediation or cleaning of the soils polluted with heavy metals, the ideal plant species are the ones which can produce high amounts of biomass, and can accumulate and tolerate the pollutants. In this study, the Cd and Zn contents obtained from Kucukcekmece Lake border were monitored on monthly basis and it was aimed at determining the plant species with accumulation ability. The plants chosen for this activity were Labiatae galatica, Compositae cardueae, Cypereace carex, and Phragmites australis. Compositae cardueae was the most efficient species in terms of mean heavy metal intake performance.

Response of photosystem II and photosyntheticpigments to salt and Baikal EM1 in tree seedlings
(Academic Journals, 2011) Allahverdiyev, Surhay; Atilla, Atik; Ismail, Bayazit Sah; Sahmurova, Aida
The aim of the present research is to determine the effect of Baikal-EM1 preparation on photosystem II (PS II) activity and the synthesis of chlorophylls by tree seedlings in conditions of salt stress. This work reports, for the first time, the investigation of the influence of a preparation of effective microorganisms on the activity of PS II and the chlorophylls in the leaves of Gleditschia triacanthos L. and Abies nordmanniana Karst in conditions of salt stress. The methods used for the analyses of the structural components of these species allow the estimation of the condition of PS II and chlorophylls in normal plants and those that are subjected to salt stress. The analytical methods can also be used for diagnosing the resistance of plants to the action of salts. The results showed that salt stress appears to inhibit the activity of PS II and the synthesis of chlorophylls. The use of Baikal EM1 in both kinds of tree seedlings reduced the inhibiting effects of NaCl. The results obtained are a positive contribution to the effort to improve the salt resistance of seedlings, in that they increased our understanding of plants' resistance to the action of salts and identified an approach that increased the adaptive potential of the plants.
