| Abstract | The influence of pollution stress (SO$_{2}$, Cu$^{2+}$, Pb$^{2+}$, Zn$^{2+}$ and fluoride) on composition changes in cellular membranes of roots of three European of Scots pine (Pinus sylvestris L.) populations were examined. Plant material growing in three experimental areas: Kórnik relatively free of air pollution (control), Luboń: SO$_{2}$ and HF and Głogów: SO$_{2}$ and heavy metals. Analysis of total phospholipids and their composition indicates that the phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were present in lower concentration in the root tissues from both polluted sites (Luboń and Głogów). The difference in PC:PE ratio between control and both polluted sites was greater in root of Scots pine population from Russia than in the population from Slovakia. Under pollution conditions the content of lipid soluble antioxidant α-tocopherol was lower about 220 %, in comparison to the control. The action of pollution stress also lead to lowering of unsaturated:saturated ratio of total fatty acid, and lower content of polyunsaturated fatty acids, linoleic acid (18:2) and eicosatrienoic acid (20:3). We concluded that the long-term pollution stress markedly inhibited lipid biosynthesis in root tissue of Scots pine and it is probably contribute to the reduction of productivity of forests. These results also suggest that lipid composition can be used as an indicator of changes in tissue roots of Scots pine caused by air and/or soil long-term pollution. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
