title: Height growth of different European Scots pine Pinus sylvestris L. Provenances in a heavily polluted and a control environment.
abstract: Results are presented of height measurements and degree of needle injury on five-year-old plants of Scots pine (Pinus sylvestris L.) growing near a phosphate fertiliser plant that emits SO(2) and fluorides. The populations of Scots pine represented in this experiment originate from 11 countries and were substantially differentiated in height growth and extent of needle necroses. Those populations which grew most rapidly were found to be the most sensitive to pollutant injury. The least productive provenances from the north of the range (Sweden, USSR) are at the same time characterized by lowest decline in height growth, lowest mortality and least extensive necroses. It is proposed that gene banks be established for the best genotypes likely to be eliminated in the heavily polluted conditions of Poland today.
