    EFFECT OF ABIOTIC ENVIRONMENT ON PINUS SYLVESTRIS HEIGHT GROWTH:A CASE STUDY AT THE NORTH-EASTERN BLACK SEA REGION

    Zafer ÖLMEZ1 and Zafer ASLAN2

    The predicted rate of global warming and changes in precipitation patterns will strongly effect forest and ecosystems. Global climate modelling shows that with global warming on an annual average there will be a negative trend at middle latitudes. To define the abiotic environment effect, a set of average monthly temperature, precipitation and relative humidity observed at a nearby weather station was considered. In this paper some climatological parameters recorded in Artvin (41° 10' N, 41° 49' E) and Ardanuç (41° 10' N, 41° 03' E) between 1950 and 1996 have been statistically analysed. This study has been carried on a pilot area of 200 ha in Ardanuç (Artvin) covered with Pinus sylvestris. Height growth of trees has been measured for the sample area. Some results of single and multiple regression analysis amongst height growth and climatological parameters are presented. Air temperature variation plays an important role on the growing rate. It is inversely proportional to variations in relative humidity and precipitation.

    Keywords: Pinus sylvestris, height growth and meteorological parameters
