Variability of Diameter Increment of Taxodium ( Taxodium distichum (L.) Rich.) Under the Influence of Climatic Factors in the Area of Backa Palanka in Serbia

Abstract

Background and purpose: Knowledge of the interaction between plant and climatic conditions is of great importance in establishment of new forests, especially in the introduction. Taxodium is an allochthonous species in Europe and this paper presents the data on the success of its introduction and adaptability to site conditions. Material and methods: For the analysis of the climate characteristics in Backa Palanka have been used the data of the Republic Hydrometeorological Service of Serbia for the period 1981-2010 regarding meteorological station Rimski Sancevi. Dendrometric analysis was performed on the dominant trees of Taxodium by taking an increment core at breast height using Pressler drill. On the increment cores was measured diameter increment per each year of the observed period. By the regression analysis was determined the correlation between the diameter increment and climate elements. Results and conclusion: By research of influence of climate factors on the diameter increment of Taxodium trees can be concluded that with increasing of values of mean annual temperature and mean temperature during the growing season comes to a reduction in size of the diameter increment. The increase of the quantity of precipitation over a year, particularly during the growing season, leads to the increase of the diameter increment, and vice versa.
