Abstract

Interpopulation and intrapopulation variability of three morphological needle traits (length, width and thickness) was investigated in 16 natural silver fir populations in the Balkan Peninsula. The populations represent refugial areas of silver fir (Abies alba Mill.). This paper aims to provide a comprehensive analysis of the influence of climatic factors (mean annual temperature, number of days with temperatures < 0, > 5, < 18, > 18oC, Hargreaves climatic moisture deficit and De Martonne aridity index, on the pattern of morphological needle traits within each population. Populations showed variation in the analyzed morphological needle traits, which could not be clearly defined by any of the analyzed climatic factors. The De Martonne aridity index and Hargreaves climatic moisture deficit had the greatest impact on the trait values, whereas the mean annual precipitation had the lowest. Evolutionary ecology research of the silver fir needle morphology is a valuable contribution to the comprehention of the present genetic variability as a prerequisite for adaptation to the rapid climate change and conservation of the species area in the Balkan Peninsula region.

巴尔干地区食物种群（Abies alba Mill）形态特征的空间变异性污染与气候因素的比较

研究了巴尔干半岛16个天然银杉种群针叶长度、宽度和厚度3个形态性状的种群间和种群内变异。这些种群代表了银冷杉(Abies alba Mill.)的避难所。本文旨在综合分析年平均气温、气温< 0、< 5、< 18、< 18℃的日数、Hargreaves气候水分亏缺和De marton干旱指数等气候因子对各种群形态针状性状格局的影响。不同种群在针叶形态性状上存在差异，这种差异不能用任何气候因子来明确界定。De Martonne干旱指数和Hargreaves气候水分亏缺对性状值的影响最大，而年平均降水量对性状值的影响最小。对银杉针叶形态的进化生态学研究，对了解银杉当前的遗传变异具有重要意义，是适应快速气候变化和保护巴尔干半岛地区物种的先决条件。
