Abstract


Acer (Sapindaceae) is a genus with 10 species in Iran. These plants are of economic, ornamental and medicinal importance. Totally 37 populations of seven Acer species as Acer velutinum, A. monspessullanum, A. platanoides, A. campestre, A. cappadocicum, A. negundo and A. palmatum distributed in different parts of Iran were studied in this project. In order to study the morphological variation 13 quantitative and 25 qualitative features were used. Multivariate statistical analysis was done by use of SPSS Statistical software. Factor analysis revealed that more than 44% of total observed variation is dealt with width of fruit wing, leaf width, length of fruit wing, petiole length, length of fruit wing and leaf length. In second factor peduncle and samara length are of diagnostic importance in studied species. Species relationships were evaluated by use of cluster analysis and ordination based on principal component analysis. Morphological features showed species separation and the close relationship between A. platanoides and A. cappadocicum.
