ABSTRACT
The purpose of this paper is to analyze the main characteristics of the crowns of poplar that grows in different conditions. Thus, were studied 124 black poplar trees (Populus nigra L.) located in alignment and 124 white poplar trees (Populus alba L.) in the forest. The measured elements in the field (the stem diameter, the total height of the tree, the height of crown base and four rays of the crown) have been interpreted in such a way as to be able to determine the influence thereof on the crown-projection area. Following the interpretation of the results it appears that, in addition to the stem diameter, the conditions where the trees grow, plays a crucial role in the development of the crown.

Keywords: crown-projection area, the rays of the crown, height of the crown base
