Abstract

The present project was implemented with the aim of identifying the characteristics of local poplar plantations in Markazi province and determining their area, growth and wood production during 2018-2019. , 47 sample plots were selected by random sampling in 6 cities of the province and site characteristics and quantitative and qualitative variables of trees were measured and recorded. For the vegetative variables of trees, 30 trees in each plot were randomly measured and the data were analyzed based on nested design with city factors and poplar plantations within the city and for qualitative traits, their frequency percentage was calculated. 70.21% of poplar plantations in Markazi province were black poplar (Populus nigra L.) and 29.79% were white poplar (P. alba L.). About 63.83% of trees had narrow pyramidal crown, very elongated and elongated, 65.96% of trees had very right and right trunk shape, 82.98% of trees planted through cutting, 72.34% of trees irrigated by flooding, 61.7% of the trees planted in a dense group (stand) and 74.47% of the trees had the main structure (single trunk). The mean annual volume increment of poplar plantations in Markazi province was 29.13 m3ha-1y-1and the mean annual volume increment range of the province was between 4.6 to 74.67 m3/ha due to stands different age and differences among vegetative state. The highest number of trees, plots and poplar plantations area was obtained for Shazand (38064 trees, 19 plots and 156959 m2) and Saveh region was in the second place in terms of these characteristics.
