Abstract

Many projects have been implemented with the aim of increasing production per unit area and selecting clones with high wood production and compatible to edaphic and climatic conditions of Markazi province. The production of common clones planted in the Markazi province is estimated to be 10-15 m3/ha/year, which is much lower than the country's average, 20-25 m3/ha/year. Poplar research has begun since 1993 by collecting and identifying native and non-native cultivars. The compatibility project was implemented with 35 clones for 10 years in 1997 and the clone P.n.56/72 with a production of 36.55 m3/ha/year was identified as the best clone. In order to study this process, the second phase of this project was carried out with the aim of investigating the effect of cutting operation on the production of different clones compared to the previous period. The results of a seven-year study showed that clone P.n.56/72 with an average production of 27.33 m3/ha/year had a significant difference with other clones, and clone P.n.betulifolia with an average production of 18.03 m3/ha/year had good condition and was introduced as a successful clone. Also, the second stage of compatibility was conducted with the aim of investigating the wood production of other clones in Arak. The results showed that clone P.n.62/154 had a significant difference with other clones with an average production of 33.21 m3/ha/year and was the most successful clone in Markazi province, which is recommended for cultivation in the prone areas of province.
