This study was carried out to investigate the relationship between climate condition (temperature and precipitation) and tree-ring widths of Acer velutinum in north of Iran. A total of 13 cores from 4 trees in same site were selected to measure tree-ring. To determine the response to the climate, correlation coefficients between tree-ring widths and climate data were calculated using biological years from October of the previous year to September of the current year (by Pearson's correlation and forward stepwise). Pearson's results showed that the temperature (mean, maximum and minimum) hadn't significant effect on tree ring widths, while there is a positive relationship between monthly precipitation of August and tree-ring widths. Forward stepwise results indicated that the tree-ring width values were related to precipitation of August (57.2%) and minimum monthly temperature of March (10.8%).

A total of 13 cores from 4 trees in same site were selected to measure tree-ring. To determine the response to the climate, correlation coefficients between tree-ring widths and climate data were calculated using biological years from October of the previous year to September of the current year (by Pearson's correlation and forward stepwise). Pearson's results showed that the temperature (mean, maximum and minimum) hadn't significant effect on tree ring widths, while there is a positive relationship between monthly precipitation of August and tree-ring widths. Forward stepwise results indicated that the tree-ring width values were related to precipitation of August (57.2%) and minimum monthly temperature of March (10.8%).
