| Abstract | ||
| In order to access the most suitable poplar clones for the purpose of expanding wood farming activities in the lowland areas of Guilan province, twelve different poplar clones from euramericana, deltoides and hybrid poplars were studied in nursery (annual seedlings) and poplar plantation (three-year-old trees). This study was carried out in a Randomized Complete Block Design with three replications at Fakhr Abad research station in 2019. Survival percentage, diameter and height of one-year-old seedlings in nursery as well as survival percentage, diameter at breast height and height of three-year-old trees in poplar plantation were measured at the end of the growing season. Analysis of variance of data obtained from survival percentage, diameter and height of different studied poplar clones showed that there was no significant difference between survival rate of three-year-old trees and diameter of one-year-old seedlings, but there was a significant difference between survival rate and height of one-year-old seedlings and diameter and height of three-year-old trees. Thus P. deltoides Marquette, P. deltoides 92/258, P.eur. Blanc de poitou and P. deltoides 92/160 clones in a group with the highest and P. x. 87m.119 had the lowest survival rate, and P. deltoides Marquette and P. deltoides 92/258 clones had the highest and lowest height growth in nursery, respectively. Also, the study of diameter at breast height and height of three-year-old trees showed that P. deltoides 92/258 and P.eur. I-Sieres had the highest and the lowest diameters, respectively. P.eur. Blanc de poitou clone was not competitive with other clones in height. | ||
