Using Morphological Traits for Identification of Poplar (Populus alba) Stands in Iran (Esfahan and Zanjan Provinces)

Genetic diversity is important for long time survival of poplar cultivations and will increase their adaptation against environment changes. Therefore, in order to adopt strategies for conservation and development, it is necessary to estimate the amount and distribution of genetic diversity in existing populations of poplar. In this study, for estimating genetic diversity between and within 7 stands of Populus alba established in Esfehan and Zanjan provinces, morphological traits were measured. In order to assimilate environmental conditions, cuttings were planted under randomized complete blocks design with 3 replications. In the middle of growing season, 17 morphological traits were measured and data were analyzed using analysis of variance, t-test and cluster. Results showed significant differences observed between stands. By using cluster analysis, stands were classified in 2 groups on the base of 2 different provinces. Results showed that in homogeneous conditions, morphological traits could reveal diversity and similarity in poplar stands.
