Title

Evaluation of adaptation and performance of industrial Eucalyptus species provenance in Qom wastewater station

Pages

Abstract

 Background and Objectives: Eucalyptus species are used for afforestation in different ecological areas due to their rapid growth and high genetic diversity. This study was done to evaluate performance of some species and provenances of Eucalyptus during a 3-year period in Wastewater Station in northeast of Qom. Materials and Methods: The experiment was a factorial experiment based on randomized complete block design (RCBD) with two factors: 1) genotype at 6 levels and 2) time at 3 levels in four replications on 5-year-old Eucalyptus saplings. Irrigation was carried out using the treated Wastewater of Qom city. Selected genotypes were including six provenances of Eucalyptus camaldulensis Dehnh., E. microtheca Muell. and E. rubida Deane & Maiden. Growth traits including: tree height, Trunk diameter at 30 cm height, height growth, diameter growth and height to diameter ratio were measured. Statistical analysis such as ANOVA and comparison of mean was done among selected genotypes and different years and finally adaptation and growth performance under experimental conditions have been introduced. Results: The results showed that the effect of treatment (species and provenances), replication, interactions between treatment and replication, and year on tree height were significant. Mean comparisons showed that species and provenances were classified into five distinct groups and one common group; E. camaldulensis 41ch was in the highest group. Trees were grouped in 4 groups based on the diameter of trunk, E. camaldulensis 41ch and E. camaldulensis Qom were in the first and second groups. In addition based on height growth E. camaldulensis 41ch and E. camaldulensis Qom were in the first group and E. microtheca 62 and E. rubida 166sh were in the last groups. Based on the Trunk diameter growth E. camaldulensis Qom was in the first group and E. rubida 166sh was in the last group. In terms of trunk height to diameter ratio, the species were divided into two distinct and three common groups, based on these results E. camaldulensis 41zh with the highest height to diameter ratio was in the first group. Conclusion: In general, the results showed that E. camaldulensis 41ch had the highest amount of diameter and height. E. camaldulensis 41ch seems to have a higher performance for industrial wood production than other species and provenances. E. camaldulensis Qom was also ranked first in terms of diameter and height growth, this seems to be due to seed origin (Qom) and adaptation to regional conditions. Overall, the results showed that E. camaldulensis had the highest rank in height and diameter growth, followed by E. microtheca.
