This problem is prevalent in the Central Asian countries as well. A viable solution for this and further environmental issues would be the cultivation of a fast-growing tree species, such as poplar. Several poplar cultivars were tested on plots in Almaty, Bishkek and Khorog. The performance of the trees was assessed by investigating growth in terms of height and diameter, death rate, being bent down, pest infestation, and phenology. The influence of environmental conditions and the influence of genotype were discussed. Both factors significantly influenced height, diameter at breast height and Death Rate. For basal diameter and diameter in 2m height, the location was the single influencing variable. For characteristic of being bent down, cultivar was the single influencing variable. For the percentage of trees that were infested by pest as well as for the extend of pest infestation none of the factors were seen as having an influence. Even though there are some bio-physical and socio-economic constraints, there are many opportunities for the cultivation of poplars in Central Asia.}, language = {en} }
