【 摘 要 】

The average values and variability amplitude of morphological characters and reproductive traits of cones have been determined under the introduction of Pseudotsuga menziesii (Mirb.) Franco trees of different reproduction types. It is shown that the average indicators of the most signs correspond to the control in urban conditions. The level of signs variability is close to control ones, or increased in trees of female and mixed types. The possibility of phenotypic selection of trees of different reproduction types according to their stability in the urban environment is considered, as follows from the variability level of generative sphere parameters.
