  abstract = {Height, basal diameter, diameter at breast height, bud burst, and leaf development were recorded in a 5-year-old hybrid aspen clonal trial. The fi eld trial consisted of four aspen hybrid clones ( Populus tremula × Populus tremuloides ) and one local P. tremula seedling source. Phenological traits were observed in the 3rd year. Growth patterns were recorded during the 3rd and 4th years. Phenological traits were explored in relation to hybrid vigor expressed as growth traits. Differences were observed for phenological and growth traits among hybrid clones and P. tremula . The growth period varied from 143 - 158 days for the four hybrid clones, and was 112 days for P. tremula . The correlation between growth period and yield was highly signi fi cant. The annual growth rate of height for the hybrids was 4.2 cm per 7 days (2.4 for P. tremula ) in the 3rd year and 6.4 cm per 7 days (2.9 for P. tremula ) in the 4th year. After 5 years, mean estimated stem volume of the hybrids was 3.9 times that of P. tremula . Signi fi cant clone by year interaction was observed for height, diameter, and volume growth. The hybrid vigor seems to be mainly attributable to a longer growth period.},
