Abstract
This paper points out the significance of different technological procedures defined by the terms of taking and planting the cuttings in the production of 1/1 plants of two clones of Euramerican poplar (Populus × euramericana (Dode) Guinier): I-214 and Pannonia. The study results indicate that, on soil type sandy fluvisol, the late terms of planting (end of April) have significantly lower survival of rooted cuttings of both study clones, together with unfavourable height structure of rooted cuttings, i.e. insufficient number of plants per hectare. The clone Pannonia has a higher adaptability, i.e. a greater number of the applied technological procedures, defined by the terms of taking and planting the cuttings, results in the satisfactory survival of rooted cuttings, compared to clone I-214. Also, the quality structure of the clone Pannonia planting material is better, thanks to the greater heights of rooted cuttings. The differences of reactions of the two poplar clones on the applied technological procedures, defined by the terms of taking and planting the cuttings, point to the potential adaptation of nursery production to the specificities of the cultivated clones.
