Optimization of nursery procedures is important part of introduction of white poplar genotypes in common practice. In this case we examined reaction of three genotypes of white poplar (Populus alba L.) on term of cutting preparation and slope aspect by survival and growth of rooted cuttings in PE "Vojvodinašume" nursery "Ratno ostrvo", near Novi Sad. There were two treatments concerning term of cuttings’ preparation: a) middle of March (cuttings were stored in cool chamber at 2±1°C) and b) the day before planting at the first half of April. Also, there were examined the effect of slope aspect of nursery area: a) East-northeast, and b) West- southwest facing slope. Gained results suggest better survival and growth of rooted cuttings made at the middle of March and better survival and growth on area oriented to the West-southwest. The gained effects were mostly consistent for all examined genotypes (better results on West-southwest aspect and after early term of preparation). These results suggest that the research on the influence of terms of cuttings’ production and the slope aspect could be important issues in creation and optimization of nursery technology suitable to the specificities of white poplar clones.
