Planting Ulmus pumila L. in Mid-Autumn: How Many Cuttings of Siberian Elm and What Types Can We Get for Rooting and Nursery Production
摘要：The study of the vegetative multiplication of 5 clones of Ulmus pumila is carried out under conditions of a plant-producing nursery. The plantation was made in mid-autumn. The objective is to know the quantity of cuttings of length of 25 cm and their characteristics（basal diameter） obtained based on the new annual growth in 5 different clones. All the material obtained by each clone is cut and classified by basal diameter into 21 categories（< 2 mm to 25-30 mm）. Survival rates of clones in October of the following year varied between 31%, 36%, 55%, 65% and 87%.
