Abstract
Bench grafting followed by forcing was studied in Quercus robur L. 'Fastigiata' (1997-99), as well as Quercus pontica L. and Quercus x turneri Willd. 'Pseudoturneri' (Schneid.) Henry (1999). Two-year old bare-rooted seedlings of Quercus robur were used as rootstocks. They were lifted in the late autumn and cold-stored until grafting time. Scions were collected before grafting and were cut into segments with two to three buds. Bench grafts were made by hand without any tying in February and March in 1997, 1998 and 1999. The grafts were forced for 2 to 3 weeks at 26-27° C and in condition of high relative humidity (80-90 %) to induce callus formation. Then the grafts were stored at 2 to 3° C until planted into 10-12 l containers in an unheated greenhouse or in the filed at the end of April.The best result with Quercus robur 'Fastigiata' (96 %) was obtained in 1999, and the survival rate after one year was about 80 % except for outdoor planted plants, which reached only 30 % survival. The graft take of Quercus x turneri 'Pseudoturneri' was 85 %, and the graft takes of Quercus pontica were 92,5 %. They were planted into containers in a greenhouse. The survival rate of these plants after one year was about 78 %.

Key words: grafting, propagation, oak, Quercus robur, Quercus x turneri, Quercus pontica, vegetative propagation.
