Popis:	The influence of a new micrografting method in vitro was tested by using long shoot meristems of adult 140 year old European larch trees grafted onto larch seedling rootstocks in sterile peat pellets. Five months after grafting and transfer of grafts to ex vitro conditions, new shoots from sprouting scions were re-established into tissue culture. The propagation behavior of shoots derived from these explants was compared with shoots established via bud culture from the same donor trees. Shoot explants from micrografts multiplied more rapidly than shoots explants from the original adult donor trees. Rooting experiments with cuttings from six micrografted clones resulted in 49.9 ± 11.9% rooting. Cuttings from donor trees invariably showed no root formation. The results confirm a rejuvenating influence of micrografting in larch.
