Having no importance for Romanian forestry, Picea pungens Engelm. is a very ornamental species, often seen in Romanian parks and gardens. They are cultivated especially glauca and argentea forms). The biggest problem of this forms is getting seedlings. The generative way is not recommended because, although at begin those specimens obtained have the characteristic color of the variety, with the passage of time the color disappears. So, the vegetative way remains the only possible way in order to obtain best specimens. Propagation method used in these experiments is side-veener- grafting. The rootstock was represented by Picea abies, which was grafted with scion collected from Picea pungens Argentea variety. The experiment factors were vegetative stage of rootstock and grafting level. Regarding the first factor, we chose two graduations, the grafting being made on less active rootstock and well active rootstock. Regarding the grafting level, the graft was made to the first growth, on the second and on the third growth. The behavior of grafted seedlings was followed throughout the growing season, with the work of care applied in the process, but the final inventory of survivinng grafts was made at the end of the growing season. To interpret the results on grafting efficiency, expressed by number of slips caught, the data obtained from the measurements were statistically processed by variance analysis method, using the method of multiple comparisons (the Duncan test).
