Popis:	Rootstocks (Piceaabies (L.) Karst.) and scions (Piceapungens Engelm.) were labelled separately during graft union development with 14CO2 and translocation of the labelled photosynthate determined qualitatively and quantitatively. Rootstock photosynthates did not cross the graft union after scion budbreak had started. Total recovery of labelled scion photosynthates in scions declined from nearly 60% to less than 10% during the 1st week after grafting, and did not increase until xylem connections were established 1-2 weeks before budbreak. Less than 2% of the recovery from the scion was found in the graft union before scion budbreak. Most of the label recovered before scion budbreak was in the needle sugar fraction. After budbreak, most of the label was recovered in elongating buds.
