This investigation was carried out to study the effect of provenance variation on early growth and biomass of Caucasian maple (Acer velutinum Boiss.) seedling. The seeds were collected from four different seed sources, altitudes of 400, 1000, 1600 and 2200 m a.s.l. in forests of Sari region (north of Iran). Seeds were sown at a randomized completely block design (with three replicates) in the Ourimelk nursery (h = 1600 m). The results of the first growing period displayed that stem length, stem biomass, leaf biomass and total biomass of seedlings, produced from different altitudes seeds, were significantly different, whereas these terms were bigger in lower elevations (400 and 1000 m). Root length and root biomass of seedlings were not statistically different. The general results of this examination suggest that in order to obtain the greater aboveground biomass of Caucasian maple seedling in Ourimelk nursery, it is better to use the seeds of middle elevations (1000 m) in years that seed production of the local forest (1600 m a.s.l.) is inadequate.
