In this investigation, the effect of seed source on the germination and survival of Acer velutinum Boiss. was assessed. Seeds were collected from 11 seed sources ( located at 20 to 2200 meter a.s.l in Mazandaran forests) and planted in a mountain nursery (Orimelk located at 1550 meter a.s.l) as completely randomized block design with three replications. The results show that the effect of seed source on germination and survival was statistically significant (p<0.01). Germination and survival rates were lower for the Pasands, Ashak and Deis sources, and the maximum seed germination was related to Lamzer site. Effect of seed sources on survival of seedling was significant too. The maximum and minimum survival was related to Lajim and Ashak, respectively. Regarding plan table seedling, the effect of seed source was significant. The maximum efficiency of seedlings has been found in Lajim, Lamzer, Parke Noor and Sangdeh sites, while the minimum range of efficiency was related to Ashak and Pasand2.
