Germination leads to the development of a seed into a seedling which then develops into two structures: the plumule and radicle. CO2 enrichment for 100 days significantly increased the leaf and total biomass of white spruce seedlings in the high-N regime, RWR of seedlings in the medium-N regime, and root biomass of seedlings in the low-N regime.
