Preliminary conclusions:- no clear difference between seed orchard and stand
seeds in plant percentage
- great differences within each seed type in plantpercentage (influenced by germination)
- seed lots from seed orchards with northern originand low germination speed can have delayedgermination
- seed orchard seed (greater) produces greaterseedlings
