study, seedling growth was slower than what we had 

 hoped for with both treatments. 



Although the shape of root systems differed, the amount 

 of roots in the upper 12 inches of soil was similar for both 

 kinds of stock. An infestation of shoot borers reduced the 

 mean heights slightly but was not related to treatment 

 and did not affect our conclusions. 



After five growing seasons, survival averaged 90 per- 

 cent for all containerized grown seedlings and 79 percent 

 for bareroot stock. On the good sites not much is gained 

 by planting containerized trees, but on the poor sites con- 

 tainerized trees will definitely outperform bareroot stock.
