Bareroot stock survived 

 and grew best on the 

 site with heavy vegeta- 

 tive competition. 



Bullet plug performed 

 best on drier sites. 



Containerized stock 

 showed superior 

 survival. 



Differences were not 

 significant 



Differences were not 

 significant. 

 Variable results. 



Containerized stock was 

 superior in survival and 

 height growth. 



Containerized stock per- 

 formance was superior 

 to bareroot and differ- 

 ences were greater on 

 dry sites. 



Bareroot stock per- 

 formed better than 

 containerized stock. 

 Results were variable 

 but overall containers 

 performed as well as 

 bareroot. 



In plantings made after 

 March, containerized 

 seedlings had greater 

 survival. For trees 

 planted in February and 

 March (shorter storage 

 period) bareroot was 

 best. 



Higher survival rate of 

 containerized stock was 

 not significantly better 

 than bareroot. Bareroot 

 height growth was best 

 but again, not signifi- 

 cantly better. 



Bareroot survival and 

 growth was significantly 

 higher than containers. 

 Bareroot stock showed 

 higher survival and 

 height growth. Survival 

 differences were 

 significant. 



There were no differ- 

 ences in survival but 

 bareroot height growth 

 was significantly greater.
