There was little differ-

There was no significant 

 difference in survival 

 and height growth be- 

 tween containerized and 

 bareroot stock. 

 There was little differ- 

 ence in survival but 

 bareroot seedlings were 

 significantly taller. 

 There was little differ- 

 ence in survival but 

 bareroot seedlings were 

 significantly taller. 

 Results were mixed. 

 Neither bareroot or con- 

 tainerized seedlings 

 were consistently better 

 than the other in growth. 

 Overall, bareroot 

 seemed to have greater 

 survival. 



Little difference in 

 survival. 



Containerized stock 

 seemed to perform bet- 

 ter than bareroot on 

 north slopes. Containers 

 were clearly superior on 

 south slopes. 

 Bareroot survived and 

 grew better on a very 

 dry site.

Bareroot stock did not 

 survive August planting. 

 Bareroot stock showed 

 very poor survival in 

 November planting. 



Containerized stock was 

 superior to bareroot in 

 June plantings. 



Containerized stock was 

 superior to bareroot.
