Planting Research 



In planting research, the over-all objective has been the establishment 

 of experimental plantations to test theories advanced which might have practical 

 applications in the field of reforestation. 



(a) Survival counts were made on the spacing plantation established in 

 1950. This test plantation is comprised of four coniferous species planted at 

 three spacings and replicated three times* 



(b) Survival counts were made on the root pruning and root induction 

 experiment established in 1953 • This test plantation is comprised of three 

 coniferous species planted *ith two degrees of root pruning, one root induction 

 treatment, with the necessary controls. In 195^ an identicetL plantation was 

 established for fxirther studies in this project. 



(c) Survivsil studies were made on plantations established in 1953 which 

 consisted of trees which had been held in cold-storage over a season. This 

 project was initiated to test the effects of summer planting of trees v^ich had 

 been spring lifted and cold-stored until the planting time. Three coniferous 

 species were test-planted in this way. A further plantation was established 



in 195^ in the same manner, but utilizing four coniferous species. 



(d) Small block plantations of species not native to north-western Ontario 

 were established in 195^. To test adaptability, plantations of Norway spruce, 

 lodgepole pine, Dunkeld larch, and B.C. fir were established* 



Seeding Research 



As in planting, the objective of artificial seeding research has been 

 to test seeding theories which might have practical uses in forestry. Inoorporatod 

 with these practical trials are small-scale basic research studies. In 195^9 

 this program consisted of the following s 



(a,) Making survival coiints and analysing the results in the spring and fall 

 of the shade and protection tests established in 1953* These tests are aimed at 

 determining the effects of fall exposure, partial shading, full shading, and 

 oaging on seed spots« 



(b) Making an examination of the results of the comprehensive seed-probo 

 test established in 1952, in eo-operation with the Great Lakes Paper Company*
