- Intervention effect Increasing nursery drought increased lodgepole pine survival after planting.
- Intervention effect High nitrogen increased lodgepole pine survival.
- Intervention effect High nitrogen increased white spruce survival.
- Intervention effect Combined nursery drought and high nitrogen increased lodgepole pine survival by 33% under xeric conditions.
- Intervention effect Increased nursery drought decreased seedling size relatively little.
- Intervention effect Increased nitrogen increased seedling size one season after planting.
- Association Shoot/root ratio related positively to survival in lodgepole pine.
- Association Shoot/root ratio related positively to survival in white spruce.
- Observation Only Douglas-fir showed a drought by nitrogen interaction.
- Intervention effect Douglas-fir had a small survival response to potassium.
- Intervention effect Douglas-fir had a small dry-weight response to potassium.
- Intervention effect High nitrogen approximately doubled root growth capacity in all three species.
- Intervention effect Drought stress increased white spruce root growth capacity.
- Association Survival and root growth capacity were poorly correlated.
- Association Dry-weight growth in sand beds correlated well with root growth capacity.
- Association Shoot dry weight and shoot nitrogen percentage correlated with root growth capacity.
