Improvement of Stock Quality in the Forest Nursery
The application of forest tree improvement will be largely through tree planting. Consequently much of the seed developed in seed production areas and seed orchards, or from special selections, hybrids, or other controlled pollinations will be used to grow nursery stock. It will be especially important, therefore, to use nursery practices that will produce the largest feasible proportion of high-quality planting stock. It is possible, too, that seedlings of inherently high vigor can be selected in the nursery and thus provide a shortcut in forest tree improvement. Such selection must be based on comparison with other seedlings growing under similar uniform conditions. This implies good nursery management. For these reasons there is given here a brief resume of nursery practices that are known to foster the production of high-quality planting stock. Included also is some evidence of the effectiveness of these practices.
