The Effect of Season of Sowing, Storage Treatment, And Hulling on Germination and Growth of Black Walnut Seed

The demand for black walnut seedlings in recent years has often exceeded the supply, and lack of seed is the reason generally given for the limited seedling production. This problem, and the fact that nurserymen are becoming more selective in choosing walnut seed sources, make it increasingly important to find out how to augment seedling yield from a limited amount of seed. The research reported here shows that fall sown seed produces more seedlings at most Central States nurseries than spring sown seed. And because the fall sown seed germinated sooner, the seedlings produced were usually larger than those produced in spring sown beds. Hulling the nuts did not affect seedling yield, but hulling reduced volume by about two-thirds, thus making it easier to stratify and store the seed.
