The seed in the serotinous cones of jack pine have long been assumed to be an important factor in the regeneration of stands of this species. Very little definite information on the quality of this seed has been available. The following study based on 1,400 tests of seed collected from 92 trees shows that there is a statistically significant drop in the quality of seed from three year old cones. The drop is not great and from a practical standpoint even the oldest seed is valuable. The moisture content of cones of various ages indicated that constant moisture content is a more important factor in maintaining viability than temperature.
