Storing sand pine seeds and cones

Viability of seeds from new and 1-yearold Ocala sand pine cones remained essentially unchanged after 10 years of storage at all combinations of 6-, 9-, 12-, and 15-percent moisture contents and 0° and 34°F. temperatures.

Viability of seeds in stored, serotinous Ocala cones remained high for 3 years, but decreased steadily during the following 6 years
