    Untrained collectors of hardwood seeds often start picking the seeds too early in the year. The immature seeds germinate poorly, if at all, and nursery production suffers. In the study reported here, sweetgum (Liquidambar styraciflua L.) seeds collected in central Mississippi in mid-August were ripe. Seeds collected as early as July 19 were artificially ripened by storing the seed heads until late September in a cool, moist environment. ltipening treatments improved germination in both 1967 and 1968. The detailed tests of 1968 are described here.
