Summary

DESICCATION-SENSITIVE SEEDS, ARECA PALM (CHRYSALIDOCARPUS LUTESCENS) AND SILVER MAPLE (ACER SACCHARINUM), DID NOT SURVIVE DEHYDRATION BELOW THE THRESHOLD MOISTURE LEVEL, AT WHICH SEED TISSUE WATER WAS IN AN UNFREEZABLE STATE AND DID NOT SURVIVE EXPOSURE TO LIQUID NITROGEN. SEEDS FROM STRAWBERRY GUAVA (PSIDIUM GUAYAVA), PASSION FRUIT (PASSIFLORA EDULIS), CEARA RUBBER (MANIHOT GLAZIOVII), DWARF SCHEFFLERA (SCHEFFLERA ARBORICOLA), PAPAYA (CARICA PAPAYA), APPLE OF SODOM (SOLANUM SODOMEUM L.), PRICKLY POPPY (ARGENOME GLAUCA POPE) AND SEAMBERRY (SABAL PAMIFLORA BECC.) SURVIVED DEHYDRATION TO AS LOW AS 2 TO 12% MOISTURE CONTENT AND EXPOSURE TO LIQUID NITROGEN. COFFEE SEEDS TOLERATED DEHYDRATION TO AS LOW AS 8% BUT DID NOT SURVIVE EXPOSURE TO LIQUID NITROGEN.
