Summary

QUANTITATIVE GERMINATION TESTING INVOLVING LONG-TERM AXENIC CULTURING IS USED TO DEMONSTRATE THAT NO DETRIMENTAL EFFECT ON EMBRYO GROWTH AND DEVELOPMENT IN TERRESTRIAL AND EPIPHYTIC ORCHID SEED OCCURS AS A RESULT OF EXPOSURE TO LIQUID NITROGEN TEMPERATURES. IN ONE TERRESTRIAL SPECIES, ORCHIS MORIO, LIQUID NITROGEN TREATMENT PROMOTES EMBRYO EMERGENCE WITH A MAXIMUM 20% INCREASE AFTER FOUR FREEZE/THAW CYCLES.
