Summary

THE PRESERVATION OF < ORTHODOX > SEED DOES NOT USUALLY CAUSE PROBLEMS. IT IS SUFFICIENTTO DEHYDRATE THEM AND MAINTAIN THEM AT A VERY LOW TEMPERATURE. FREEZE-DRYING COULD ALSO BE AN INTERESTING METHOD. ON THE OTHER HAND, RECALCITRANT SEEDS ARE VERY DIFFICULT TO PRESERVE, BECAUSE OF THEIR SENSITIVITY TO DESICCATION AND REDUCTION IN TEMPERATURE. THE CURRENT METHOD IS CRYOPRESERVATION, IE PRESERVATION AT A VERY LOW TEMPERATURE (GENERALLY THE TEMPERATURE OF LIQUID NITROGEN). NEVERTHELESS, SUCH A PROCESS REQUIRES A LONG DEVELOPMENT PROGRAMME WHICH DEPENDS ON THESPECIES AND ON THE ORGAN STUDIED. THIS METHOD CAN ALSO BE USED FOR SOME RECALCITRANT SEEDS.
