Our research followed the growth of the triticale plantlets, in first 6 days of germination, after cariopses (with 6.89% degree of humidity) storage by immersion in liquid nitrogen (-196ÂșC), for variable periods of time: 5 minutes, 1 hour, 1 day, 1 week or 1 month, in proportion with the same parameters of the control lots, which were not treated with liquid nitrogen. After triticale grains immersion in liquid nitrogen and than defrosted and taken for germination we registered a statistically non-significant inhibition in the growth in length of the vegetative organs (primary and adventitious roots, coleoptils and first leaves ) of the triticale plantlets.
