Liquid nitrogen has several advantages over storage of vegetatively propagated material under normal low-temperature in vitro culture and could also help in preserving genetic biodiversity. Development of efficient cryopreservation protocols based on the induction of tolerance to freezing and/or desiccation is also discussed. Cold and/or preculture acclimatization leads to ultra- structural, physiological and molecular changes in cells and they are important for improving viability after cryopreservation. The application of vitrification-based procedures and ultra-fast freezing/thawing rates could be effective and reliable for wide variety of plant species/tissues and relatively genotype independent. Majority of papers demonstrate that the liquid nitrogen allows high viability rates and re-growth without a loss of biosynthetic capacity. Up to now, there has been no clear evidence of morphological, cytological or genetic alterations due to cryopreservation.}, title={Cryopreservation as a method to facilitate presenation of life capacity of plant cells and tissues}, type={Text}, URL={http://rcin.org.pl/Content/73837/PDF/POZN271_96631_biotechnologia-2008-nr2-mikula.pdf}, keywords={biotechnology}, }
