2014 CRYOPRESERVATION OF GERMPLASM 1; 2. Cryopreservation Cryopreservation is a non-lethal storage of biological material at ultra-low temperature.
in the preservation of genetic resources, therefore, is to reduce the fre- quency of subcultures to a bare minimum. There are two options for in vitro storage of plant materials: (1) long-term preservation at the super low temperature of liquid nitrogen (cryopreservation); and (2) short or medium-term storage under growth
Cryopreservation is a perfect method for long-term conservation of plant genetic resources, using very low temperature (liquid nitrogen, -196°C). This method has been recognized as a practical and efficient tool for the long-term storage of germplasm. Cryopreservation methods may provide the conditions for unlimited
B-5030 Gembloux,. Belgium. Keywords: Musa spp., germplasm collections, meristem culture, embryogenic cell suspensions. Abstract. Currently cryopreservation is applied mainly for safe long-term germplasm conservation of seedless and thus vegetatively propagated crops like banana (Musa spp.). Three cryopreservation
14 Mar 2012 cryopreservation are that germplasm can be kept for theoretically indefinite time with low costs and little space. Besides its use for the conservation of genetic resources, cryopreservation can also be applied for the safe storage of plant tissues with specific characteristics. Different types of plant cell, tissues
iv. Cryopreservation of Tropical Plant Germplasm. Foreword. Cryopreservation, i.e. the storage of biological material at ultra-low temperature, usually that of liquid nitrogen (–196°C), is the only method currently available to ensure the safe and cost-effective long-term conservation of genetic resources of species that have
21 Mar 1990 Cryopreservation (i.e. storage at a temperature of liquid nitrogen, -196°C) is the only technique available presently for long-term conservation of plant germplasm. For every plant species, optimal conditions have to be defined for the successive steps of the cryopreservation process : choice and.
