The efficiency of garlic cryopreservation is, amongst other factors, depending on the origin of the donor explants. So far, in vitro grown material has always been the least responding one with respect of the regrowth rates. On the other side, the possibility to produce virus-free material via meristem culture and to keep these clones then under isolated conditions in a clean culture induced studies to increase the efficiency of cryopreservation using this kind of material. Experiments have been performed to use various materials and cultivation temperatures for a vitrification protocol. Best results (up to 70 % regrowth) were obtained with cultures grown for only 10 months under in vitro conditions including a cold preculture of two months either at alternating or at permanently low temperatures. The conclusion was drawn that the quality of the explants and temperature conditions play a major role for the efficiency of cryopreservation using in vitro plantlets.

More about this publication?
CryoLetters is a bimonthly international journal for low temperature sciences, including cryobiology, cryopreservation or vitrification of cells and tissues, chemical and physical aspects of freezing and drying, and studies involving ecology of cold environments, and cold adaptation
The journal publishes original research reports, authoritative reviews, technical developments and commissioned book reviews of studies of the effects produced by low temperatures on a wide variety of scientific and technical processes, or those involving low temperature techniques in the investigation of physical, chemical, biological and ecological problems.
