In vitro (test tube) culture of plants at NCGR-Corvallis serves several important functions. This method provides an efficient means of preserving large numbers of plant clones in a small space. At temperatures just above freezing, these plants require little maintenance for a year or more. These miniature plants do not need water, fertilizer, or sprays. In vitro culture of plant meristems is also an important step in the elimination of viruses from infected plants.
Plants in this sterile environment, free of insects and most diseases, can be readily shipped to scientists throughout the world. Approximately 1500 growing plants are presently stored at 4 degrees Celcius. Storage life ranges from 1.5 to 4 years. Research is underway to optimize the growing media and environmental conditions for culturing the repository crops.
