CRYOPRESERVE 1815 ELM TREE
Perth Amboy , New Jersey, has, in its city hall yard, an Elm tree planted in 1815 which has
withstood bouts of Dutch elm disease and poundings of brutal storms for over 200 years. The tree is
considered a symbol of the sea coast town 's strength and ties to the nations history.
Agriculture researchers and the officials of the city want to ensure the genetic heritage of this
tree. Originally, the plan was to save the elm's seeds by the cryopreserve method, but it was found
because there was no other elm tree nearby to pollinate the flowers, therefore there were no embryos
within the seeds. Now, twigs, cut from the aging trees branches, will be stored in a 'flash frozen ' state
for decades or even centuries. That's what the crypreserve method is.
New Jersey's DEP , USDA, the national laboratory of Genetic Resources Preservation in
Colorado are the principals involved in this effort.
