{image-oldest tree1_17042008.jpg}Washington, Apr 17: World's oldest known tree is 9,550 years old and is a spruce tree in Sweden. The tree lies in Dalarna province of Sweden. The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time.

''Our results have shown the complete opposite, that the spruce is one of the oldest known trees in the mountain range,'' Professor of Physical Geography Leif Kullman said, Science Daily reported. A fascinating discovery was made under the crown of a spruce in Fulu Mountain in Dalarna. Scientists found four ''generations'' of spruce remains in the form of cones and wood produced from the highest grounds. The discovery showed trees of 375, 5,660, 9,000 and 9,550 years old and everything displayed clear signs that they have the same genetic makeup as the trees above them.

Since spruce trees can multiply with root penetrating braches, they can produce exact copies, or clones.

The tree now growing above the finding place and the wood pieces dating 9,550 years have the same genetic material. The actual has been tested by carbon-14 dating at a laboratory in Miami, Florida, USA.

Previously, pine trees in North America have been cited as the oldest at 4,000 to 5,000 years old.
