You want a rootstock, or the tree the graft is going into, to be vigorous and as disease resistant as possible.The quality of its fruit is not important; it is the quality of the tree that is the important part.The trees should be tall enough that the tree will have 1 to 2 feet between the trunk and the graft.Scions are the pieces of wood with three or four buds on them that will be grafted onto the rootstock. Harvest pieces that are 1/4 to 3/8 inches in diameter and that have three or four buds on them.This page does not attempt to cover the details of wood formation that make tree rings possible, but rather provides an overview of common wood characteristics and anomalies that you will need to identify when you are crossdating.Variation in these rings is due to variation in environmental conditions when they were formed.Numerous studies illustrate how ring-counting leads to incorrect conclusions drawn from inaccurate dating.Dendrochronologists demand the assignment of a single calendar year to a single ring.
These will store three to four months and still be good for grafting. Be sure to label which type of tree each scion is from.
When granite rock hardens, it freezes radioactive elements in place.
The most common radioactive element in granite is Uranium-238.
Other atoms are also named based on the number of protons they carry.
Notice in the diagram that eight different isotopes of Carbon are illustrated.
