Peach Tree

Even if pruning cuts are made correctly on some trees such as peach trees, large columns of symplastless wood may form below cut.  Or better said "a column of symplastless wood" may form.

Above:  Round doughnut shaped woundwood has formed suggesting this was a properly made cut.

Above:  This dissection reveals that a large column of color altered wood (brown) has formed below this cut.  The thin white columns outside the color altered wood still maintains a symplast.  The capacity of this stem to store energy has greatly decreased even though pruning cut was correct.  Why, trees only store starch in living cells of the symplast.  Maybe this is why peach tree suffer from short-life disease.  Imagine the amount of color altered wood that would have formed if this was an incorrect cut?
