Malpighi’s girdling, or tree , is
the removal from stem of a complete
girdle containing the phloem
( is more external) but
the xylem (that is internal).

When a girdle that is removed
below branches the plant dies
organic food (sugar) is
to pass to the below
the girdle and roots die from the
of nutrients. Since roots the
plant does not water and mineral
salts dies too.
