All plant cuttings need rooting
regulators, called auxins, to make roots. The plant itself
produces these natural auxins, in limited quantities within the
leaves and meristems. When we take cuttings from the mother
plant, the auxins are stored at the basal ends.
Let us look inside a cutting.
Natural auxins, produced
by the plant, are translocated from the growing leaves and
meristems to the basal end of the cutting. The auxins move from
cell to cell by polar transport. Polar transport takes place in
the xylem, phellogen, and other transport vessels in the shoots
and stems.
The plant makes use of
natural transport proteins. These proteins allow the auxins to
be taken into the top of the plant cell, move through the cell,
and be released at the bottom of the cell. Cell by cell, the
auxins are taken in by the underlying cells. In this way, the
plant transports the auxins downward. Polar transport of the
auxins occurs at a speed of approximately one centimeter, or
about half an inch per hour.
The auxins accumulate in
the basal ends of the cuttings. When the amount of auxins at the
basal ends of the cuttings exceeds a boundary level then the
cells re-program themselves. Afterwards, these cells become root
cells.
Usually, natural auxin
production in the cuttings is not sufficient. Only occasional
roots may form. Some cuttings may have delayed rooting or may
not form any roots. Developing roots that are evenly spread out
at the basal ends of the cuttings is important. Strong rooting
systems assure quality plant development and health.
When you supplement the natural auxins with a bio-simulator of
the natural auxins, as found in the Rhizopon products,
consistent and uniform roots are achieved. Rapid and steady
rooting occurs around the base of the cuttings. Therefore, it is
easier to adjust the growing environment and to produce a
healthy crop.
