to Plant Propagation
To produce new plants which
are exactly like the parent plants in your home, garden, nursery or
greenhouse, use a technique that involves rooting existing pieces of the
plant. To produce a plant which is genetically identical to the
mother plant "clonal asexual" (also called
"vegetative") propagation is needed. Propagation by the
rooting of stem cuttings, root cuttings and division, layering, and
grafting, and similar techniques all produce new plants that are identical
to the original.
The selection of the method is
dependant upon the plant variety. Propagation from seed works mainly
for annual plants, but often produces variable results. You never
know what you will get from seeds! See Cuttings
and Grafts, Division and Layering
and Grafting and Budding for
information on the propagation methods.
Plants propagated from cuttings have
the same characteristics as the parent plant. The rapid generation
of new roots is necessary for the plant to transport water and essential
nutrients from the media. Rooting hormone treatment helps the plant
to rapidly develop new roots when propagating from cuttings, and humidity
must be kept high while the plants root. Different types of cuttings
require different hormone concentrations, so make sure you use the right
type - some are for woody stems, and others are for young green shoots.
The most attractive plant is a
symmetric plant. After early and symmetric root formation the plant
stands solid in the soil, it absorbs water and nutrients, develops uniform
shoot, stem and leaf growth and superior total growth. This is why
you get a bigger, better plant from a cutting than you do from starting
with seeds. See
Care of Cuttings for more information.
Propagation of plants by various methods is not a
mystery. Some plants propagate better by different
"vegetative" means, and some just don't propagate well at
all. See Plants to Propagate
for lists of houseplants, ornamental garden plants, shrubs and trees that
work well, and those to avoid.
