PROPAGATE CHIMERAS BY LEAF CUTTINGS - WHY?
the same reasons - never use root cuttings)

LEAF PATTERNS OF CHIMERAS
below demonstrate two types of variegated Elaeagnus. The cultivar
on the left is a L-II chimera (i.e. GWG), and the cultivar on the right
is a L-III chimera (i.e. GGW). These are chimeras where the yellow
or albino regions cannot make chlorophyll. A cross-section of the leaf
shows the regions of albino cells in the mesophyll. The different
shades of green and yellow are determined by the depth of the cell layers.
SHOOT FORMATION ON LEAF CUTTINGS OF CHIMERAS
take leaf cuttings from variegated plants, such as these variegated Peperomia
(GWG), the plantlets that form are never true-to-type to the parent
variegation. The reason is simple. The adventitious shoots
that form will have the properties of the region of the leaf from which
they regenerate. The same would happen with a root cutting.
For this reason, chimeras are never propagated true-to-type by cutting
types or methods that require adventitious shoot formation.
