This study was tried to increase the survival rate of grafted
poinsettia and grafting effect on plant height by using
poinsettia cvs. Supjibi, Peter Star, Double, P8408, Freedom,
V-14 Marble, and Annette Hegg Dark Red.In survival study of
poinsettia cvs. Supjibi, Freedom and V-14 Marble, results showed
that over 50% pot grafting plants died and under 5% grafted
cutting plant died in the first week. However, lots of grafted
cutting plants died after the third week. Therefore, it was
considered that exudates would effect the survival of grafted
poinsettia. In comparison of length and leaf number of both
stock and scion, as stock length increased from 10 cm to 15 cm
with leaf number keeping from 0 to 8 or 10; and as scion length
increased from 7 to 10 cm with leaf number keeping from 0 to 1,
the survival rate increased from 1% to 90% and above. Callus are
established between stock and scion 10 days after grafting in
transverse section of paraffin embedded observation.The
restricted-branching cultivars will increase their branching
potential if restricted-branching cultivars were grafted onto
freed-branching cultivar, This study was tried to increase
branching occurrence (horizontal growth), and to inhibit the
vertical growth. Significant difference in branching occurrence
were demonstracted when restricted-branching poinsettia cvs.
Supjibi, Double and P8408 was grafted onto free-branching
cultivar cvs. V-14 Marble, and Annette Hegg Dark Red. There were
also significant differences in height after pinching when
''Double'' poinsettia was grafted on ''Annette Hegg Dark Red''.
