69. propagation
seeds
• collected from small flowered
varieties
• Collected when blooms are dried
• sown in earthen pots or nursery
beds
• covered with a thin layer of leaf-
mould and soil and watered
• They germinate within 7-10 days
• Seedlings are ready for
transplanting within 40 days
• Seedlings propagation method is
not used normally for routine
cultivation
•
cuttings
• Terminal cuttings of stock
plants are taken in June
• They are transplanted after
rooting in 15cm (6”) pots
during June-end
• These plants are ready for
pinching during July-end or
beginning of September
• When a plant attains 8-10
leaf stage ,first pinching is
done by removing the
terminal portion (with 2-3
leaves)
• Lateral shoots develop from
below the cut

70. Mum cuttings planted in a 6-inch pot. The
cuttings are slanted toward the outside of the
pot at an angle of about 45 degrees.

111. Chrysanthemum was
one among the plants
selected by NASA as
the best filterer of
space station’s air—not
only producing oxygen
from CO2, but also
absorbing benzene,
formaldehyde, and
trichloroethylene

114. Harvesting stage
When outer florets fully expand
Flowers open but before shedding of
pollen
Centre of the oldest flower fully open
Open but before the central disc florets
starts to elongate
