2. Introduction
 Family Araceae
 Flower arranged as an inflorescence
 Bisexual flowers
 Popular cut flower with long vase life

3. Lobes
Flower Stalk

4. Propagation of Anthurium
1. Vegetative / asexual propagation
a. Stem cuttings
b. Axillary buds
c. Suckers
d. Tissue culture
2. Sexual propagation – by seeds

5. Vegetative propagation
Stem cuttings
 More mature plants produce leggy stems that is
unable to stand erect or that has outgrown the
pot
 These plants produce smaller leaves, smaller
flowers and shorter flower peduncle and leaf
petioles

6.  The top portion (apical portion) of the plant is cut
away with few roots and replanted
 The remaining bottom portion (basal portion) is
used for vegetative propagation

7. Method
 The basal portion can be cut in to 1.5”- 2” long
pieces with 2 – 3 growing points
 Dip them in a diluted KMnO4 solution or a
fungicidal solution
 Plant horizontally in 1:1 mixture of sand and leaf
mould or sand and coir dust

8.  Provide shade and water
 After few weeks the dormant buds spring up and
grow into plantlets
 They can be planted in their proper place (pot or
bed) or transferred into polythene bags to grow
bigger

9. Axillary buds
 Top portion is removed in older plants
 It activates axillary buds and produce shoots
 Those shoots can be separated planted as a new
plants
Suckers
 When mature, mother plant produces suckers
 After producing 3 – 4 leaves, suckers can be
separated from mother plant

10. Tissue culture
 As the ex – plant; leaf lamina, leaf petiole,
spathe, spadix or peduncle can be used

11. Sexual propagation
 Female part of the flowers mature 7 – 10 days after
flower opening
 Male parts mature 7 – 14 days after female parts
maturation
 When female parts mature it becomes sticky and
stigma can be observed as tiny dots
 It takes about 3 – 4 consecutive days to mature
female parts from the base of the spadix
 When male parts mature, it produces powdery film
on the spadix

12. Pollination
 Pollination is done when the spadix is sticky to
touch
 Powdery pollen from another flower is collected
from a paint brush and apply on a sticky spadix
 It should be continued for 3 – 4 days, before 10
a.m.
 After pollination, the flower is covered from
transparent polythene

13.  Within 1 month the spadix becomes thick and
green and it is a sign that pollination has been
sucessful
 The berries take 5 – 6 months to mature and
plucking can be done when it turns to yellow or
orange in colour

14. Method
 Gelatinous cover of the ripen berries are gently
removed and washed 2 – 3 times with water
 Dip them in a diluted KMnO4 solution
 Prepare a shallow pot or seed pan for seed sowing
 Put layer of brick pieces at the bottom
 Then add a layer of decaying leaf mould and then
Anthurium potting mixture
 Then put layer of ½” long brick pieces

15.  Then spread seeds on it (1” space)
 Keep the seed pot / pan on a shallow water
basin and watering
 Cover it with polythene / glass
 When the seedlings are around 6 months old
they can be uprooted and replanted in polythene
bags to grow bigger prior to transferring to the
permanent location

16. Potting of Anthurium
Potting mixtures
Leaf mould/ compost/ coir husk pieces - 4 parts
Decayed cattle manure - 2 parts
River sand - 1 part
Or
1” decomposed coconut husk pieces - 1 part
Decayed cattle manure - 1 part
Rough sand - 1 part

17. Method of potting
 Prepare a drainage hole in the bottom of the pot
 Place broken tile piece over the drainage hole
with the concave side facing downward
 Put a layer of brick pieces to 2” height
 Add a layer of leaf mould over the brick layer
 Fill the pot with the potting mixture until ¾ from its’
height

18.  Select a healthy plant with 3 – 4 leaves and place
the plant in the center of the pot with roots spread
 Add more compost around it and press down
 Do not burry the growing point
 Leave 1 inch space from the medium to the top of
the pot
 Provide a support for weak / long stemmed plants
 Water the plant and keep in a shady place for few
days
