Classification
•
•
•
•
•
•
Kingdom : Plantae
Division : Spermatophyta
Sub-Div: Angiospermae
Class : Monocotyledonae
Ordo : Amaryllidales
Family : Amaryllidaceae/
Liliaceae
• Genus : Polyanthes
• Species : Polyanthes
tuberosa L
• Discus : truly stem
• Bulb : Batang semu
• The root system :
- Spread through away
- Radius : 40 - 60 cm
- Akar serabut
- Bulb :
1 clump consist of 1 or many mother bulb &
groups of new bulb
Mother Bulb  Big size bulbus (lap.umbi)
not clearly the colour, white
For vegetative propagation
• Leaf  Long and thick, the color of the
surface is light green surface, and inside is
young green. Pada pangkal daun bintik
kemerahan
• Siclus  Annual, more than 1 years
• Reproductive phase  stalk rise from bottom
of the plant – with internode  every node
with flower leaf  panjang pipih lebih kecil
dari normal leaf
• Tiap tangkai  5 – 12 kuntum bunga, mekar
tidak bersamaan, mahkota warna putih, ada
yang kemerahan
• Bila dipotong 2-3 kuntum terbawah mekar 
tahan 5 – 10 days  for cut flowers
• Sedap malam  succulent/ herbaceous plant.
Life cyclic :
1-2 week after planting  keluar bud & roots
3 -5 wap  leaf beginning growth / initiation of
leaf
16 – 20 wap  optimal leaf growth
24 – 26 wap  keluar tangkai flower
• Bila dibiarkan bunga gugur  terbentuk umbi
anakan, 36 wap  new plant
7 – 9 month  bakal bibit

• Prepare for stock plants
20 x 20 cm  1 bulb/plant hole
Mother plant > 2 years  health and productive
Bulb has appear shoot  storage time
min. 1-1,5 month
Fresh bulb : Vegetative growth + Little flower
Keep it for few week  better
Propagation
• Vegetatif : Bulb, Division,
Micropropagation
Bulb  ± Ø 1.5 cm
9 – 12 bag / bulb
• Generatif : Seed  difficult
• Micropropagation : 3000 Lux, 250C ± 20
9 -12 bag/bulb
for shoot-root  MS + 3 % Sucrose
2.0 mg BAP + 0.5 mg/l kinetin
+ 0.2 mg/l NAA
+
MS + 1 % sukrose + 2.0 mg/liter IBA +
0.2 mg/l kinetin

Harvest and Postharvest
• Qualified harvest  age of plant 7 – 8 month after
planting
• Stalk of flowers have 2-3 blossom
• Cut flower & Sowing flower
Population 200.000 / Ha  160 stalk 1 st harvest
2nd harvest – ratoon
• 10 – 100 stalk / ikat
• Long vaselife  recut stalk under water and place them
in the water with preservative, or
• sugar 6 %  6 gram / 100 cc water  vase life 13 – 14
days
