“Agriculture makes life bearable but Horticulture makes life worthwhile”

1. “Agriculture makes life bearablebut Horticulture makes life worthwhile” “Pertanian menyangga kehidupan, namun Hortikultura membuat hidup ini lebih berharga dan berdaya guna”

2. Say it with Flower

3. List Priority the Research Program

4. Sedap Malam (Polianthes tuberosa) • Centre Product : • Brastagi • Sukabumi • Bandungan • Bangil • Icon of Malang (?) or East Java • Export to Japan and Europe

5. When the biggest of demand ??? • Christmas and New Year • Idul Fitri • Imlek • 17 Agst • Market : Jakarta, Bandung, Medan, Bogor, Solo, Semarang, Yogja, Malang, Denpasar, Ujung Pandang

6. Classification • Kingdom : Plantae • Division : Spermatophyta • Sub-Div: Angiospermae • Class : Monocotyledonae • Ordo : Amaryllidales • Family : Amaryllidaceae/ Liliaceae • Genus : Polyanthes • Species : Polyanthes tuberosa L

7. 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

8. 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

9. 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

10. Influence of temperature treatment of bulbs on vegetatif growth and flowering of tuberose 1. Days required for sprouting of bulb 4. Days required for flowering 2. Plant height(cm) 5. Number of flower spike /clump 3. Number of leaves / clump 6. Length of flower spike (cm) 7. Flower yield (ton/ha)

11. Effect of chemicals on growth and flowering of tuberose 1. Days required for sprouting of bulb 4. Days required for flowering 2. Plant height(cm) 5. Number of flower spike /clump 3. Number of leaves / clump 6. Length of flower spike (cm) 7. Flower yield (ton/ha)

12. 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

13. 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

14. Effect of bulb size on growth of tuberose (1)

15. Effect of bulb size on growth of tuberose (2)

16. Deepth of Planting

17. 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
