Production technology of chrysanthemum
Protected cultivation HORTICULTURE practices
Scope and importance of chrysanthemum
Light and temperature management in chrysanthemum
6. Species to be remembered
C.Morifolium = Florists chrysanthemum
C.rubellum= Breeding for hardy cultivars
C.cieraifolium= pyrethrum extraction (potential insecticide)
C.carinatum= Tricolour Chrysanthemum
7. TH FLORISTS’ POTTED CHRYSANTHEMUM IS A COMPLEX HYBRID COMPOSED OF
CROSSES AMONG SEVERAL ANNUAL AND PERENNIAL SPECIES NATIVETO CHINA.
THOUGH GROWN BYTHE CHINESE FOR OVER 2000YEARS, CULTIVARS WERE NOT
AVAILABLE IN EUROPE UNTILTHE 18005.
→INTHE UNITED STATES AROUND 1889, ELMER D. SMITH HYBRIDIZED AND
NAMED OVER 500 CULTIVARS. → HOWEVER, REAL DEVELOPMENT OFTHE
CHRYSANTHEMUM AS A POT CROP HAS OCCURRED SINCETHE 1940’S.
THE CHRYSANTHEMUM USED IN POT CULTURETODAY IS A HARDY OR SEMI-HARDY
HERBACEOUS PERENNIAL WITH FLOWERS IN AWIDE RANGE OF COLORS.
LETS DIG INTOTHE HISTORY
8. TYPES OF CHRYSANTHEMUM
IRREGULAR INCURVE :-
1. THESE ARETHE GIANT BLOOMS OFTHE
CHRYSANTHEMUM GENUS.
2. THE FLORETS (PETALS) LOOSELY INCURVE AND
MAKE FULLY CLOSED CENTERS.
3. THE LOWER FLORETS PRESENT AN IRREGULAR
APPEARANCE AND MAY GIVE A SKIRTED EFFECT.

21. Soil requirements
SOIL SHOULD BE LEVELLED PROPERLY.
COCO PEAT SHOULD BE ADDEDTO IMPROVE
STRUCTURE &WATER HOLDING CAPACITY.
IF GROWING 1ST TIME, SOIL SHOULD BE
DISINFECTED USING FORMALDEHYDE
pH range : 5.5 to 7
22. Chrysanthemum is propagated vegetatively
through suckers, cuttings or by micro-
propagation. After flowering, the stem is cut
back just above the ground.This induces the
formation of side suckers which are separated
from the mother plant and are planted in sand
bed.
Spacing followed is 30*30 cm in the rooted
suckers
PROPAGATION OF CHRYSANTHEMUM
23. Classification based on response to
temperature
Thermo zero cultivars: flower at any temperature between 10⁰ to 27⁰ but most
constantly at 16⁰c night temperature.
Thermo positive cultivars : Continuous low temperature between 10-13⁰C inhibit
or delay flower bud initiation and at 27⁰C there will be rapid initiation but
delayed flowering.
Thermo negative cultivars: which bud initiation occurs at low temperature delay
bud development occurs
24. PHOTO PERIOD REGULATION
Long day & Short day period
Growing chrysanthemum at day length longer than 16 hours- vegetative growth.
After 18-35 days – when plant height is 30-40 cm- short day treatment should start
Day length longer than 16 hours results in vegetative growth
The height of the plants should be between 30 and 40 cm to start short day
treatment.
The numbers of days taken to have enough vegetative growth vary between 16
and 35 days depending on desired stem length, variety, climate and cultural
practices.
25. ARTIFICIAL LIGHT MANAGEMENT
Lighting :60 watt lamp, 4 ft apart, 2 ft above (4 hours extra).
It is mostly followed in the poly hosuses under protected
cultivation but if you have more money which you don’t
want to spend on poly house but want to spend on lights
then we can do it in open filed cultivation also as anything is
possible if we have more capital
Darkening:Cover black polythene (150 gauge) for 4-5 pm to 7
am in the morning
This induces short days and ensures flower initiations
26. Light and photo period
management in
chrysanthemum for
controlling vegetative and
reproductive growth
27. CULTURAL PRACTICES
1.Pinching based on intensity it’s of 3 types
Soft pinching
Hard pinching
Roll out pinching
2. De suckering to remove extra suckers
3.Staking
4.Disbudding
5.Deshooting

After Harvesting the flowers can be transported by packing in special
perforated cardboard boxes
