(some specimens in France surviving for 200 years)

• Leaves are opposite or sub opposite, glossy, narrow oblong, entire,

3–7 cm long and 2 cm broad.

• The flowers are bright red and 3 cm in diameter, with three - seven

petals.

• The name pomegranate derives from medieval Latin pōmum "apple"

and grānātum "seeded".

• granada in Spanish.

• delum in Sri Lanka.

• grenade in French.

• mātuḷa in Tamil.

• romã in Portuguese. ETC..

PROPAGATION METHODS

• SEEDS

• An easy method of propagation is to do it by seeds (because seeds are

germinate very quickly) even if sprinkled on the top of the soil.

• HARDWOOD CUTTINGS

• Hardwood cuttings are the most widely used method.

• We must take the cuttings (November through January) off of one-year-old

wood.

• After cutting we must protect and let them develop some roots in a greenhouse

before planting.

PROPAGATION METHODS• GRAFTING

• Grafting of pomegranate trees is rarely done in some countries.

• And we have to protect the grafting point until it grows.

• TISSUE CULTURE

• Use tissues seeds or cuttings.

• This is a good method but it is more expensive method.

DISEASES

• Bacterial Blight of Pomegranate

• spots are black and round and surrounded by bacterial ooze.

• later spots enlarge to become raised, dark brown lesions with indefinite margins that

cause the fruit to crack.

• Anthracnose

• causes spotting and rot of pomegranate fruits

• caused by viruses

• Pests in pomegranate

• they sucking fruits and harm to their development.

PESTS IN POMEGRANATE

Ants Grape Mealy bug

Cherry Leaf hopper Leaf footed Plant Bug

Citrus Flat Mite Soft Scales

Cotton Aphid Whiteflies

Filbert worm Katydids

• fruit rot

• there are 3 types of rotting

• 1. Alternaria fruit rot (Alternaria alternate)

• 2. Aspergillus fruit rot (Aspergillus niger)

• 3. gray mold (Botrytis cinerea)

PREVENTING METHODS OF DISEASES

• can mainly categorize in to 3

• cultural control

• chemical control

• biological control

cultural control

1. watering

most fungi and bacteria need water for their germination. so

#splashing water

#careful watering

#proper timing of watering

will help to prevent many fungi and bacterial diseases.

2. sanitation

we must remove or burn all diseased plants and we must keep our crops cleanly.

3. pruning

should prune out infected portions just like wilts, cankers and galls.

Chemical control

if the parasite's damage become more severe we can apply chemicals to

control them. there are many fungicides , bactericides in the super market.

and remember to be careful when you work out with chemicals.

Biological control

The Cryptoleamous montrozieri (BiyoAvci) and Leptomastix dactylopii (BiyoAri) should

be used together in the pomegranate orchards which have mealy bug problem.

Release of egg parasitoid Trichogramma species was found effective to control the

pest.

HARVESTING TECHNIQUES

• Can harvest manually or mechanically. but mostly pomegranates

harvest in manually.

• Must harvest our crops in correct time.

• Normally harvesting after 3,4 years.

• Harvest it only after it has reached full maturity.

• In harvesting in manually they use small devices also. such as knives,

scissors , ladders , plucking instruments etc.

FINAL PRODUCTS FROM POMEGRANATE

• pomegranates are used in

• Juice blends and smoothies.

• Alcoholic beverages( such as cocktails and wine ).

• Make delicious food items using pomegranate in five star hotels.

• Meal products ( jam , cordial , saus , and other meals ).

• As herbal products (green tea , vitamins , medicines).

• As beauty-boosting products (powder , cream , soap , body wash ,

lipsticks ).
