Taxonomy

Family:Lythraceae

Genus:Punica

Species:granatum

plant structure
Plant Structure
  • The tree:
    • Rounded shrub or small tree 12 to 16 ft. in height.
    • Usually deciduous
    • Stiff, angular branches, often spiny.
    • Long-lived tree.
    • Vigor declines after about 15 years.
plant structure6
Plant Structure
  • Leaves and flowers:
    • Glossy, leathery leaves that are narrow and lance-shaped.
    • Flowers have a bright red color and 5 to 8 crumpled petals
    • Red, fleshy, tubular calyx which persists on the fruit.
    • Self-pollinated
    • Cross-pollination (insects & wind)
    • Blooms from early May to November
    • Flowering from mid May to early June
plant structure7
Plant Structure
  • Fruit
    • Round shaped (2-1/2 to 5 in.)
    • Tough, leathery yellow/red skin or rind.
    • Interior is separated by membranous walls and white, spongy, bitter tissue into compartments packed with sacs filled with sweetly acid, juicy, red, pink or whitish pulp or aril.
    • Each sac have one angular, soft or hard seed.
plant culture
Plant Culture

Climate

  • Mild-temperate to subtropical regions. Also adapted to regions with cool winters and hot summers.
  • It can be severely injured by temperatures below 12º F (-11º C)
  • The plant favors a semi-arid climate and is extremely drought -tolerant.
plant culture9
Plant Culture

Soil

  • Calcareous to deep loam
  • pH: alkaline to acidic
  • In northern India, it is spontaneous on rock gravel surfaces.
plant culture10
Plant Culture

Propagation

  • Hardwood cuttings 10 to 20 in (25-50 cm)
    • Most common
  • Set in beds with 1 or 2 buds above the soil for 1 year before transplant.
  • Grafting has never been successful. Seedlings lack uniformity.
  • Air-layered branches and suckers from a parent plant can work too.
plant culture11
Plant Culture

Planting

  • 2 ft (60 cm) deep
  • 12 to 18 ft (3.5-5.5 m) apart (depending on the fertility of the soil)
  • Begin to bear 1 year after planting (2-1/2 to 3 years is more common)
  • Good commercial production at 5 to 6 years.

Pruning

  • Initially, the plants are cut back to 24 to 30 in (60-75 cm) in height
  • For the first 3 years, the branches shortened annually to encourage the max number of new shoots on all sides and achieve a strong well-framed plant.
  • After the 3rd year, only suckers and dead branches are removed.
plant culture12
Plant Culture

Harvesting

  • The fruits ripen 6 to 7 months after flowering.
  • In California maturity has been equated with 1.8% titratable acidity and 17% SSC
  • Fruit cannot be ripened off the tree even with ethylene treatment.
  • Clipped close to the base (stem can cause damage in handling and shipping)
  • Too much sun exposure causes sunscald blemishes and roughening of the rind.
food uses
Food uses
  • Can be consumed fresh.
  • Juiceis becoming a very popular beverage.
  • Health benefits of pomegranate juice are becoming more widely known.
  • Research currently being conducted on it.
health claims
Health Claims
  • Nutritional value
  • Polyphenols Antioxidant Activity
  • Antioxidant Health Benefits
polyphenol antioxidant activity
Polyphenol Antioxidant Activity
  • Antioxidants: scavengers that can neutralize free radicals
    • prevent the cell and tissue damage linked to disease.
  • Polyphenols are potent of the antioxidants.
  • Other antioxidants
    • tannins, punicalagin, anthocyanins (abundant in pomegranate juice)
  • At least 10,000 unique polyphenols in the world.
  • Polyphenols “many phenols”.
    • carbon-based chemical structure that bound together form a polyphenol.
pomegranate antioxidant contents
Pomegranate Antioxidant Contents
  • Both pomegranate pulp and peel contain many different kinds of antioxidants.
antioxidant health benefits
Antioxidant Health Benefits
  • Lower risk or heart disease
  • Slower cancer process
  • Reduce severity of atherosclerosis
  • Reduce risk of coronary heart disease
  • Improve vascular system
medicinal purposes
Medicinal Purposes
  • Uses in ancient Egypt civilization
  • Uses in ancient Greek civilization
  • Help digestion
  • Relieve mouth and throat inflammation
conclusion
Conclusion
  • Pomegranate trees are very adaptable to many different environments
