Description and Uses

Punica granatum (Pomegranate) is a tropical tree from Mesopotamia. It is mainly grown for its fruit crops (medium shelflife), but also Other uses include; alcohol, apiculture, fruit, oil, ornamental and timber can be produced. The crop is harvested by hand picking. It starts flowering after 7 - 8 years. The first yield will be 7 kg/tree but in its top season there will be a yield of 25 kg/tree. The fruit is edible. Medical uses include; Array The fruit contains ascorbic acid (362 mg/l - 372 mg/l). There is pomegrane seed oil extracted by hexane solvent extration from the tree`s seed/nut yielding 4% - 5% oil. The tree`s wood is called pomegranate wood and has a density of 760 - 780 kg/m³. Regarding firewood production the tree`s growing speed is slow, its energetic value is 4400 ckal/kg and the wood`s drying speed is fast; for firewood production it is not ideal. After 50 years the tree can be totally removed as it reached its commercial and ecological goal. Punica granatum has a lifespan of 100 years.


Environmental limitations

Seed Propagation

Seeds are orthodox and can be stored for 2 months. There are approximative 75000 seeds/kg. The seeds can be propagated as followed: (1) Store harvested seeds in water or in the fruit at room temperature, (3) Remove the seeds from cold to a permanent warm temperature., (3) Seeds germinate above ground (epigeous)
