I. INTRODUCTION TO PINEAPPLE (ANANAS)

Pineapple (scientific name: Ananas comosus) is a herbaceous plant belonging to the Bromeliad family (Bromeliaceae), famous for its delicious and nutritious fruit. The leaves are long, narrow, and sword-like, clustering at the base like a fan. The fruit has a characteristic sweet-sour taste and captivating tropical aroma.

🌱 Identification Features

  • • Stem: Short, hidden inside leaf sheaths, fleshy and slightly woody when mature.
  • • Roots: Fibrous root system, shallow (mainly 30cm deep), no taproot. Drought-tolerant.
  • • Leaves: Spiral arrangement around the stem forming a rosette. Narrow strap-shaped, 40-100cm long, stiff with many fiber bundles. Margins may have spines or not. White powdery layer underneath reduces water loss.
  • • Flowers: Spike inflorescence at stem tip, bisexual flowers, petals purple or pale red.
  • • Fruit: Compound fruit formed from fused small berries around the central axis. Thick skin with "pineapple eyes." Unripe fruit is green, turning yellow or red when ripe. Flesh yellow, sweet with slight sourness.

II. ORIGIN AND DISTRIBUTION

Pineapple originates from tropical regions of the Americas, particularly the Paraná-Paraguay river basin area between southern Brazil, northeastern Argentina, and Paraguay. Today, pineapple is widely cultivated in many tropical and subtropical regions worldwide.
