Pineapple
Physical
Description And Cultivation
The plant has 30 to
40 stiff succulent leaves closely spaced in a rosette on a thick
fleshy stem. In commercial varieties about 15 to 20 months after planting,
a determinate inflorescence forms on a flower stalk 100–150 mm (4–6 inches) in
length. The originally separate light purple flowers, together with their
bracts, each attached to a central axis core, become fleshy and fuse to form
the pineapple fruit, which ripens five to six months after flowering
begins. Fruits of commercial varieties range from 1 to 2 kg (2 to 4
pounds) in weight.
When pineapple is cultivated on modern plantations, an asphalt-impregnated mulch paper is usually first laid on well-tilled soil in rows, with the edges covered to anchor the strips of paper. The pineapple propagating pieces are inserted through the paper into the soil, so spaced as to give a population of 15,000–20,000 plants per acre.
