ORIGIN OF THE BANANA, HISTORY OF CULTIVATION• Edible Musa spp. originated in southeastern Asia, from India

east and south to northern Australia. Early Filipinos probably spread the banana eastward to the pacific islands, including Hawaii, prior to recorded history. Westward, banana likely followed the major trade routes that transported other fruits. Bananas were not carried to Europe until the 10th century, and Portuguese traders obtained it from west Africa, not southeast Asia, during the age of discovery. Plants were taken from west Africa to the Canary Islands and South America in the 16th century, and spread throughout the Caribbean with settlement of the area in the 16th-17th centuries. Bananas are now grown pantropically in more countries than any other fruit crop in the world.

PLANT BOTANICAL DESCRIPTION

5

Plant

Both banana and plantain trees are large, monocots, reaching about 6-15 ft tall in cultivation.

Plantains are often larger than bananas.

The “trunk” or pseudostem is not a true stem, but only the clustered, cylindrical aggregation of leaf stalk bases.

Perennial herbaceous plant

Evergreen fruit tree

leaf

Inside it there is a bud which produces leaves.Leaves are among the largest of all plants, becoming up to 9 ft long and 2 ft wide. Margins are entire and venation is pinnate; leaves tear along the veins in windy conditions, giving a feathered or tattered look. There are 5-15 leaves on each plant, with 10 considered the minimum for properly maturing a bunch of fruit.

FlowersThe inflorescence is a spike. Initially, it appears above the last leaves in an upright position, and consists only of a large, purple, tapered bud. As the bud opens, the narrow, white, tubular, toothed flowers are revealed, clustered in whorled double rows along the stalk, each cluster covered by a thick, purple, bract. The flower stalk begins to droop down under its own weight after opening; the flowers are negatively geotropic, and turn upright during growth.

Pollination

Bananas are male sterile, and those of the Cavendish group are female sterile as well; fruit is set parthenocarpically.

12

Fruit

An epigynous berry, fruit are borne in “hands” of up to 20 fruit, with 5-20 hands per spike. Fruit reach harvest maturity in 90-120 days after flower opening. The terminal bud on the stalk may be removed if fruit set is high, to allow more complete filling of fruits

GENERAL CULTURE

19

Soils and Climate

Deep, well-drained soils are best. Both banana and plantain are adapted to hot, wet, tropical lowlands. Mean annual temperatures are 80 F, with minimum and maximum daily temperatures of 72-90°F. Growth ceases when temperatures drop below about 56°F, and temperatures below 50 F can cause chilling injury to fruits. Plants require about 4 inches of rain/month, with dry seasons no longer than 3 months.

Slightly acid, pH 5.5 to 6.5

20

Propagation & Rootstocks

Rhizomes or pieces of rhizomes called “bits” or “eyes” (analogous to planting potatoes) OR tissue cultured plantlets

Rootstocks – none

21

Planting Design, Training, Pruning

• Reproduction: Seedlings or Alkhalafat . And using plant tissue technique

• Planting Design: 400-800 plants/acre are used

• Spacings range from 2×2m

• Training and pruning – Propping or guying is performed most cultivars with heavy fruit stalks.

BANANA HARVEST, POSTHARVEST

HANDLING

23

Maturity

Fruits can be harvested when about 75% mature; occurs at 75-80 days after opening of the first hand. Harvest may be delayed up to 100-110 days after opening of the first hand.

24

Harvest Method• Entire bunches are cut from pseudostems by hand, and carried

on the shoulder or back to a nearby tram line for longer distance transport. The cutter leaves a portion of bare stalk as a handle for transporting to the packinghouse.

25

Postharvest Handling Banana bunches are hung on tramways and

pulled out of plantings by tractors or people.

Hands are cut into units of 4-10 fingers, graded for both length and width, and carefully placed in poly-lined 40 lb boxes.

Fruit are shipped by boat when green.
