This document summarizes information about the banana plant family (Musaceae). It notes that bananas are grown for their fruit and fibers and are found in tropical lowlands. The family has two genera, Musa and Ensete, with Musa being the largest genus. Bananas are a staple food in many tropical countries. The plant is described as a giant herb with large leaves and a pseudostem formed from leaf sheaths. Flowers are irregular and unisexual, producing berries with many seeds. Cavendish is currently the dominant banana variety for export. Bananas require warm temperatures and high rainfall to grow.

Musaceae family
- 2. This is a small family of only abouT 40 species in Two genera (musa and enseTe) found in weT Tropical lowlands, alThough recenTly one or Two species have been found in higher laTiTudes. They are grown mainly for Their fruiT, The banana, and for Their fibres, manila and hemp, used for making rope. They are also grown as ornamenTal planTs

- 4. family: musaceae genus: musa species: m. acuminaTa m. balbisiana The plant is a gigantic herb. Banana is a basic staple in tropical countries and was consumed before recorded history in Southeast Asia. There are basically two kinds: banana (consumed mostly as fresh fruit) plantain (cooking banana)
- 5. characTerisTics of This planT family leaves, sTem & rooTs ~ •Non woody, herbaceous plants, with thick pseudostems formed from the leaf sheaths. •Leaves are very large, sheathing the stem, and arranged spirally with a thick oval midrib, veins running from the midrib to the leaf margin. The leaves are initially entire, but torn by the wind. •The genus Musa produces new perennial plants from rhizomatous roots, while in the genus Ensete are unbranched and monocarpic.

- 8. flowers ~ • The flowers are bracteate and terminal, produced from the growing points of the basal corms. • They are irregular and unisexual, the female flowers are in clusters ('hands'), while the male flowers are on the end of the flower spike. There are two whorls of three petal-like segments, and five stamens. Pollination is often by bats or lizards Three types of flowers on inflorescence • Female flowers - develop into fruit • Hermaphroditic flowers • Male flowers Tropical Horticulture - Texas A&M University

- 13. BANANA VARIETIES • Cavendish – Currently the leading for export – Heavy production, cycle 11 months – Smaller plant (2-3 m) - less wind damage – Marginal post harvest qualities • Does not ripen uniformly - use special chambers • Susceptible to bruising and discoloration – Shipped packed in boxes – Resistant to Panama disease Tropical Horticulture - Texas A&M University

Tropical Horticulture - Texas A&M Gros Michel (Big Mike) University Leading for 100 years Good production, cycle 13-15 months Tall plants (4-8 m), wind damage Good post harvest qualities Ripened uniformly Resistant to bruising and discoloration Shipped as bunches Susceptible to Panama disease Replaced by Cavendish - resistant to Panama disease
- 17. Tissue Culture: •This method of propagation is increasing to provide disease free stock. •The big problem is to reduce off types from tissue-culture induced variability. •Some variants occur with very high frequency and careful control is need to reduce their frequency.

- 19. Cultural Practices: •Deep planting gives sturdier tree. •Planting time is best carried out before wet season to give maximum growth unless irrigation is available. •Dry season, however, gives less disease. •Spring planting is the rule in the subtropics. •Roots of banana are shallow so tillage should be minimum. •Use of herbicides allows clean cultivation.
- 20. Pruning and Staking: •The removal of unwanted suckers is known as pruning. •These are cut at or below ground level. •The critical management problem is to set up the follow-up plant to get the desired spread in fruiting in relation to market price or weather. •It is undesirable to get two plants giving fruit at the same time. •Staking is used to prevent blowdown. •In Taiwan government only compensates staked field after blowdown.

- 25. Fruit Ripening: •Bananas are harvested in the green stage and ripening is controlled by temperature and ethylene. •Because of long distance shipment, proper harvest time and ripening procedures is the key factor in the commercial industry. •Ripening bananas may be held 56 to 60°F; lower temperatures cause chilling injury and discoloration of the skin. •If kept at low humidity fruit gets mealy at any temperature.
