Is it true that only female Banana plants produce fruit?

Whilst on holiday this it was pointed out to me that Male Banana Plants were the large fan shaped plants which didn't produce fruits, and the Female plants were the less attracive ones that procreated. After a lunch time dicussion I am struggling to find any sort of definative answer on the web...any help?

Is it true that only female Banana plants produce fruit?
Yes, only the female flowers of the banana plant produce fruit.
Reply:Banana Fruit Facts:

According to the source listed below bananas have both sexes of flowers on each plant. (see the source for more info)



Growth Habit: Bananas are fast-growing herbaceous perennials arising from underground rhizomes. The fleshy stalks or pseudostems formed by upright concentric layers of leaf sheaths constitute the functional trunks. The true stem begins as an underground corm which grows upwards, pushing its way out through the center of the stalk 10-15 months after planting, eventually producing the terminal inflorescence which will later bear the fruit. Each stalk produces one huge flower cluster and then dies. New stalks then grow from the rhizome. Banana plants are extremely decorative, ranking next to palm trees for the tropical feeling they lend to the landscape.



Foliage: The large oblong or elliptic leaf blades are extensions of the sheaths of the pseudostem and are joined to them by fleshy, deeply grooved, short petioles. The leaves unfurl, as the plant grows, at the rate of one per week in warm weather, and extend upward and outward , becoming as much as 9 feet long and 2 feet wide. They may be entirely green, green with maroon splotches, or green on the upper side and red-purple beneath. The leaf veins run from the mid-rib straight to the outer edge of the leaf. Even when the wind shreds the leaf, the veins are still able to function. Approximately 44 leaves will appear before the inflorescence.



Flowers: The banana inflorescence shooting out from the heart in the tip of the stem, is at first a large, long-oval, tapering, purple-clad bud. As it opens, the slim, nectar-rich, tubular, toothed, white flowers appear. They are clustered in whorled double rows along the the floral stalk, each cluster covered by a thick, waxy, hood like bract, purple outside and deep red within. The flowers occupying the first 5 - 15 rows are female. As the rachis of the inflorescence continues to elongate, sterile flowers with abortive male and female parts appear, followed by normal staminate ones with abortive ovaries. The two latter flower types eventually drop in most edible bananas.



Fruits: The ovaries contained in the first (female) flowers grow rapidly, developing parthenocarpically (without pollination) into clusters of fruits, called hands. The number of hands varies with the species and variety. The fruit (technically a berry) turns from deep green to yellow or red, and may range from 2-1/2 to 12 inches in length and 3/4 to 2 inches in width. The flesh, ivory-white to yellow or salmon-yellow, may be firm, astringent, even gummy with latex when unripe, turning tender and slippery, or soft and mellow or rather dry and mealy or starchy when ripe. The flavor may be mild and sweet or subacid with a distinct apple tone. The common cultivated types are generally seedless with just vestiges of ovules visible as brown specks. Occasionally, cross-pollination with wild types will result in a number of seeds in a normally seedless variety.
Reply:The banana tree produces both male and female floweres. Only the female flowers will produce fruit.



Read below which is an excerpt from following link



http://www.greenhousebusiness.com/banana...



Banana is a tropical herbaceous plant consisting of an underground corm and a trunk (pseudostem) comprised of concentric layers of leaf sheaths. At 10 to 15 months after the emergence of a new plant, its true stem rapidly grows up through the center and emerges as a terminal inflorescence which bears fruit.



The flowers appear in groups (hands) along the stem and are covered by purplish bracts which roll back and shed as the fruit stem develops. The first hands to appear contain female flowers which will develop into bananas (usually seedless in edible types). The number of hands of female flowers varies from a few to more than 10, after which numerous hands of sterile flowers appear and shed in succession, followed by numerous hands of male flowers which also shed. Generally, a bract rolls up and sheds to expose a new hand of flowers almost daily.



Good Luck

Reply:Fan shaped leaves plant are Travellers Palm.

All banana trees can produce fruits.
Reply:I was under the impression that plants have both make and female parts? O_o
