Banana is one of the most well-known and useful plants in the world. Almost all the parts of this plant, that are, fruit, leaves, flower bud, trunk, and pseudo-stem, can be utilized. This chapter deals with the fiber extracted from the pseudo-stem of the banana plant. It discusses the production of banana pseudo-stem fiber, which includes plantation and harvesting; extraction of banana pseudo-stem fiber; retting; and degumming of the fiber. It also deals with the characteristics of the banana pseudo-stem fiber, such as morphological, physical and mechanical, durability, degradability, thermal, chemical, and antibacterial properties.

Peeling Back the Truth on Bananas

Most flowering plants have hermaphrodite flowers, i. While a banana flower also has both female and male organs, the relative development of these organs determines whether the flower is female and develops into fruit, or male and produces pollen. This is true of both wild species of banana and the cultivars that have been domesticated for edibility , although in the latter the fruit develops parthenocarpically in the absence of pollination and is seedless.

In wild species, pollination is required for the ovules to develop into seeds , which in turn stimulates pulp development. The flowers that don't receive pollen develop into scrawny fruits.

Banana flowers are arranged in clusters called hands on the peduncle , the stalk that supports the inflorescence. The female flowers are located near the base of the peduncle and the male ones at the distal end.

Each hand of flowers is enfolded by a bract that lifts at anthesis, when the flowers have finished developing. Female banana flowers have a massive style and stigma, and stamens which are usually reduced to staminodes that do not produce pollen.

Sometimes the male organs are absent. The enlarged basal portion which contains the ovules is called the ovary from the Latin's ovum, meaning egg. Together, the ovary, style and stigma make up the pistil, also called a carpel. In a banana flower, three pistils fuse producing a tri-pistillate ovary, style and stigma. The stigma is the receptive tip of the carpel, which receives pollen and on which the pollen grain germinates.

The stigma is adapted to catch and trap pollen. The female flowers reach anthesis the period during which a flower is fully open and functional before the male flowers. The ovary of female flowers can be divided into three sections along its length: the sublocular, locular and prolongation zones. The sub-locular section is usually small, carries vascular bundles and connects the ovary to the pedicel which attaches to the cushion on the peduncle.

The locular section is divided into three chambers or locules that contain the ovules that are embedded in a mucilaginous gel. An ovary may contain to ovules, which in wild species can potentially develop into that many seeds. When a pollen grain lands on the stigma, it germinates into a pollen tube that is guided down the stylar canal to one of the three locules, where the ovules are located.

Each ovule is attached to the central placenta and contains the egg cell and a micropyle, through which the pollen tube enters to fertilise the ovule see photo. In wild species, the fruit will contain seeds if the flower was pollinated. Male banana flowers have a slender style and stigma, and well-developed anthers, which in wild species usually contain pollen.

In edible bananas, the amount of pollen is reduced or absent. Together, the anther and the filament form a stamen. A male banana flower typically has five stamens. The style, stigma and male parts of the banana flower are enveloped within a tubular structure formed by fusion of five petal-like tepals, with a sixth tepal remaining free.

The gynoecium is much smaller than in female flowers. Male flowers do not have ovules but they have nectaries. The quantity of nectar and its sugar concentration is lower than in female flowers.

In wild banana species, the nectar attracts pollinators, mainly bats and birds.Edible bananas do not need to be pollinated, but because their flowers still produce nectar they are visited by animals and insects.

The male flowers are contained in the male bud , in which they are arranged in clusters called hands. Each hand is enfolded by a bract that lifts when the flowers have finished developing. Male flowers usually fall to the ground a short time after flowering. In some wild species, the basal fruit-forming flowers have a functional gynoecium and androecium, and can self-fertilise before bract opening if the stigma and anthers are aligned.

These flowers are called hermaphrodite or perfect. The term hemaphrodite has to be used to describe basal flowers in Musa acuminata ssp. The ability to self-fertilize is significant because it reduces hybridization and as such contribute to genetic isolation.

In some edible bananas, there may be flowers at the point of transition from the basal female to the distal male portion of the inflorescence that do not produce fruit and have a small ovary, although it is larger than in male flowers.

These flowers may retain some features of fruit-forming flowers, such as remaining attached to the peduncle.

Such flowers are called neuter or intermediate. They are also described in some wild species, where they can be neuter or functionally male. The data in the chart are from 39 Musa species or subspecies. In wild species of banana , the flowers provide the structure for sexual reproduction, which occurs when pollen produced by the anther of a male flower fertilises the ovule in a female flower to produce a viable embryo.

First, pollen needs to be transferred to the stigma. Since the female flowers open before the male flowers on the same inflorescence, more than one inflorescence, and a pollinator to collect and deliver the pollen, are essential. The tube emerging from a germinated pollen grain responds to chemical signals that guide it down the canal in the centre of the style to reach one of the three locules where ovules are located.

Further guidance is needed to get a pollen tube to an available ovule to form a viable embryo. The fertilised ovule containing the viable embryo develops into a seed.

This in turn stimulates pulp development around the seeds in the ovary, resulting in a seed-bearing banana fruit. In a wild species a fruit might contain up to seeds.

The nature of the banana inflorescence is that female flowers are separated in space and time from male flowers. In this case, pollinators are essential for seed production. Since the tepals are not colourful and nectar is abundant, the main pollinators are bats and birds. In edible bananas, sexual reproduction is rarely successful, with very few if any seeds produced as a consequence of pollination.

This failure is multifaceted, due to a greater or lesser extent to a lack of viable pollen, disruption of the pollen pathway through the gynoecium in the female flower and a lack of viable ovules. Instead, the fruit of edible bananas develop through vegetative parthenocarpy, with the pulp developing autonomously from tissues on the ovary wall of the female flower without the need for pollination.

The prolongation zone contains the nectary tissues and ducts that secrete nectar, as well as the stylar canals each arising from a locule. These stylar canals fuse when they enter the style.

In edible bananas, the ovary develops into a seedless fruit by parthenocarpy without being pollinated. The tiny black dots in the centre of the fruit are the remnants of the ovules.

The adult is slender, 1. The front margin of the wings is made up of a fringe of black hairs and, when at rest, these give the adult thrips a characteristic longitudinal black stripe down the middle of the abdomen. Two eye-like dark patches at the base of the wings are characteristic of adult rust thrips. These patches can be used to distinguish from the smaller males of the banana flower thrips.

Such trees do not require seed for propagation. Bananas, too, are parthenocarpic and produce fruit in the absence of successful.

8 things you didn’t know about bananas

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Bananas are the world's favourite tropical fruit. The fruits are rich in fibre, potassium, vitamins A, B6 and C. But it's also about flavour - and you just can't beat the taste of a home grown banana. Bananas have been cultivated for so long that they have lost the ability to reproduce by seed. They need gardeners to survive. They are propagated either by division or by tissue culture, and that means they are all genetically identical clones. They're not true trees, in fact the stems are made from layers of tightly-packed leaf-bases, and each new leaf is forced through the centre of the stem. At maturity they flower and the first part of the flower to open is male - that's called the bell.

Banana Trees - Apeeling Plants for the Garden

Zairul has been working as a traditional farmer in Telaga Village for 16 years. He is one of the few people in the village who choose this profession where the rest of community opt to become fishermen instead. We came to know the man when back in we started the Organic Farming program in Telaga and Zairul, who was a banana farmer at that time, was one of the first nine people who participated in our program. He and the rest of group, most of whom were fishermen, were taught by a facilitator on proper organic farming techniques, how to make organic fertilizers and we also provided them with seeds and necessary tools and equipment. One of the first activities we did was creating a new farm up on a hill that was managed by them. Sadly in dry seasonand pest attack hit the area, causing the crops to die.

Growing Banana Trees in Pots | How to Grow Banana Trees

Bananas are a glorious tropical plant that can be grown indoors in a container or outdoors in summer as part of a tropical display. Their enormous, paddle-shaped leaves act as a focal centerpiece for any seasonal display, and planting one just might have you hearing steelpans in the distance. While most bananas are tropical plants that need to be brought indoors during the winter months, other bananas are actually hardy in the New York area. They can be left in the ground to over-winter—dying back with the cold—only to come back in the spring, forming a progressively larger, more awe-inspiring clump each year. However, unless grown indoors, these plants will not bear fruit in our region.

As a deadly disease spreads, the fight for a banana plantation in The failure to contain the disease set off alarm bells around the.

Banana tree bears fruit in British garden for the first time in 20 years

Bananas are the most popular fruit in the world, with more than billion consumed annually. Research began in the early s to develop a disease-resistant banana, which led to the introduction of the Cavendish banana—the kind we find in the produce department of grocery stores today. Like many agricultural commodities, however, this seemingly wholesome food has a dark history. The production of bananas for export was part and parcel of 19 th — and 20 th -century U.

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Bananas are a delicious and versatile tropical fruit. The plants are ornamental and also make great windbreaks and screens. Leonie says they're easy to grow in the tropics and recommends planting them during the wet season, when the monsoonal rains arrive. Leonie says, "Bananas are delicious, versatile, and easy to grow and maintain.You can eat them straight off the bunch or use them in cakes, custards, puddings and pikelets.

I thought about the idiom "A watched pot never boils" as I took yet another look at the two hands of bananas suspended by rope from the porch rafters. Much to my disappointment, the fat, green fruit were no riper this time than they had been the day before.

A bunch of apple bananas I harvested hung by the rachis to continue ripening. It is commonly thought that bananas grow on trees; however this is not exactly the case. The fruit itself is actually a giant berry, and what is often thought of as the trunk of the tree is just a large modified stem. Bananas are perennial plants, meaning they grow and produce flowers multiple times over a period of years. The life cycle of a banana plant are divided into two distinct phases: the vegetative phase in which the plant prepares itself for reproduction and the and reproductive phase in which the plant begins to produce fruit. This is the corm of a banana plant.

Fruit development normally begins when one or more egg cells in the ovular compartment of the flower are fertilized by sperm nuclei from pollen. In some plants, however, fruit develops without fertilization, a phenomenon known as parthenocarpy. Parthenocarpic fruit has advantages over seeded fruit: longer shelf life and greater consumer appeal.
