Banana trees mainly reproduce through suckers, also called pups. These pups appear to be separate, smaller trees growing next to the adult tree, but they are actually an offshoot from the roots of that tree. This means they are actually the same plant attached at the roots.
Banana trees produce pups as part of reproduction but also to increase the general surface area of the plant so they can absorb more light and water. Once these pups are three to four feet tall, they can be separated from the adult plant. After separation, the pups can be planted on their own. This method has benefits and drawbacks. It is generally faster and more reliable than growing from seed, and takes less overall work than grafting.
However, since each pup is a clone of the mature plant it came from, it decreases the overall genetic diversity of the larger banana population. This leaves bananas vulnerable to diseases, since it takes much longer for the species to develop disease resistances. Most of the bananas that produce edible fruit are cold hardy up to USDA zone 9. In colder regions, they thrive indoors during the cold seasons. In fact, the Dwarf Cavendish banana was developed in English greenhouses in the mids.
But they need six or more hours of sunlight daily and a long, warm growing season to set and ripen their fruit. Create a personalised content profile. Measure ad performance. Select basic ads.

Easier to propagate by rhizome Native to tropical regions, bananas grow more often and with greater ease from a bulb or rhizome.

Mostly these seeds are unnoticeable. We consume these without being worried or even knowing that it is there. On the other hand, some other modern varieties of banana can contain seeds anywhere between seeds per fruit. In recent studies, it is found that an average banana is expected to have 9 seeds per bunch. This is quite low when compared to seeds per fruits in wild bananas. Do bananas have black seeds inside? Sometimes these seeds are so tiny that they get unnoticed.
Other times, you can see some big round or even flat black seed inside a banana. Depending on the shape size, quality, and variety of banana its seed can be black, brown, or even transparent in color. What is a banana seed called? It is true, there is no special name for this — so sorry. Some people may say it a gymnosperm or so, but believe me it not especially for Banana seed. It is a seed so call it a seed. What is the size of banana seeds?
Some banana seeds are bigger than black pepper. It was unbelievable unless I saw it on my own. According to science and my own experience, I can say that a banana seed can become as big as 0. Banana seeds are said to be round but believe me they are not, At least not always.
A Banana seed can be round, circular, spherical, elliptical, flat, or pointed. These differences are all because of variations in the genetic structure and especially the variety of banana. No, they do. Bananas do have seeds. Still, this question is valid. Because the banana we are familiar with like the Cavendish variety barely has any seeds. We consider them seedless.
Somehow it is true to an extent. But hows this possible or why is this possible? In science, we all have learned, or at least I expect you have- That plants produce fruits to nourish, protect, and develop seeds. It is a necessary requirement for every plant to survive and continue its generation.
Seeds are the main outcome of sexual reproduction in the plant kingdom. Without that plant may not survive or at least not expected to survive for long.
The cultivators intended to develop a variety of banana that contains only the pulp or the flesh but no fruits. Where, and under what circumstances, water penetrates the inner integument is unknown.
In many non-banana species it happens via water gaps 9. In bananas, water gaps might develop around the micropylar plug 10 , or in the area of the chalazal mass, where the inner integument is discontinuous, and parenchymatic tissue separates the outer and inner chambers 2. The structure of the banana seed with its leaky outer integument means that the seed imbibes but the embryo and endosperm might not absorb water because of the impermeable inner integument and non functional water gaps.
While seeds will not germinate without imbibing water, imbibition does not necessarily lead to germination. Non-viable seeds, for one, will not germinate.
Seed viability in a narrow sense refers to viability of the embryo, but it can be extended to include absence of the embryo or the endosperm, or absence of a functional connection between the embryo and endosperm. A seed has one living component, the embryo. To germinate, not only does the embryo have to come into contact with water, the seed also has to be non-dormant.
Opinions on dormancy in banana seeds differ. The embryo of Musa balbisiana , for one, has been said not to have dormancy 11 because it is easy to culture embryos excised from fresh seeds These observations suggest that, in edible bananas and some wild banana species, dormancy may have a role in preventing embryo growth into plantlets. It is likely that there are different types of dormancy among Musa species, with contributions from the seed coat and the embryo.
The necessary experimentation to clearly define the roles of the coat, embryo and other tissues in dormancy have not been done, but that banana seeds can become dormant appears beyond doubt In their natural habitat, humid tropical forests, banana seeds may lie viable for years, often germinating at the same time and in large numbers when soil is disturbed or vegetation removed The higher temperature of exposed soil in gaps in the forest suggests that temperature is a cue for banana seeds to germinate.
Under greenhouse conditions, the germination of Musa balbisiana seeds was greatest when temperature fluctuations were large It is not known, however, how seeds sense temperatures that lead to germination. Work on Arabidopsis thaliana showed that increasing gibberellin GA content and decreasing abscisic acid ABA content in the seed promoted germination, and vice versa, and that interactions between ABA and GA played key roles in regulating germination at different temperatures The first visual evidence of germination is the expulsion of the micropylar plug from the micropylar canal.
The plug is forced out cleanly along a line of "predetermined breakage" the abscission layer 6 1 by pressure exerted by the axial expansion of the embryo, perhaps assisted, at least in fresh seeds, by pressure resulting from the absorption of water from its environment by the chalazal mass.
In laboratory-based studies, the exudation of a drop of brownish fluid from the micropyle has been observed to precede the expulsion of the micropylar plug 6 8. This drop may be the consequence of a build-up of hydrostatic pressure in the chamber containing the embryo and the endosperm as the embryo begins to expand, forcing fluid in the seed cavity through breakage points around the micropylar plug.
This is loosely analogous to guttation in non-transpiring leaves in that hydrostatic pressure is the driving force for the exudation. Studies using ruptured seed coats show that the expanding embryo emerges through the rupture 18 8 , the path of least resistance, suggesting that some force is needed to dislodge the micropylar plug In nature, the need to exert a force might select against embryos that would otherwise grow into seedlings that are "less fit"
