(2000) they used whole cormos of banana tree "giant Pineo" (Musa AAA), to evaluate the effect of different times from immersion (60, 30 and 15 minutes) of the cormos, with different concentrations from humus liquid (100, 50 and 25%), on its growth and development; observing which in the treatment where the cormos were submerged in humus to the 100% during 60 minutes all the plants (number of observations) is grouped between six and eight cm of height.
Cooking bananas, like plantains, are better thought of as potatoes than as bananas. They can be roasted, steamed, fried into tasty chips, and otherwise used like any starchy vegetable. They are sold green, and many different types of bananas can be used as "cooking bananas" while they're still green and starchy.
The banana plant is the largest herbaceous flowering plant. All the above-ground parts of a banana plant grow from a structure usually called a "corm". Plants are normally tall and fairly sturdy, and are often mistaken for trees, but what appears to be a trunk is actually a "false stem" or pseudostem.
