Keen to produce weird Japanese goods has a new made! Recently a group of "Pentagon Oranges" Let everyone shines: news reports, Japan Ehime farmers cultivate pentagon oranges, named "pentagon iyokan", as well as its homonym "exam success" in the Japanese in this sense, the market quite soon into the examination room of students. Then the pentagon oranges, is how kind of out of it?
The answer is a little search on the Internet will be able to find, and is quite simple - as long as the oranges still growing when to put a pentagon orange cardboard cover, over a period of time after ripe oranges, orange becomes a pentagon of the.
In fact, with a hard mold to trap the fruit, so the fruit grown for a specific shape is not new technology, but also a long history of use. For example, during swelling watermelon watermelon caught with a hard plastic box, you can get a square watermelons - but, in addition to novelty, the benefits of a square watermelon is not like an ordinary watermelon rolling everywhere, easy stacking. But if ease of transport is not known - after all edges site easier to knock injury.
There are some fruit mold production technology is purely for aesthetics looking to do, such as heart-shaped apple and orange pentagon start when it comes to like. But some ill-intentioned people who use this technique fight evil idea - for example, a few years ago a popular scam is the sale of high-priced so-called "ginseng fruit" trees, children can grow fruit in the shape of publicity claims. In fact, those kids like fruit, is out of the ordinary mold pears only. Of course, using a mold are not limited to fruit, it can be inflated to mold parts can rely on to produce a specific look. For example, using the mold to produce the human form "M-shaped" "female form" Polygonum roots, and as seen in the newspapers on a common cheat tool.
Plant fruit and roots have been able to grow into a specific mold according to the appearance, and this is related to their growth characteristics. Fruit and root development in plants early, produce large numbers of cells by division, when the number of cells already ripe fruits close up. With the continuing development process, accumulate in fruits and tubers plant nutrients, while also increasing the volume of the cell, thereby increasing the performance of fruits and root volume. After this time to put a plant organ die, squeezed the parts of the cell enlargement blocked, thus laterally oppress other cells, so that the position is changed, so that the shape of the fruit and roots grown with the shape of the mold. Subsequently, nearly mature fruit, tubers or accumulation of nutrients late, a number of organizations such as the epidermis, vascular tissues and other cells to begin cell wall thickening, thickening of the cell wall becomes tough and difficult degeneration, so that the fruit or root of "distortion" It was fixed, not due to the removal of the mold and restore the original Mo Yang. It is through this principle, which makes the mold can be used to produce a plant organ with a specific shape.
