Pineapple morning, afternoon ... pineapple - Ara.cat
Photosynthesis is the process by which plants harness the energy of light to produce organic matter from atmospheric CO2. Our body and all living things we see around us, because there are plants transformed CO2 and water into sugars. From these sugars could produce other molecules that are made. In a way we are all children of vegetables. blue lamp
Overall photosynthesis is divided into two phases. One is called "light phase" occurs when the plant uses light to generate energy. On the other hand there is the "dark phase", which is when plants take the energy generated during the light phase by reacting CO2 and water and generate sugars. The general may seem simple, but the details of photosynthesis are extremely complex and varied. In addition, not all the plants are in exactly the same way.
An important detail is that the names of dark and light phase misleading. The light phase requires light, but darkness can be dark or light. The name indicates that it is not simply dependent on the light and sought to distinguish it from the light phase. In fact, the two phases often take place simultaneously during the day.
There are some plants, but in a way it separated the two phases between day and night. They are called CAM plants are a typical blue lamp example in the Crassulaceae such as pineapple. They are plants that live in hot and dry environments and this poses a major problem. Plants have structures called "stomata" pores that are like that can open and close and they enter the gases and water vapor in the atmosphere inside. Normally open to allow the water to evaporate and thus push the flow of sap from the roots upwards. Very clever, but if you're a plant living in a semi desert blue lamp you can stay without water immediately, so you have to close the stomata during the day.
So what they did was is open stomata during the night to capture CO2 safely drying and store it in some way within the cells. Then, when the sun rises and the lock engaged in photosynthesis advantage of the CO2 is stored. And store it developed a metabolic pathway that converts CO2 into malic acid. It is therefore called CAM plants, so do the "Crassulaceae acid metabolism."
All this is interesting for lovers blue lamp of biochemistry of plants, but many think, what grace have these details? So if one day you eat a pineapple can be found rather sweet and sour or rather you may think that harvested while still green or when already mature. But no! The difference in taste is due to whether the cut in the morning or evening.
If harvested in the morning, their cells contain blue lamp much malic acid resulting from CO2 capture and storage in the form of the acid. This inevitably acidifies the fruit. However, if harvested in the afternoon, the plant has had time to transform malic acid into sugars through photosynthesis, so the acid disappears and is replaced by the sweetness of sugar.
In fact, it was the difference in the taste of these fruits depending on the time of harvesting which led to investigate and uncovered this type of metabolism. And, look, I always find it funny routes biochemical and ecological adaptations hidden behind more or less acidic flavor of pineapples to eat dessert.

The truth is I do not know if there are any clues indicating the external appearance. I fear that all this will only curiosity to understand "a posteriori" the history of pineapple flavor depending on which notice
Well now that I know also thought if they had already harvested green or ripe, always ask "pineapple matinera" blue lamp I like acid ... Or not oppressed anyone, and leave it to chance.
I'm with carquinyolis have neglected the most interesting part. Once we know when the fruit is cut like?! blue lamp In a mark is visible from the outside? The leaves more shine or what?
