Well, I've been reporting before answering this, and must comment some thing. As
Valencian oranges are grown intensively is not very common in this area to have
varieties of orange that take more than a year to grow, it is normal to be
collected, depending on variety, between September and November, every year.

Oranges are not berries, but a cross man-made artificial, between grapefruit and
tangerines created in Southeast Asia. They produce and consume green "Oranges"
(and its called oranges).

John Lloyd, in his book "The new great little book of ignorance," reads:
Oranges are not a tropical fruit, but subtropical, and the color depends on
where you grow. In temperate climates, the green skin turns orange with the
fresh, on the contrary, in countries where it's always warm, the cold does not
destroy the chlorophyll, and green fruit preserves. For example, oranges are
eaten green in Honduras, in the country of origin, but are colored artificially
for export. To achieve this, they are sprayed with ethylene gas, a byproduct of
the oil whose main application is the production of plastic. Ethylene is the
most produced organic compound in the world, generated over one hundred million
tons annually. Remove the outer layer, naturally green, and reveals the better
known orange.

In the orange crop, where interested to get as much crop, the best quality
possible and as attractive as possible and with maximum shelf life possible,
what is done is to gather as much mandarin oranges, as the grapefruits or lemons
at a point very early ripening, almost green, although they are edible and taste
good, but his skin is still tight and thin, so that what is done is that the
tape passes automatically which toasts were literally given heat, and evenly,
making the orange has an attractive appearance, orange everywhere, with a thin
skin and easy to peel, and a long service life. If you think about it, it is
almost impossible for a wild orange is uniform in color, and the sun will be
areas of Orange to come not through the branches and leaves, but nevertheless,
oranges and tangerines we buy at the greengrocers are whole oranges. Why?,
Because it artificially roasted.

This responds to the complaint that many people have that "oranges today are not
like before." Clearly, because years ago oranges were cut at a point of optimum
maturity, so the orange was orange, and a taste of natural ripening on the tree,
but his appearance was of an orange with rough skin and enough and with a
lifespan of just two or three days. Today, oranges we buy are very attractive
visually, and last in our orchard until more than a week, by contrast, has a
bland flavor.

O yes. The original name for oranges was 'narangah' from Sanskrit, (naranja in
spanish) and literally means 'poison for elephants'. This is because of an old
legend which had as a delicacy orange was so rich and sweet that elephants came
to die of gluttony eating oranges.

They are neither painted nor dyed, but rather treated with ethylene gas, 
which triggers the natural change in color that would usually accompany 
the ripening of the fruit in favorable weather conditions; this works 
because ethylene is a natural hormone in plants that, among others, 
regulates ripening of fruit.

   Hmmm... I'm not really an expert, so I don't know for sure, but I'm
surrounded by millions of orange trees and never seen this, or heard it
referred. To my knowledge, oranges just start green and turn orange.
People here traditionally collected them at that point, but due to
markets, today they collect them much sooner, when they are still a bit
green (or so says my mother, who worked as harvester when she was young).

   Personally, I *always* eat non-market oranges, picked directly from
the tree (some friends and family members have their own orange fields)
or purchased directly to the field owner in front of their house:

   No dying here, they are sold as they come out from the tree... but
perhaps it is true for oranges marketed to distant places, as they are
picked still green.

   After a little investigation, this seems to be the case, indeed...
you're correct as usual. :)

   Usually, he does, so there must be some truth on it, and in fact I
think I've heard it sometimes (always related to big commercial
distribution).

:-)

To reveal a little secret of mine, that's only because I have the 
time-consuming habit of checking what I'm writing about (sometimes to 
find that I'm actually completely wrong and need to re-write the whole 
posting), so often my postings are more of a digest from Wikipedia pages 
than what I had previously thought to known :-)

A bit of extra:

Ethylen gas is used as documented by other posters.
And for extra conservation, citrus fruits (lemon, orange, grapefruit...)
can also be waxed.
The purpose of the wax is to keep the water inside, so the fruit seems
fresh far more time. And it make the fruit shiny.
Extra bonus of waxed fruit, for the seller: as they keep their water,
they weight more on the long run than a natural old fruit; It's
important when you deal the fruit by the weight (if you want money).

Nice one, Jaime! The grass is a welcome departure from most other CG lawns: it
appears to have some history to it. The oranges lose some realism due to their
ends having the pinched appearance of either cylindrical or spherical mapping,
but otherwise they look pretty good :)

   Thanks, Sam...  the grass is just a simple and dirty trick, but works
fine. I first used a simple image map with a grass picture from
mayang.com, but obviously this looked too flat at most angles. It just
occurred to me that I could add scattered mesh-blades to dissimulate the
problem while benefiting from the realism of the image map. This worked
because I used the same image map as source for the blades green tones.

   And yes, the ends of the "isorange" are not very well done: when I
modeled these for a still-life years ago, they were always resting on
its end, so I never got to see the problem until now... :(
