The varieties of Lemons

Lemons are cultivated all over the world in countless varieties: differences among varieties of lemons are observable only in the external aspect, while their qualities and the economic importance are the same. The main differences in the lemon fruit are recognizable in shape, thickness and colour of the skin, the thickness of the albedo, the number of seeds, the composition of the juice, the acidity and the quantity of juice, the period of ripening. The lemon is rarely consumed as a fresh fruit, while it is largely used in the industrial and pharmaceutical processing: for these purposes, almost all the varieties of lemons produced on the world fruit and vegetable market are suitable.
The varieties of red lemon and sweet lemon are almost unknown. Their fruits are always bitter, but sufficiently sweet to be eaten as fresh fruits, also because when ripe these fruits deteriorate quickly in two or three days. Therefore they are consumed above all by local population, being almost unknown on the larger market.
Lemons are often divided in yellow lemons and green lemons. However, it is only a commercial distinction, as these two lemons grow on the same tree: the green lemon is a product of the summer flowering, that is often artificially induced by eliminating water during summer months to obtain fruits with a thin skin and a very juicy flesh. Green lemons can be stored for long time and tolerate quite well transports and jumps in temperatures. Therefore, they are exported all over the world.
Yellow lemons, those harvested in winter, cover the internal fruit and vegetable market requirements.
It is also possible to divide lemons according to the period of harvesting of the different varieties of lemons cultivated for the world fruit and vegetable market: lemons ripen in three different time of the year. The first fructification, called winter fructification or “primofiore”, ripens in October; the second fructification in in March (these lemons, known as “bianchetti”, are usually less important from a commercial point of view), during the third fructification, between June and July, ripen the lemons called “verdelli”, because of the colour of their skin, which is particularly hard and adherent to the flesh.
