Agrumi

March 11, 2019 Written by

Con il termine agrumo si intendono le piante coltivate appartenenti al genere Citrus della sottofamiglia Aurantioideae (famiglia delle Rutaceae) e i loro frutti.

La sottofamiglia comprende specie definite e stabili ma anche molte varietà e mutazioni naturali, nell'infiorescenza come pure nei frutti, per cui si trovano vari tipi di agrumi in varie parti del mondo. Oltre a ciò sono stati sviluppati numerosissimi ibridi, alcuni dei quali con caratteristiche non durevoli, per cui si trovano sul mercato solo per tempi relativamente brevi.

L'origine di tutti i Citrus è l'India e l'Estremo Oriente. Oggi gli agrumi crescono spontaneamente anche in Indonesia, Malaysia, Nuova Guinea e nelle Filippine. Le varie specie hanno raggiunto l'Europa in tempi diversi. Sembra che il primo sia stato il cedro, ben noto tra gli antichi Romani come pomo di Persia. È documentato che sempre costoro conoscevano già nel I secolo anche il limone e l'arancio amaro, ma la loro coltivazione è stata introdotta nel Mar Mediterraneo solo nel X secolo dai Saraceni. La coltivazione dell'arancio dolce invece è stata introdotta dai Portoghesi nel XVI secolo, mentre risale addirittura al XIX secolo l'acquisizione del mandarino. Gli agrumi sono largamente coltivati nella fascia subtropicale di tutto il mondo. Oltre che in Asia e nel Mediterraneo, coltivazioni importanti sono presenti in Oceania, Nuova Zelanda, Australia, Azzorre, Sudafrica, Sudamerica e USA. produttore maggiore è gli USA segue il Mediterraneo (Europa e Africa), Asia e Sudamerica.

L'Italia (soprattutto la Sicilia) occupa un posto di rilievo nella produzione mondiale degli agrumi, con una quota attorno al 5% (paragonabile alla produzione giapponese e spagnola, ma molto inferiore a quella del Brasile e degli USA che producono rispettivamente il 25% e 20%).

In Italia la produzione di agrumi (arance, limoni, mandarini, clementina, bergamotto, chinotto) si concentra nelle regioni meridionali, con la Sicilia in prima fila (circa i due terzi della produzione nazionale), seguita dalla Calabria (circa un quarto) e a distanza da Campania, Puglia, Basilicata, Sardegna e altre regioni.

È molto apprezzata la produzione di agrumi nel Gargano che vanta specie autoctone e DOP sia di limone sia di arancia nei territori di San Menaio e di Rodi Garganico, nella cosiddetta oasi agrumaria.

    Spoiler alert: he ends up being King of Sweden through a marriage and
    a few deaths. He goes to court and refuses to defend the actions of a
    friend and finds the backdoor into the monarchy. No one knows how,
    but we certainly aren complaining. Actually if the "hair" was a
    part of the hat/helmet skin itself then this would be a non issue but I imagine the technical difficulties stem from the fact that each armor skin only comes in 1 or 2 versions depending on whether the race/gender combo uses
    different models. This 1 skin is then taken and jury rigged onto each racial frame.

    human hair wigs In February 2008, the Boys
    Varsity Wrestling Team claimed their 7th "banner" (conference championship) in 9
    years of participating in the MAAC. It was also their 4th straight banner.
    They established clear dominance, winning the tournament by over 100 points, and boasted
    8 MAAC champions and one additional All MAAC selection. That is VERY true, but
    also extremly tricky. Do you take them to ghetto neighborhoods that may reinforce their prejudice.
    Do you take them to places wehre they might not be
    accepted because of their past racist history. human hair wigs

    U Tip Extensions Go to a reputable running store and have them analyze your gait.
    They will then offer you a few choices in shoes
    that conform to that analysis. Put the shoes on and run on the treadmill for awhile to see how you like them.
    Using the mach number as a cruising speed automatically
    adjusts for non standard conditions, particularly air temperature.

    Pilots flying at a specific mach number know the expected fuel efficiency of their
    jet. Finally, the 300 knots indicated airspeed is going to
    be pretty close to the 0.78 to 0.80 desired
    cruise mach when the airliner reaches a cruise altitude in the 30,
    000 to 40,000 region where most airliners fly.. U Tip Extensions

    I Tip extensions I use the rogaine spray for men and my
    hairline is basically almost back. I used to look like Nick Cage, ha.
    It's a bit expensive and if I'd stop using it they'd fall out again apparently but I'm fine with it.
    Haddish stopped for a moment and used a napkin to wipe the tears from her eyes.
    "I've been through the shit," she said, not as a knock against herself or a way
    to build herself up just a simple fact. "I have come out of society's asshole, but guess what?" She took another pause as a massive
    smile broke out across her face. I Tip extensions

    clip in extensions "Initially I wanted to write an open letter to the big brands asking them to be more inclusive and be more diverse. But I thought, Why don't I do a billboard?. I can help but laugh at the comments about the wii fit, just because I just kinda accept it, and that thing is probably not accurate, and depending on the time of the day your weight can fluxuate. I find the facts and the exercises very helpful and man do they make me sweat! I find that the bmi and the fact that the mii is chunky motivating because it like yeah that what I am so lets chang it!! It really about the attitude and being positive, also accepting what you are right now and being proud that you changing it. Not only does it help you physically its emotionally as well clip in extensions.
