“Nature Climate Change” adl\u0131 bilim dergisinde yay\u0131mlanan ara\u015ft\u0131rmada, 10 farkl\u0131 tropikal a\u011fa\u00e7tan toplam 1400 fidan kullan\u0131ld\u0131.<\/p>\n
Daha sonra bu fidanlar iki gruba ayr\u0131ld\u0131.<\/p>\n

Ara\u015ft\u0131rmada” bitkilerin g\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131ndan faydalanarak fotosentez yapt\u0131klar\u0131” bilgisine yo\u011funla\u015f\u0131ld\u0131.<\/p>\n
\u0130lk grup fidanlar bir s\u00fcre karanl\u0131k bir ortamda b\u00fcy\u00fct\u00fcld\u00fc. Fidanlar sonra g\u00fcne\u015fe \u00e7\u0131kar\u0131ld\u0131.<\/p>\n
\u0130kinci gruptaki fidanlar ise \u00f6nce g\u00fcne\u015fe kondu sonra g\u00fcne\u015f g\u00f6rmeyen ortama al\u0131nd\u0131.<\/p>\n

NSC seviyeleri bask\u0131lanan fidanlar normal seviyede olanlara k\u0131yasla daha \u00e7abuk soldu.<\/p>\n
Oxford \u00dcnivesitesi’nden Prof. Andrew Hector, s\u00f6z konusu karbonhidrat bile\u015feninin gelecek i\u00e7in \u00f6ng\u00f6r\u00fclen iklim de\u011fi\u015fikli\u011fi modelleri i\u00e7in bir “sigorta” i\u015flevi g\u00f6rebilece\u011fini vurgulad\u0131.<\/p>\n
Prof. Hector, bu bulgunun uygulamaya ili\u015fkin sonu\u00e7lar\u0131yla ilgili olarak \u015funlar\u0131 s\u00f6zlerine ekledi:<\/p>\n
“Kurakl\u0131k zaman\u0131nda ormandaki hangi t\u00fcrlerin risk alt\u0131nda oldu\u011fu tespit edilebilir. Ayr\u0131ca bu veri, ormanlar\u0131n yeniden yap\u0131land\u0131r\u0131lmas\u0131 i\u00e7in kullan\u0131labilir. B\u00fcy\u00fck bir alana NSC seviyesi d\u00fc\u015f\u00fck a\u011fa\u00e7lar dikerseniz t\u00fcm alan kurakl\u0131kta zarar g\u00f6rebilir. Ancak farkl\u0131 a\u011fa\u00e7lar dikerek riski yayabiliriz. Bu durumda ormanlar dayan\u0131kl\u0131 a\u011fa\u00e7lar sayesinde varl\u0131klar\u0131n\u0131 devam ettirebilirler.”<\/p>\n
