Caoganlin'in \u00e7ay yapraklar\u0131n\u0131n ana biyokimyasal bile\u015fenleri \u00fczerindeki etkisi
\n\u00c7ay a\u011fac\u0131, d\u00fcnya \u00e7ap\u0131nda bir\u00e7ok \u00fclkede yayg\u0131n olarak ekilen, yapraklar\u0131 olan \u00e7ok y\u0131ll\u0131k ekonomik bir \u00fcr\u00fcnd\u00fcr. Yabanc\u0131 otlar g\u00fcbre, su ve b\u00fcy\u00fcme alan\u0131 i\u00e7in \u00e7ay a\u011fa\u00e7lar\u0131yla rekabet ederek \u00e7ay verimini ve kalitesini etkileyebilir. Glifosat, y\u00fcksek verimlilik, d\u00fc\u015f\u00fck maliyet ve geni\u015f yabanc\u0131 ot \u00f6ld\u00fcrme spektrumuna sahip yayg\u0131n bir sistemik herbisittir. Son y\u0131llarda, \u00e7ay bah\u00e7elerinde yabanc\u0131 ot y\u00f6netiminde yayg\u0131n olarak kullan\u0131lmaktad\u0131r. \u015eu anda, \u00c7in'de Fujian ve Guizhou gibi baz\u0131 eyaletler, \u00e7ay bah\u00e7elerinde glifosat kullan\u0131m\u0131n\u0131 k\u0131s\u0131tlamak i\u00e7in yerel d\u00fczenlemeler uygulamaya koymu\u015ftur. Ancak, \u00fcretim s\u0131ras\u0131nda yanl\u0131\u015f ila\u00e7 kullan\u0131m\u0131 nedeniyle \u00e7ay bah\u00e7elerinde glifosat kirlili\u011fini \u00f6nlemek hala zordur.<\/p>\n
Glifosat geni\u015f spektrumlu \u00f6zelliklere sahiptir. Yabani otlar\u0131 \u00f6ld\u00fcr\u00fcrken ayn\u0131 zamanda bitki k\u00f6kleri taraf\u0131ndan emilir ve bitki boyunca ta\u015f\u0131narak bitkinin b\u00fcy\u00fcmesini ve metabolizmas\u0131n\u0131 etkiler. Etki mekanizmas\u0131, bitki \u015fikimik asidinin metabolik yoluna m\u00fcdahale ederek aromatik amino asitlerin sentezini etkilemek ve bitkilerde metabolik bozukluklara neden olmakt\u0131r. Bu nedenle, bitki \u015fikimik asit metabolizmas\u0131 \u00fczerinde etkili olan glifosat s\u00fcreci ka\u00e7\u0131n\u0131lmaz olarak mahsul\u00fcn kalitesini etkileyecektir. \u00d6nceki \u00e7al\u0131\u015fmalar, glifosat uygulamas\u0131n\u0131n m\u0131s\u0131r, patates ve narenciye gibi \u00fcr\u00fcnlerin veriminde d\u00fc\u015f\u00fc\u015fe yol a\u00e7t\u0131\u011f\u0131n\u0131 g\u00f6stermi\u015ftir.
